Well, I took the plunge and ordered the 4 star afterall. It'll give me something to do until I get can the servos and receiver for this new plane. I want to strip the engine out of the trainer for now but I am leaving the receiver because the end of it has stripped wire and I'm concerned I'll damage it more if I try moving it. Instead I'll just keep testing the signal range on that receiver when I get an engine for that plane eventually again and get a new receiver for this new aircraft plus get some servos while I'm at it. I will probably start a build thread on this in the kit section soon. I won't have the kit until probably 2 weeks from now
