The weather worked out well for us. My apologies for the time for 2 pm to 7:30 when it was supposed to be 9:30 to 2 pm. Anyway, all had a good time. A total of 13 folks flew in. The farthest flight was from the St. Louis area (2 plus hours) and it was a pleasure to meet Tim and Jill.

Luann spend all of Friday getting the chili started so it would be yummy the next day. It was good seeing old and new faces.

There is a new playlist, ‘Wrench and Elbow Bendings’, watch them all!

We have started doing airplane stories telling part or all of the history of a particular airplane. Does your p[lane have a tale to tell?

We have started adding ‘Easter Eggs’ to our videos. This is normally a software term. But it now applies to a section of video or a photo at the very end of a video. Sort of a surprise.

The first Easter Egg was discovered and emailed by James Easterbrooks, is that coincidence or what?

Also new in the collection are safety videos made from FAA material. Don’t want it said we were concerned with safety.

Made a video of NOS parts and someone called right after it went public to buy those parts for their plane!

Yankee Serial Number

Start was 5601L (‘Oil’) at serial #3. Serial #24 was 5626L (25 and 26 were foreign sold) so the series corrected back at #27, 5627L.

5907L and 5606L are both in the original Yankee manual (owned by Ken’s flight school).

Robert and Meli Gow had N5601L (‘OIL’), serial #3.

Serial #4 was crashed before delivery.

#5 – Hal Beauchiense.

Cowl Latch Pin Spring Grommets

I would like to thank Jimmy Candeletti for his help in sourcing a size grommet that would work for this application, Many were tried, only one chosen.

Air Vents

About a year ago we sold a bunch of Ken’s air vent kits until we ran out. I have been working with many suppliers of there air vents and in a lot of cases we got as far as getting a sample to examine. Many tries that I should put in a basket and you can have them. Anyway I finally found the same ones as in Ken’s kit. Rivets I have but the metal plates have been hard to get made, they cost more that the vent.

Good news is that I had to get a minimum order (enough to do a good percent of the fleet) which means I have lots and they were fairly cheap. Since I am not selling kits the deal of two vents (which I prefer holding in with 4 screws) is $50 plus shipping.

Red Rudder Caps

We are working with a person who makes these for another brand of plane. Stay tuned!

Interior plastic

We are also working to have plastic made (by the same guy who used to do it for Fletchair) to make ship sets, including the Traveler, and two-plane which are hurting for rear plastic pieces.

During this ‘Shelter at Home’ time we are open to service the fleet. Nice to be back for awhile.

Canopy INSPECTION

There is more to your canopy than the single entry in the annual checklist. Here is what we look for as a start:

Latch and Latching (how well does it close, seal compression, lock)

Latch cover and placards

Double Bead Seal

Canopy Seal

How does canopy slide

Canopy stop bumpers installed inside?

Canopy bumpers and springs

Rails – clean, measure, swap

Tracks – clean

Front canopy seal

Rear Seal Canopy (felt)

Canopy ride bumpers

Canopy side windows and seals

Interior canopy plastic

Clean turtleneck under canopy while canopy is off

Candelari Mod Explained

Somewhere is the dark past, someone came up with the idea of a lower cowling deflector to create an area of low pressure by the exit ramps to help get the hot air out. It was used a lot at Hortman Aviation, and Jimmy Candeletti got credit for this mod.

Trim Plate Decode

Ken’s Memorial (among his parts)

 

Other than the parts, there was most of the crew from loading, Dan Baisley, Mark Matthews, Rich Harrison, and Jimmy Candeletti. Thanks to these guys who had it all possible.

 

Also as part of this process, I have many videos of Ken’s I have never used, but thought it would be a good idea to digitize them into movies and see what the B roll has on it. Look forward to hidden gems. One for sure will be all the AGAC Tooling in a warehouse along with file cabinets of aircraft paperwork and explanations of what each jig of tooling did in the larger project.

While going through Ken’s Videos and papers, we came across the article that Ken send me years ago. Enjoy this read.

‘Lack of degree no handicap for Ameromod manager’

EWERETT< WA – Don’t get into a conversation with Ken Blackman about aircraft modifications unless you have a lot of time. Blackman is general manager of Ameromod, which offers a number of mods, and his enthusiasm will keep your ears busy for quite a while.

But that’s no problem, because Ameromod’s programs can add zip and looks to your airplane. The company based at Paine Field, is best known for it Gulfstream (Grumman) American aircraft programs. There are 125 -, 150-, 160-, and 180-hp conversions for Yankees, Travelers and other GA airplanes. There are cowling and landing gear clean-up mods, soundproofing and interior-comfort mods, 10- and 20-gallon auxiliary fuel systems with gross weight increases, dorsal-fin and large-elevator installations, Sensenich propeller for the standard GA McCauley prop.

A turbocharged 180-hp conversion for the Tiger is in the works, as is a 200-hp fuel injected, constant speed conversion for all four-place models. A carburetor air intake and induction system conversion for some GA models is also under development at Ameromod.

Blackman, short, 41 and exuberant, rattle off facts and figures like a verbal Janes.   For instance, ask him about the 125-hp conversion for the Yankee and he’ll immediately tell you that the result is 126 to 131 mph cruise at 75 percent power at 8,000 feet. He’ll continue talking about the mod for the next twenty minutes. He;s especially proud of the company’s success in coming up with the for a bad vibration in original Tigers.

“ The problem was the McCauley prop at certain rpm,” he said. “It could cause eventual cracks and damage, and it led to an AD note that included an operating restriction arc. Eventually Grumman American and McCauley, working together, came up with a beefier prop to eliminate the required inspection every 100 hours, but there is still a vibration in a certain rpm arc.”

Meanwhile, Blackman and his crew discovered that when a Sensenich prop was installed on the Tiger the vibration disappeared, and they obtained an STC for the conversion.

As you might suspect, Blackman learned to fly in a 1971 GA Trainer, back when he a night club entertainer. The fixed-based operation he rented from closed, so “four or five of us die-hards bought one (a Yankee) and formed a flying club in 1975.”

The club evolved into Sky Trek Aviation, a flight school and GA dealer at Paine Field. Sky Trek’s sales made the outfit one of Grumman American’s top five dealers one year. However, in 1979 Grumman American decided to stop building single-engine two- and four-seaters, and Blackman and several associates formed Ameromod in 1980 to develop product support and modifications for Grumman American aircraft owners. Modifications are Blackman’s raison d’etre.

“I’ve always been one to pull out an engine and put in a bigger one, no matter what was in there to begin with,” he said. He flew his own Yankee for a year testing the 125-hp Lycoming O-235 installation before selling the ATC. “If it was going blow up, I wanted it to be my plane.”

But rarely does one of Blackman’s mods go awry. Although he has no formal training in aeronautics or engineering (he shipped college altogether) he is a natural genius in designing. “And a kid, I could sit and look at a design and come up with changes, like for a dune buggy, without putting anything on paper.”

Ameromod has two full-time mechanics, but Blackman is as likely to be found in the shop or hangar with them, thinking and tinkering , as he is to found behind his desk. His ideas aren’t limited to GA products, however. Realizing that the supple of GA single is finite, he helped develop mods for other aircraft. For instance, there’s the Sparrowhawk 152, which involves installation of a 125-hp Lycoming, and prop and spinner change, and a baffling-system modification. The new 152 can cruise at 117 knots at 75 percent power on six or seven gph, and it can climb to 16,000 feet.

Nonetheless. The GA singles remain Blackman’s passion (once he even tried to the GA product rights and tooling). In the future, look for a Tiger with stick controls, a 260-hp engine and Yankee wings called the “262.”

KEN BLACKMAN REMEMBERED

Good morning to all. My name is Sharon Spence, President of the AYA. I am not able to attend in person today due to a previous commitment and have asked Ronnie Mowery to represent myself and the AYA today as the Grumman Family remembers a very special man – Ken Blackman.

I am sure all in attendance today knew Ken as one of the Grumman Gurus and all his abilities in fixing planes near and far. Ken was a founding member of the AYA, he served as President, Convention Chair and Editor of the American Stat. He was a lifetime member of the AYA and a recipient of the Dicey Miller Award. BUT these are not the tings I remember about Ken.

I remember the first time I met Ken: it was at Ames, Iowa in 1986, my first convention. We had just bought our Tiger and flew it to Ames. I currently owned a Cheetah at this time and loved it and hated the Tiger and refused to sell the Cheetah. We were sitting one afternoon with a group of “experienced” Grumman owners who were talking about the “race car” handling of the Cheetah and Tiger. I could not believe my ears and I strongly voiced my opinion on the difference. The Cheetah handles like a dream, but the Tiger handles like a semi-truck. No one believed me, so we went out to the line where the Tiger was parked. Ken spotted our Canadian call letters and as we walked toward our Tiger said “I don’t believe it – you have “chopped ailerons”. For those who have never seen or heard of “chopped ailerons” this is what happened. The FAA issued and AD on the Tiger, owners were required to cut off the trailing edge of the ailerons to prevent “aileron flutter.” (Editor’s Note: This AD applied to all 4-place Grummans, not just the Tiger.) The previous owners were early compliers with this AD. Fortunately the AYA got involved got involved in this AD issue and through our then Technical Director, Jeff Simon, was instrumental in getting the FAA to accept an alternate methos of complying with the AD through a one-time inspection process and a logbook entry. (Editor’s Note: The method is SI 6101, service instruction also helped by Tiger Aircraft in WV.)

Anyway, it took Ken about 10 minutes and he was on the phone to Andy at North American Training College, Springbank, Alberta, CAN. Ken had found us a set of new ailerons. We left the convention the next day and flew to Springbank. We had our ailerons replaced and our Tiger flew like the Cheetah going home. I then agreed to sell the Cheetah!! Thanks to Ken.

I have a few more memories of Ken coming to our rescue. I won’t relate them all but I do have one more that I will share. We were flying home from a weekend trip to Cody and Thermopolis, WY. We stopped at Malta, MT for fuel on the way home. Fueled up and ready to go I turned the key and tried several times to start the plane (of course Jim said I folded it), but – it was a no go!! Fortunately there was a mechanic on the field. But, he had never worked on a Grumman before and after trying several different things and it still di not start we then phoned Ken. Ken diagnosed the problem over the phone, called somewhere down south, and had a new mag Fedexed to Malta, MT and in two days we were on our way home. Once again, Thank you Ken.

Ken was well known for his “wing nut” donation to the annual AYA conventions. Every table at the banquet would have a packet of wing nuts. (Editor’s Note: These were battery wing nuts.) There would be some sort of contest as to who would get the wing nuts. It is a memory that will not be forgotten. The AYA now has “The Ken Blackman Memorial Wing Nut Toss” contest at our conventions. It is a blast and once again, Thank you Ken!

I last visited with Ken at the AYA Convention in Paso Robles, CA in May 2017. We had a great chat, hugged each other, shared a tear or two and said how nice it was to see each other again. It had been too long.

In closing I just want to say, “thank you Ken for all the wonderful memories, you will be forever missed.”

“I’ve always been one to pull out an engine and put in a bigger one, no matter what was in there to begin with,” he said. He flew his own Yankee for a year testing the 125-hp Lycoming O-235 installation before selling the ATC. “If it was going blow up, I wanted it to be my plane.”

But rarely does one of Blackman’s mods go awry. Although he has no formal training in aeronautics or engineering (he shipped college altogether) he is a natural genius in designing. “And a kid, I could sit and look at a design and come up with changes, like for a dune buggy, without putting anything on paper.”

Ameromod has two full-time mechanics, but Blackman is as likely to be found in the shop or hangar with them, thinking and tinkering , as he is to found behind his desk. His ideas aren’t limited to GA products, however. Realizing that the supple of GA single is finite, he helped develop mods for other aircraft. For instance, there’s the Sparrowhawk 152, which involves installation of a 125-hp Lycoming, and prop and spinner change, and a baffling-system modification. The new 152 can cruise at 117 knots at 75 percent power on six or seven gph, and it can climb to 16,000 feet.

Nonetheless. The GA singles remain Blackman’s passion (once he even tried to the GA product rights and tooling). In the future, look for a Tiger with stick controls, a 260-hp engine and Yankee wings called the “262.”

KEN BLACKMAN REMEMBERED

Good morning to all. My name is Sharon Spence, President of the AYA. I am not able to attend in person today due to a previous commitment and have asked Ronnie Mowery to represent myself and the AYA today as the Grumman Family remembers a very special man – Ken Blackman.

I am sure all in attendance today knew Ken as one of the Grumman Gurus and all his abilities in fixing planes near and far. Ken was a founding member of the AYA, he served as President, Convention Chair and Editor of the American Stat. He was a lifetime member of the AYA and a recipient of the Dicey Miller Award. BUT these are not the tings I remember about Ken.

I remember the first time I met Ken: it was at Ames, Iowa in 1986, my first convention. We had just bought our Tiger and flew it to Ames. I currently owned a Cheetah at this time and loved it and hated the Tiger and refused to sell the Cheetah. We were sitting one afternoon with a group of “experienced” Grumman owners who were talking about the “race car” handling of the Cheetah and Tiger. I could not believe my ears and I strongly voiced my opinion on the difference. The Cheetah handles like a dream, but the Tiger handles like a semi-truck. No one believed me, so we went out to the line where the Tiger was parked. Ken spotted our Canadian call letters and as we walked toward our Tiger said “I don’t believe it – you have “chopped ailerons”. For those who have never seen or heard of “chopped ailerons” this is what happened. The FAA issued and AD on the Tiger, owners were required to cut off the trailing edge of the ailerons to prevent “aileron flutter.” (Editor’s Note: This AD applied to all 4-place Grummans, not just the Tiger.) The previous owners were early compliers with this AD. Fortunately the AYA got involved got involved in this AD issue and through our then Technical Director, Jeff Simon, was instrumental in getting the FAA to accept an alternate methos of complying with the AD through a one-time inspection process and a logbook entry. (Editor’s Note: The method is SI 6101, service instruction also helped by Tiger Aircraft in WV.)

Anyway, it took Ken about 10 minutes and he was on the phone to Andy at North American Training College, Springbank, Alberta, CAN. Ken had found us a set of new ailerons. We left the convention the next day and flew to Springbank. We had our ailerons replaced and our Tiger flew like the Cheetah going home. I then agreed to sell the Cheetah!! Thanks to Ken.

I have a few more memories of Ken coming to our rescue. I won’t relate them all but I do have one more that I will share. We were flying home from a weekend trip to Cody and Thermopolis, WY. We stopped at Malta, MT for fuel on the way home. Fueled up and ready to go I turned the key and tried several times to start the plane (of course Jim said I folded it), but – it was a no go!! Fortunately there was a mechanic on the field. But, he had never worked on a Grumman before and after trying several different things and it still di not start we then phoned Ken. Ken diagnosed the problem over the phone, called somewhere down south, and had a new mag Fedexed to Malta, MT and in two days we were on our way home. Once again, Thank you Ken.

Ken was well known for his “wing nut” donation to the annual AYA conventions. Every table at the banquet would have a packet of wing nuts. (Editor’s Note: These were battery wing nuts.) There would be some sort of contest as to who would get the wing nuts. It is a memory that will not be forgotten. The AYA now has “The Ken Blackman Memorial Wing Nut Toss” contest at our conventions. It is a blast and once again, Thank you Ken!

I last visited with Ken at the AYA Convention in Paso Robles, CA in May 2017. We had a great chat, hugged each other, shared a tear or two and said how nice it was to see each other again. It had been too long.

In closing I just want to say, “thank you Ken for all the wonderful memories, you will be forever missed.”

Canopy Air Locks are coming

Rumor has it that some 15 or so Airlocks are coming up this weekend. That is good so we will have some for door prizes and a bunch for sale. I’m told the price is $35 each.

Grumman Gang 25 years old as of May 4th

Hard to believe that 25 years have gone by since I joined, where did the time go? I thought the anniversary date was in the fall but Mark was kind enough to give me the correct date.

Back in the day, I remember attending a wine party at Jon and Ruth Maestre’s where we were all sharing our new emails addresses. Now look at us.

YouTube Videos

We have 695 videos now. Going to do one soon on the AK102A accessory kit that came out in 1970 for keeping the Yankees warmer in flight. Stay tuned.

Traveler Tips

by
Lou Evans, CFI/CFII/MEI/ATP

January 2019

Greetings and Happy New Year, “Grummanistas!” I hope all of you had a wonderful holiday season and I trust Santa brought all of the aviation-related “toys” that you asked for. For some of you, that would include an ADS-B Out solution for your aircraft given the looming FAA mandated deadline of January 1st, 2020.

Of course, this mandate does not apply to everyone. That is because this mandate, is an essence, an airspace ruling, and as such, is based on the airspace/ATC needs of the individual/aircraft involved. In other words, if you do not have a need to fly within the ADS-B Out required airspace as defined in 14 CFR 91.225, then you do not need to install this equipment in your aircraft.

If you are not sure what your ADS-B out aircraft requirements are, or will be, or you simply want more information about this aspect of the FAA’s NEXTGEN (Next Generation) program, be sure to go to the FAA’s website —www.faa.gov, and review the information provided therein.

My advice is, if this ruling applies to you kind of flying, and it will for most of us, then do this as soon as practical. This is because you will want to purchase a suitable ADS-B Out solution and have it installed by your avionics shop before the anticipated year’s-end mad rush to comply. Don’t forget that a flight test of the equipment to the FAA’s satisfaction, is also involved. Also, now’s a good time to reserve the FAA’s currently available $500 rebate before it is gone. That is because it is a limited number offer.

All this said, I would like to shift my emphasis for this month’s column to some personal notes. Namely, a note of gratitude, hope and encouragement to our association’s founder, president and heartbeat — Roscoe Roscoe, and his amazing wife, Luann.

As we all know, this past year has been one of immense trial and uncertainty for them both. Yet, through it all, they not only survived — they thrived and shone through it all — to the point of setting a great example on how to face long odds, true adversity, and yet —win. No doubt, the Grumman community at large is much better and friendlier with Roscoe and Luann amongst us.

Also, a tip of the hat to all of you who gave of your time, energy and resources to help Roscoe and Luann during this time of trial. Granted, their is not over. There are simply too many of you to name here, but I would like to offer at a minimum, special kudos to Jimmy and Mary Jo Candeletti, as well as Matt and Lynn Wing for their ongoing assistance to Roscoe and Luann.

I would also like to echo what so many of us have expressed in regards to the not-so-distant loss of our great Grumman guru and patriarch, Ken Blackman. Ken, was a tremendous friend and Grumman advocate and his expertise and support will be forever missed. Anytime I fly either of my two Grumman aircraft, I feel like Ken’s spirit goes up with me. That is because so much of how my plane has been maintained and exists because of quality tips and material provided by Ken.

The related good news is that Roscoe has purchased and coordinated the transfer of all of Ken’s Grumman equipment and parts, to Roscoe’s workshop as I write this. In turn, we, as a community will continue to have access to the parts and spares we need to keep our Grumman fleet flying.

Thank you, Roscoe, and may I say by all of us who love and fly Grumman airplanes — “Welcome back!”

For whatever reason, we had a huge bump in views of our videos just before Thanksgiving.

Scholarship

It would a perfect world if the GPA had enough extra money to be able to award a 1500 or 2500 dollar scholarship but alas we do not. So we chose a different method. We look at people who loved aviation and were going to stay in it with maybe even military flying. To this end we decided on a seeding program. After a suitable person was located, we would find a local pilot and have them take the person up in the left seat for an hour and let them see how a Grumman really flew. By doing this somewhere down the road/airway then would be able to counter anything negative that folks would say about our planes.

So if you know of a candidate and can safely fly right seat, let us know. We will pay for an hour of your fuel to show them our planes.

Here is what our first awardee had to say.

Scholarship Award

My aviation story begins differently from many other aviators: I have not always wanted to be a pilot. As a girl growing up in a small town in Indiana, it simply never occurred to me as an option. I had no aviators in my family, and since most pilots I encountered were older men who flew massive airliners or military jets, I couldn’t conceive of myself stepping into those shoes. But as I grew, the world changed, and so did I; and when I got to the end of my college career, unsure of my future and lacking any strong career ambitions, a basic career aptitude test illuminated my path like lightning in the night when it told me I would make a good pilot. That one word – “pilot” – strung together all the aspects of my personality and interests in a way that no other aspiration had before. I took a discovery flight, and that was the beginning of the end; I was irrevocably hooked on flying.

The problem from that point on was not ambition, but execution. I had just graduated college with a degree in political science, no viable job prospects in that field, and student loan debt; and, as we all know, flight training is not cheap. I chose to work a full-time job unrelated to aviation to fund my flight training at a Part 61 operation. I wanted to go at my own pace and pay as I went. However, my first year of “flight training” saw only 13 hours of flight time and an embarrassingly low amount of studying. I made the decision to move back home so I could put the money I was using on rent towards flying. The biggest change came when I was able to start working for the FBO at the Butler County Regional Airport, where I was taking my lessons. There is nothing more motivating than having an endless stream of aviation enthusiasts asking you about your flight training – you want to be able to tell them that you are progressing and loving every minute of it! With Blue Sky Flight Training, I got my private pilot’s license in just over a year and with 100 hours of flight time. I used that time to become as proficient as possible rather than just barely scraping by with the minimum amount of knowledge and experience to pass the check ride. I plan to continue with my training by earning my instrument and commercial ratings.

Aside from having consistent access to the rental aircraft and my instructor, working at the Butler County Airport has provided me with the opportunity to form many friendships on the field. Roscoe Rosche, owner of Yankee Aviation and prominent member of the Grumman Pilots Association, was kind enough to offer me a ride in a Grumman Cheetah with his good friend and fellow pilot Matt Wing. On a beautiful summer evening, Matt let me ride left seat as we flew northeast towards Richmond, IN, where I grew up. Everything about the airplane spoiled me, including the differential braking (I am notorious for over-braking during taxi – just ask my instructor – so this came naturally to me), the classic rock music that bled softly through the Bose headsets as we cruised, and the landing that came much more smoothly than what I was used to in a Cessna 172. Since then, I have also ridden in a Long EZ, several RV-8s, a Baron, a Pitts, a Ford Tri-Motor, and a King Air 350. Because of the generosity of Roscoe, Matt, and the many others on the field who have contributed to my interest in aviation, it has become a long-term goal of mine to ride in as many different types of general aviation aircraft as possible. Although I don’t have any blood relatives who are aviators, I have experienced how easy it is to find your own family within the aviation community, and I look forward to the day when I can generously share my passion with younger aviators as so many have done for me.

AirModsNW Move

As you know Ken Blackman passed away last May and his business ground to a halt. The shop was wanted by another mechanic (shop space in the Seattle area is hard to come by) so he was able to get it. Roscoe called the Blackman family and worked out a deal on all of Ken’s Grumman stuff at the shop.

Next order of business was to put together a crew and arrange transportation for all the Grumman parts. The first trailer was delivered December 14th, and loading started on Saturday. The second trailer was finished the following Monday and now both are on their way across the US to Yankee Aviation in Ohio.

I would like to thank Mark Matthews, Rich Harrison, Dan Baisley, Jimmy Candeletti, and Klaus Marx (IA for Ken for 10 years and who I trained under for my IA) for their help in loading and sorting through everything.

We are very happy to have saved all these Grumman parts to support the fleet.

First Yankee delivered 50 years ago.

It was in late 1968 that the first Yankee was delivered to a customer.

Service Calls and Requests

We also field a lot of call about information, manuals, etc, we are happy to help.

Cawley Aviation

Rudder Balancing was missing from the owners Maintenance manual. So we had them download our searchable pdf and get the missing 209 pages.

Contributed Video by Alex

Alex provided the raw video and we were able to make it into a video. Thanks Alex.

New Event this May

This event was suggested by Lou Evans and it is a great idea. Like the Wrench and Elbow bending, this weekend event will be heavy in social time and the BBQ will be running.

May 24-26, 2019 KHAO Event – Lots of social time

Twin Comanche trade for a Tiger.

We have a member out west who wants to go back to a Tiger. He is hoping a Tiger owner that is looking to upgrade might be interested in a trade.

DOM – ADSB Mandate Looming

Well they devoted a whole issue to it, so we are getting down to our last year.

Cabin Pressure

Great British humor from the BBC audio show MJN Air. These are great audio episodes and they make me laugh. Thanks Mark!

Server Move

Well we are all moved to the new servers, DNS set, and layout optimized. Thanks go to Jeff for finding us this bargain price per year for hosting. We saved more than 75% per year!

Manuals move and new Layout

As part of the server move, we could change max file upload size and we were able to get the bigger ones from Yankee Aviation website, so all our manuals are on this page with a new layout.     grummanpilotsassociation.com/info/manuals/

These are pdf’s that are searchable (via word or expression i.e. rudder will return you in the left pane every page that has rudder on it.

PowerFlow vs. Electronic Ignition

This two options cost about the same. They both increase engine performance and let us look at what this costs us.

Powerflow works by creating a vacuum on each cylinders as it begins to exhaust, so this help the engine breathe better. You will use about a gallon an hour more than a normal exhaust system, but you also get 4 – 7 % more power. Since the hot burning fuel is pulled out of the cylinder at supersonic speed a lot of heat is transferred to the valve guide, valve, and valve seat causing it to wear about twice the normal rate. For those who need this extra power they tend to replace their cylinders between 800 and 1000 hours with new.

ElectroAir Electronic Ignitions generate a 70,000-volt spark and deliver 10 – 14% more power due to the huge ignition spark and the timing advance. Makes the engine very smooth from idle all the way up. You can expect to save about a gallon an hour with the EIS for an O-320 and 2 gallons an hours for a six cylinders.

My recommendation is go with the EIS first, it is well worth it.

Cylinder Baffles for Traveller

Gary Vogt offered this, we put down for a set. Contact Gary who posted the following:

———————————————–

Other than the cylinder baffles for cylinders #1 & #2, the other baffles are
the same as the baffles on a Cheetah.

I have been hand making these baffles.

I have decided to have them professionally made and alodined.  They will be
pretty.  They will also be made out of 0.040 5052-H32 instead of .032.

If you want a set, let me know.  I need to make as many as necessary to lower
the per-part fabrication costs.

Thanks to Eric for donating the last 5 years of Service.

The old site was a learning experience and we made some upgrades as well as a few changes during the move. You will notice faster response time as well as a SSL certificate on the new servers. As an added plus we saved a few hundred dollars on the new hosting. Enjoy!

Volunteers

As you know the GPA is a volunteer group and I would like to thanks you all for your help and support. Special thanks goes out to Mark, Jeff, Jimmy, Matt and others you stepped up during my hospital stay of 10 weeks and kept you informed and the GPA running. Thanks you all very much.

Update

I know it has been a while since we put out a Newsletter so here is a short one.

I am home now from my hospital stay. We are slowly moving into the new house from the old one.

Computers moved – Videos to restart.

Doctor Visit

Had a good doctor visit this month, health is good and I am slowly working my way off the meds to get back to taking none.

Thanks you all for your wishes and prayers.
