I use one pack- a 900ma KANN NIMH . (4 ozs)
The plane uses aprox 200 ma per flight -which I replenish using a EFlight Pinnacle Charger - It displays the amps used .
The 9411/SA-exactly same servos except for gears
Instructions do not recommed it -but the 811 servos will also work-
The caveat is that you should back off the throws off the surfaces somewhat .
Personally I have used these servos in very similar setups with no problems whatsoever
I use the LiPos only in my electric planes.
