Jack Smash: your right, but these days radio companies pretty much expect people to use rechargeables. So all the modern transmitters will work just fine with the lower voltage.
I have never noticed any lower singnal quality because of using rechargeables. Heck my new radio even comes with a rechargeable pack instead of a dry cell tray.
The pack is pretty low on the mah, so I'm going to build me a new one with 1600mah or 1800mah cells.
