RE: I Saw it! TF 60 Size Corsair ARF!!!!!
If it weighs less than 10 lb as advertised, it won't need anything bigger than they are recommending. I've got a Saito .91, which I know is capable of swinging Master Airscrew 3 blade 14 x 7, and I also know that combination will be all that's needed for me in this model.
