I’ve discovered my Tach is not correctly metering the time. It is about 60% of my Hobbs time. I also recently flew one flight to verify, flying at 2300 RPM, so my time on my watch and the tach time should be identical. And I still was getting about 60% compared to the Hobbs.
Is there a repair process, or is it just more practical to buy a…[Read more]
Put the non-impulse coupled one on the right mag, then yo0u will start on both since the EIS controller fires at TDC during cranking.
The prop will be needed as a better airfoil and more pitch than the McCauley.
Thank you for your time to answer my question(s). I take it you do NOT recommend the prop..??
I went on Aircraft Spruce to see which application would be appropriate for my AA5A and found the following:
•EIS-41000 Direct Drive (non-impulse coupled)
•EIS-41000IC Impulse Coupled
Why I’m confused is because I was always under the impre…[Read more]
Definitely recommend the high compression, saves you about a gallon an hour plus more power. You want Electronic Ignition over powerflow (they cost about the same) but the powerflow uses more gas and the EIS 41000 saves you another gallon an hour plus easier starts and high altitude performance due to the 70,000 volt spark and power…[Read more]
I have a 1979 AA5A with2025:11 TTAF. My motor has not been overhauled since new. Yes I realize it’s pasted the suggested TBO but also the calendar time. My compressions are fine, in the mid to low 70s and since I thinking of having it overhauled with the high compression pistons, I’d also like to know how (if any) I could increase the per…[Read more]
Looking for a low time engine to replace the one on my AA1A trainer. Previous owner had a prop strike. I can’t decide whether or not to fork out for the STC or just throw a mid-to-low Time O-235 on just so that I can fly it.
