RE: Futaba crystal in a Hitec receiver
Theres also the posibility that the recievers, multiplexers are not compatable with the crystal. There are a number of posts and threads on this subject and the conclusion seems to be while there is no actual evidence of this type of incompatability its just not worth the extra couple of bucks for using a Hitec crystal and Futaba RX, or vise versa. Because there are alleged issues of this nature, there are opionions of some of the electronic guru's here on RCU that that say it could very well be the issue.
