I bought a earlier model T-Rex 600E heli from my good friend 6 years ago and haven't flown it yet. I bought the FunKey Airwolf fuselage kit for it from jettechmodels in Japan, and just realized a couple weeks ago that my frame isn't the correct style for the fuselage. I'm supposed to use a 600E Pro DFC heli setup for it according to their website, but I've seen a video online of a T-Rex 600 ESP being used for it.

Question is, can I buy the recommended frame and all related parts to convert my Heli to be able to use my Airwolf fuselage, or should I just sell my Heli and buy the one I need?

Thanks for any help you can give me.

Nobody has any information at all?

I thought all the electric heli people would have some positive information to add, so that I can know which heli model to start looking for.
