Hi JLK,


When attached to your Realflight, you should remove the module from the radio. This will prevent an accidental RF output and save the module from any problems due to overheating.
If you have a 9C Super the module cannot be in the transmitter or the program will not run right.

I hope you find this information helpful. You can also reach our Futaba support team at 217-398-8970 opt 2, or via fax at 217-398-7721.

Sincerely,
Krysta Hunt
