JR transmitter
Finished building my plane, had been using the radio the entire time to set up the controls on the plane. I finished and charged all batt. Turned on the Jr radio and nothing, no led, no movement of any kind, checked with another known good batt. still nothing. Checked fuse, ok, power to board but that was it. This totally sucked as I had all JR servos and reciever, already mounted.Anyone have any ideas?

My Feedback: (1)
I had a "senior moment" last month and plugged one of my JR transmitters into a Futaba charger!
I popped that fuse and had no spares and no LHS within 40 miles (as if they would have one anyway). My local Radio Shack came to my rescue with suitable replacements.
The bad news is two weeks ago when Radio Shack announced it was closing many of it's stores, my local Radio Shack was on the to be closed list.

Had a JR radio about 10 years ago. All others were Futaba. Not thinking, I plugged the JR into the Futaba charger. Herd a pop sound and nothing worked. JR's are reverse polarity to other radios. Took it in to Pete Waters for repair. It blew a diod because of the reverse polarity. Safety feature to protect the radio for this reason. Cost about $25 for the repair.
