Brushless Maxx hesitates

[steve050773]

Alright guys -

Got to do a better test with the ESC direct soldered to the motor and there was an improvement.

On a smooth surface, I don't see any hesitation. If I go off into grass, there is still hesitation when I make any substantial stab at the throttle.

However, I did notice that reverse seems to move at a pretty good speed irregardless of the surface. Could it be that reverse has some type of program limitation on the 9920 (25% power, or 50% power) and this limits the strain I'm putting on the esc?

Next, I'm going to try and redo all of the battery connections. If that doesn't change anything then I know I'm probably down to a controller issue.

Any thoughts? Any recommendations on a better controller?
