Hey Jez 33

I was actually initially running cool power 30 heli. I had been running it on my os fl 70 and figured heli fuel should work in a heli. Well i was wrong, i don't think it has castor. It blew its cam rod using that fuel. Got a new one on waranty and had better results on 15% with castor. I converted to a corona with accelent results. Let me tell you though, that is pricey.

I don't think there is a defenet result to fix these motors. There problem, i believe, is mostly in there horrible carb. Some people have gotten a good one. I personaly think the engine is to small in the first place for the heli. I solid size would be a .12 racing engine. If i could, i would buy an os 12 with the smallest gears you can find, convert to the corona long blades and boom. Put some 2 dot grips on and have a blast.
