Really appreciate help Spaceman spiff, (liked your th/pitch advice too)my os30 will only run 1 1/4 turns out with 15 % nitro. Still very hot.
Bought heli 2nd hand so think i will replace eng.
Anyone know if i can squeeze the os 50 in there? Would love more power. I feel like a beginner again after flying planes, although the planes seem real easy now.
thanks
JA
