Barracudahockey,

Where do you have your needle set on your Hyper 50? I had to lean out the idle and the main is 1 or 2 click past 1 turn open. It idles perfectly without the blades turning and has nice throttle response. I'm running CoolPower 15% Heli fuel with OS#8 plug. The engine will richen up when the tank is below half, I expected it to lean out below half.

Just afraid to run it to lean, I already put a new piston and ring in it from running it with Omega 15%.
