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
Servos are not channel specific. They are ALL pretty much generic as to their use. In other words, most of the modern servos can be used interchangeably with most receivers. There may be some exceptions, but those are few and far between. So, if you have a Hitec, or an Airtronics, or a Futaba, or whatever servo, and they have the same connector, chances are very good that they will all work on just about any receiver. As stated, the Futaba's need to have the tab trimmed to be used on other receivers... but they work just fine on them.
The only suggestion I can offer here is that you don't mix and match servos for applications. For instance, if you have a setup that uses two servos for the ailerons, then stick with the same model and type servo on both sides... ie Airtronics 94102Z on both sides, or any other "matched" pair, be it Futaba, JR/Spektrum, Hitec, whatever.. keep them the same.
Enough has been said about crystals.
