Battery question

[Joe Dunnaway]

Hi Terry,
 I put one of those cheap Hobbico "VoltWatch" LED displays in my plane.  I
have 4 digital servos and during the 3rd flight, the display will show in
the green with the engine off but is bumping the red with the engine
running. I'm running a 1600 mah 4 cell Nihm pack. It's amaziing how much
current these digital servos are drawing just to stay centered with the
motor is running.
