I have the FPE 2.4 in mine. It is a great combo. The FPE takes about 3 gallons to get broken in and running smooth - the first gallon was especially rough on mine - then it is awesome. I'm on 4 gallons now and it runs just as smooth as a big Nitro 2-stroker. On mine I upgraded ignition to CH with 28 degree hub, blocked 1 stinger and I am swinging a Biela 20x10 at 6600 RPM on the ground. It gains about 100 RPM with every extra gallon I put through it.

The plane is not a "floater" with this engine but I actually find it the easiest plane I have to land - the weight is just right. It flies IMAC great. I didn't know the meaning of floater until I tried my WH Composite Sukhoi - now that thing is a floater... in fact its hard as hell to make it land at all HA HA. I prefer a little more wing loading.
