thanks for the info guys! think im going to have fun with this. itll be a good, inexpensive engine to start with. (probably more than i should have paid, but much less than the new one i was looking at). i found a parts list, and instructions for setup. now all i have to do is figure out how to mount it in the plane. next thing i have to pick up are all the servos. any good suggestions? im trying to get some jr ds821's cheap.  was hoping to go digital. thanks again!!
