You can use the FrSky FF-1 2,4 GHz combo pack for Futaba w/ module and receiver or the FrSky FD 2,4 GHz combo pack for Futaba w/ module and receiver in the 3VC and in the FF3. It is just taking the 40 MHz module out and replacing it with the FrSky module. I have been doing this for the last 2 years without any issues. Also converted a Sanwa Super Exzess and a KO Esprit II with the DIY pack. Works a treat!
