Hay Bryant50,
Good luck getting anything out of Nitro Planes. Their customer service sucks hind wind...serious hind wind.

I have a set of Troy Built F6F retracts coming to me for my CMP Hellcat. Troy Built Models Hellcat has a 72" wing span and CMP has 70" so these should do the trick. I did have a set of Lado rotating retracts, but a buddy in my club had needed them (he sent his into Lado for repair and never got them back)...and I also felt that the Lado's weren't strong enough for the weight of this model. I plan on going with a twin Fox 1.20...that is if I can get the Fox to run well enough for me. If not, then I may go with a small gas engine.

What size gas engine would you guys recomend and has anyone installed a small gas engine into this kit ?

Thanks...
Soft Landings Always,
Bobby of Maui
