I'm using a Sabertooth 2x12 and it seems to have some strange characteristics on the built in mixing. All straight movements on the stick seem to have half power, and all diagonal movement (so moving only one motor) seems to have twice the power.

Dimension Engineering said this was odd, and suggested that maybe my battery just couldn't supply the amps to turn both motors at full whack simultaneously.

I thought this too, but I'm using a 3S 20c 2650mah Li-Po which should be able to supply more than enough power.

Obviously this is causing me great problems since I lack torque to tank turn effectively and my straight line speed and acceleration is half what it could be.

Any ideas? (I'm using those MFA Como motors)

Cheers,
