Default os .25 question.
I have an os .25 that we race pylon with. I am currently running 15% nitro in it.
Would it hurt it to run 30% heli fuel through it ? Would I have to do anything thing to the motor to do this?

Should I expect a big gain in top end RPM with 30% ??? IF so what? 500 RPM??? 1000RPM ???


Thank you in advance
