It's a JR PROPO radio control transmitter. JR expressly forbid LiPo packs in their Tx's cos without regulation the high voltage (a 3 cell lipo is 12.6 volts fresh off charge) can kill the linear regulator in the radio. I tend to charge the transmitter overnight on a friday night ready to go flying on saturday morning. thanks for your input jon 2008/5/29 David VanHorn : > > The actual pack I intend to charge with it is a 1500mAh 8 cell NiMH.
