Default Futaba 127DF receiver question please!!!!!!!!!!!!!!

Hi there, i received on a trade a plane and it came with a futaba receiver 127DF, it has a ch 38 receiver crystal.
Well the question is:
All my radios and receivers are in ch 39, so how recomended or safe is to change the receiver with ch38 and put a ch 39 crystal?
Thanks.

It should be okay to just change the crystal being so close in frequencies without having to retune the Rx to match the new crystal, but do a thorough range check before committing a model with it to flight with it just to be sure, and of course use a Futaba crystal.

Be carefull with allR127DF, they are not the sameas the majority of other Futabareceivers. Please refer to:

. Futaba - R127DF - an old Hi/Low Band RX prone to vibration and jitters

. Futaba - R127DF..Channel cannot be changed by simply swapping crystal, must be retuned each time.

For all versions of the Futaba R127DF receiver, a channel 38 can be changed to channel 39 by simply replacing the crystal. You should suffer no problems at all. Of course, you will perform normal operational and range checking each time before you fly.
