I have the stock HB A7. Flew it but want more power without having to change the engine.
I'm gong to try flapperons for takeoff, as I'm flying from grass. (with bigger wheels)
I have flown it many times already but want some info/instruction on how to make the tailpipe smaller at the exit and what effect this has and why.
I've seen the A7 edf conversion has a smaller tailpipe exit, just wondered if this would give me a little more speed.
Please help
Dave
