That sounds like it should be a great combination. I would like to have a 4 stroke in one, but I already have the OS 91 FX and need to use it. Keep me updated on how it flies! I have a GP 1/4 scale Giles with a Saito 180 that flies great, but would like something that the pucker factor would be a little lower on for everyday flying. Do you plan on having it ready soon?
