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

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

RE: WHAT ENGINE FOR HARRIER 90
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.
