Brushless Maxx hesitates

I have a UE lightning chassis (aluminum). I haven't thought about trying a plastic chassis - makes me ill to think about running plastic with this much power.

Here are some closer pics of the layout.




I'm really beginning to think its the controller to motor wiring. Spent a lot of time just tooling around in the drive way and the hesitation really only occurs when I ask for more than 1/8th or so of throttle. Consistently, and the hesitation is worse if I try to go full throttle. I find it hard to believe that its interference because it was so predictable. I did reprogram the controller and no change occurred; I also tried a different radio/receiver and no change.

Here's what the motor and controller wires originally looked like:



Do you think I should try and direct wire them or use some 4mm plugs instead of 3.5mm? Or do you think I'm just on the wrong path all together?
