northerner21,
If it is an acution on Ebay or something. Email the seller and specifically ask him whether the servos come with the plane ect...
Also, ask whether the plane has ever been crashed
If the plane has been crashed and he is selling the RX with it, don't use it unless he or you sends it back for repair and service. Even a hard(I do mean
hard ) landing can damage a RX crystal.
If you are just learning to fly, buying a used plane is a great way to get into the hobby. But, unless you know the person you get the radio from, be very cautious. (some people drop the radios or knock them over and never think about it damaging the radio)
The thing I hate to see most, is a new person take thier plane out and loose it on the first flight with a bad radio.
If you can afford the new radio go for it. If not, at least have some of the guys where you plan to fly help you do a range check on the radio and check the servos out.
Have fun!!!!!!
