Sounds good to me
'Course, everything sounds good to me (I'm a witless newby)
Seriously, I'm just starting on the Lazy Bee arf. I have an O.S. .15 LA engine from my powered chute which I couldn't get to fly.
I've no idea the difference btw the FP and the LA models, and I don't have a tacho either. I just like the engine - easy starting little sucker, and quiet too.
I'm going to get the power prop you suggested because I don't care about top end... gluck
