I just bought a Falcon 40 and have been using the stock 4 channel Tx. I'm wanting to change the Rx frequency so I can use my Futaba computer radio. Will Futaba Rx crystals work? If not, it looks like you have to order a Tx/Rx set.

Just got done spending a couple hours searching this site and another for the answer, but nothing.

Any help would be appreciated.
