Hi:

I bought a used Radio Futaba Conquest 4NBF 4 Channel radio 72Mhz, a Futaba buddy box and a trainer cord, for the purpose of training. BTW, channel is 26, without servo and receiver.

My friend has a 72 Mhz 4 channel trainner plane without buddy box and trainer cord at channel 51.

Can I plug in his crystal of channel 51 into my transimitter in order to use my transimitter and the buddy box? I believe his plane receiver can receive from my transimitter since they are same brand crystal with same set frequency.

Could anyone please advise?

Thanks!
