Also be careful using any type of discharger on a Futaba TX. Some models have a diode in them that if you use a discharger while the battery is in the TX then you will blow out the diode and then you'll need to send the radio in to get it fixed.

I had this happen to a customer at the LHS I work part time for. I sold him the Hobbico Elite because he wanted a decent chager/discharger but never asked about the TX. He came back the next day and said this was a known issue with certain Futaba's. I cannot remember the model it was, but it was not that old. So check first.

I've done this succesfully with both the 6102 and 9303 JR TX's
