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.
Hmmm, I need to look into this. Everything I've read says the diode prevents discharging. On the few occasions that I actually cycle my Tx battery pack, I pull it out of the transmitter.
