Mixing Hitec and Futaba Crystals
A buddy of mine has had a lot of trouble with radio problems. Kind of intermittent-mulitple planes and receivers. It doesn't seem to be radio related as I tried my radio turned to his channel and he had similar problems. He has noticed that a vendor(they will remain nameless at this point) seemed to have randomly sent whatever brand of crystal they had with each recevier order.
In other words, they sent a Futaba crystal for a Hitec and visa versa.
My question is if they two crystal are interchangeable or could it be part of his problem?
