What's the deal w/ having to use a single conversion crystal ? My futaba rx has a dual conversion crystal in it. Put it in the RX that came w/ the cppro and it wouldn't arm. So, I called the LHS to oder the Futaba Short Single conversion crystal. Hope it works, will help tame the cppro down a great deal ! If it does, gonna be fun programming the TX

Thanks very much Atzanik
