It should be OK unless spikes from starting/stopping
your turret motor causes momentary radio glitches.

As an example, I use four C batteries to power my radio
Rx, two standard servos and my motor controller.  I change
them before every battle.  When they get low, firing the
trigger servo creates a momentary radio glitch that causes
my Hetzer to jerk backward about 1/4 inch.  It is cool
because it looks like recoil but it ruins long-range aiming.
