I have accumulated just over 26hrs in phase one and all seems to work very well.
Couple of things I have observed that I am more curious about than concerned.
Engine set up is AeroSport 260HP, AFP injection, Light speed ignition on the top and magnetos on the bottom. Exactly the same installation I had on my RV-8 and no trouble for 450 hrs.
1: On the run up check at 1700RPM, when I turn off the LSI, the RPM drops
300 RPM.
The mag has been checked and is dead on. I have checked in flight at 2400RPM and the drop is only about 40 (forty) RPM.
The drop on run up just seems excessive, why is that?
2: The engine runs very strong and smooth in climb and cruise.
When I start a descent from level cruise, mixture still lean, I get a slightly
rough running engine. I would say that it does this as soon as the prop
pushes the engine. Just wondering if others have observed the same thing
or if I should investigate further.
I have always left the mixture lean for descent as you can not over lean at
less than 50% power. I generally set the mixture rich on my downwind along with my landing check list.
I have turned mag and LSI off on descent but it makes no difference.
Pushing the mixture full rich seems the only thing that will improve smoothness. I am not concerned about it but curious if anyone else made the same observation.
