Have an almost new Futaba synth module for my 9C radio . Was setting up planes yesterday and the module got hot & quit working on some channels. Installed the fixed module and every thing worked fine. This AM when the module was cold it worked. I do not trust sending up some good planes with it not working. Can it be test?? Any one had this trouble??? I really do not want to fly multi $000 planes if i'm not sure the thing is going to work. Thanks for the Help

They can be tested. I had sent in a number of modules and RXs to Radio South for Tony to check out. I had one that was burnt out and had it repaired.
