Hi, I am new to helicopters and I bought a Nexus 30/w O.S. 30sx-H. My question i how do I break in this engine. It is new. I have broken in airplane engines but never a heli. Do I leave it in the heli or takeit out? All I have is 15% nitro will this be ok? Thanks to anyone who can help and/or give instuctions on how to do it.

Thanks Again,
Allmostthere
