I got confused; first it sounded like you switched to a bigger prop with less pitch, then I thought you said to go to a shorter prop with more pitch? I've been thinking about changing props for when I get my low-wing sport plane flying (Nexstar right now, 11x5, 46AX) was thinking of flying the Pulse with a 12x4 with the 46AX to start. Are you saying I should go the other way?
OH NO! You are doing A-OK just as you are doing. I was only adding background info. for you to use as you experiment with different set-ups. Some models have very different flight characteristics with slight changes in props. Others don't have so much change and it's fun just to play around and see what happens. YOU make it do what YOU want.
Basically an engine operates well in some particular RPM range. For an engine that is happy in the 11-13000 RPM range, with an average sport airframe, Long dia. low pitch props will produce more lugging power but less speed. Fast on acceleration, but slow in cruise. Rather like driving in 2nd gear.
OTOH, a shorter diameter prop operating in the same RPM range with higher pitch is in Hi-Gear. Slow to start off, but faster in cruise.
Thanks for the Kudos. It's amazing what I get out of flying alone, not worrying what my trainer is thinking! I wonder what he'd say when I tell him I want to cut the dihedral out of my trainer!
With the way you are going, he might very well offer you a knife.
