Good to hear that

I have your same engine. I've only ran about 7 tanks through it in a 3 week period and its still very tight, but it revs like crazy
One thing I noticed today is that it picks up lots of heat... I was running it today around a pking lot with 4 1/2 turns on the top and when measured the temp it was 280F

@25% nitro
What's your experience with temps and needle settings on this engine?
