Top Secret, FFF Eyes Only
I picked up this engine in Japan last fall. It is a Saito 56F, the F stands for Fun Fly. It seems just as strong as my old one that I flew in my Sudokhoi. The advertising that I can find on it says that it has a modified carburetor and valve timing. Other than that the only difference that can be seem externally is the red anodized prop hub. The box though seems to be way cool and is probably worth more as a conversation piece! I mentioned it in a different post and someone said they had "FFF" cast into the backplate and it stands for "Fun Fly Fanatic". Enjoy.
