combat engines?

[watnsee]

I was just inquiring as to what the hot power plant is for .30 rc combat? Im currently running a novvarossi 21 on a mousse can.
22000 rpm with an 8-4, 19000 9-4, waiting for good day to try a 10-4. all are master airscrew.

The best all around engine IMHO is the .25 OS FX on a mousse can 9X4 MAS prop around 19500 RPMs and super reliable

I agree on the OS 25 FX. It takes a licking and keeps on spinning. :D
