9757, I run a Saito 82 on 30% fuel and a Zinger pro 15x4. The pull out power is unreal but the overall speed is not much. However speed is not what i was after. I could easily run a higher pitch prop but I don't sport fly at all with this plane. I have a Sig SE a Goldberg Ult and a QQ 72" Yak. All of these are better at sport and IMAC type flying than the F50X. The F50x is my 3D plane. It does things the other planes will not come close to doing. The Yak is the best all around flier off the 4 I mentioned. It will do about anything you throw at it but not as radically as the F50x. I got a OMP Fusion from Santa. I hope it is as fun as the F50X.
