Exactly, the servos will be worked harder, especially under load while the initial surface charge drops off... you're working the device at its upper voltage limit, shorting its life, so there is a small risk factor there...... I definitely would not go with the forward biased diode, I would upgrade to HV servos before playing around with stuff like that... would be fine for surface vehicles, but not with an aircraft.

No issues burning up any servos
I'll look into it... I could get my super cub under 20 pounds if I could go all A123, right now it weighs 20.6 lb's

***EDIT***

Just a quick note: a quote from the GF40 ignition module spec's... so again I go by the mfg's instructions, and I won't use a regulator on the ignition system either, so I use NiMh.

Ignition Battery: 4.8-6.0V NiCd or NiMH, 6.6V LiFe or 7.4V LiPo pack
LiPo battery requires voltage regulator
John M,
