Found this guide to use a 2.4 ghz module from a HK/FLYSKY radio as donor for other expenssive FM radio.

Searched for this when medicineman said he loves his futaba skysport but wanted to win the sweepstake 2.4gh radio just for the "2.4ghz".

It says the module can be used on another radio and the donor radio can be used as a sim controller.

Anyone tried salvaging before?
