Also, why are you running that much drag brake in a 4wd?!? Does it nose dive like crazy?

Just what I had it on.

Does it nose dive like crazy?

Now that you say that I was thinking it was the bad track.
I will take out the Drag brake

Thank you Doogie and Wildcat




Maybe 16 pinion will help too

Internal Gear ratio: 4.3
Pinion:16
Spur 44

Final Ratio 11.83
34440 rpm
Speed 40

To get little more pop

But it maybe like you all said the forward power was down
I would also look at going to an 18 or 19t pinion... I know it seems high, but that motor needs to be in the sweet spot, and I think you are way undergeared. Making all those changes should get you a very quick buggy with power to spare.
