fm crystal

[crazyjr]

My info comes from a Novak XXtra synth reciever. if you look at the first number there is two differing types, first there is the hitec/futaba (top numbers on the POT and there is the KO/Air/JR side (bottom). Looking at that, I figure a futaba crystal will work in a hitec and vice vera. the others will mix and match on their side (KO/Air/jr). I personally seen an airtronics reciever with a Jr crystal work with a JR transmitter(XS3)
