the one that makes it fly best

RE: WHAT ENGINE FOR HARRIER 90
 

Hi,
Do you think the ST90 (new) would be enough for strong 3D performance? If it's enough power, which prop would you suggest?
thanks

RTD - I fitted a ST G90 into mine, had a 15x4W ... was not much performance. I was hanging at about 80% throttle.

RTD i have a super tiger 75 yes a 75 :) in my harrier 90 and considering the size of the engine is it flies not to bad hangs on bout 70-80% throttle and just has a enough to pull out although maybe a little bit more power would be nice sometimes im have great fun with it. Running it on a 14x4W on Contest 10% fuel

I'm running a O.S. 91FX with a 15x4 prop. Has great power to weight. Accelerates Straight up and hovers on about 2/3 throttle.

I've tried a a 14x6 prop to start but noticed some prop "stalling" at hover. Sounded like it was buzzing. Went to a 16x4, but seemed to throttle up a little slow. 15x4 has nearlyt instant response and uses less throttle to hover than the 14x6.
