Well went to take it for a spin in the dirt and the drive motors would barely turn. Or turned in tiny spurts. Kept pushing and pushing, finally the Sabertooth ESC just got really hot. None of the LED's lit up, it just got hot. So I measured the amps the motors pull by holding one of the tracks in my hand and connecting a 2S 7.4v lipo, I applied for a second and highest I saw was 17amps and it wasn't stalled, I let go because I didn't want to break anything. I thought the 2x5 Sabertooth would of been up to the job because supposedly the motors only pull a max of ~3amps. Well maybe when they aren't geared down.

Anyway just ordered the 2x12 Sabertooth.
Also explains the stopping and starting yesterday when driving over 100 feet through the field after the pump battery died.

I have two Hobbyking 40amp brushed esc's but the low 16khz switching speed and the resultant sound drives me insane! I was using one on a car today and from over 60 feet away you could hear it when going slow.
