Oh goody... here we go again.... the magic of LiPo cells....
Nice sales pitch there Andy..
Purchase a radio which supports in-system charging of LiPo, such as Spektrum DX8 or DX10t.
Once again I have just repaired a JR transmitter (that was designed to use NiCad or NiMH) that was used with a LiPo pack. Excess voltage caused a transistor to short out, luckily no secondary damage was done. IF you are going to use higher than designed supply systems, please fit diodes to drop that voltage down to an acceptable level.
I agree that for Tx's that were not designed for LiPos, using 2 Diodes to drop the voltage a bit is cheap and easy protection. You can always just charge to 11.7v, as well.
