new 37SZ-H Problem
I have about 2 gallons of rich's Brew 25% Nitro Heli fuel through this motor, break in was with 10%. I have switched to Cool Power 30% Heli fuel, and am having problems with going through glow plugs, and overheating within a few minutes of mid throttle run, I am still learning so no full throttle. She will start to lose power, back off on throtle, regains power, till load is placed. I have it running pretty rich, blowing lots of smoke, and lots of oil on Helicopter. This is in a Thunder tiger Raptor 30v2. 1 glow per 5 minutes run, and engine has always been run rich.
