This trainer cord is designed to go between two Futaba radios. (For users of the RealFlight G2 USB Interlink Controller please see the Comments section below) This comes with the "Micro" plug on BOTH ends. This trainer cord also fits the Tower 4-TH radio, Futaba 9C, 6EXA, and 4YF. INCLUDES: One Black Micro to Micro Trainer Cord REQUIRES: This requires that "2" Futaba radios that require the micro plug are used together. COMMENTS: This will NOT work, nor can it be modified to work with any other radio systems. For users of the Futaba 9C with the RealFlight G2 USB Interlink Controller: this trainer cord can be used for connecting the 9C radio to the USB Interlink Controller. A smaller adapter cord for using the 9C radio with the Interlink Controller is in development and will be released at a later date. 03/20/02 ats kh1-28-02 ir/kh
