Just plain new at this and I was wondering if the servos are compatable with most receivers etc. If a radio is on say channel 42 crystal and the Rx is the same of course, would a different servo work ? Hope I asked that correctly. If i was to build a new plane and put the required servos would my old radio gear operate. Getting myself off now so I will quit. I did purchase a new used radio trans that operates on 46 I think and my old reciever is 42 so I think my crystals have to match and both be from the same famly so to speak. Ok there it is for what its worth. lol Thanks and I will be watching. gphil
