Which batteries and regs are you using? Do most guys run redundant Rx power?

I have the Tech-Aero adjustable reg and will likely use a small 800-mAh 2S LiPo.

The S9154 aileron servos are rated for 4.8v only, although the Futaba website says they can operate safely at 6 volts, but not above that. A freshly charged 5-cell NiCd or NiMH puts out about 7.2 volts, hence the 4.8v recommendation. With the reg set at 5.8v it will be perfect with the LiPo.
