Trainer Cord
 

Will the FUTM 4420 Trainer Cord work between my FP-T7FGH FM Transmitter as the Slave transmitter and my T7C 2.4 FASST Transmitter as the Master for Training students. Or must I buy the 4Y Trainer Box because compatibility issues and Trainer Cord end issues. I the FP-T7FGH FM is useable for this it would enable me to make use of more features for the Student.

Thank You, Darryl Zempel

They should work together because the old 7FGH transmitter uses the same-voltage battery pack as the 7C.
