I tried changing wires around, changing the settings on the transmitter. No matter what I did when I pulled the throttle back, the motor spun the tires to move the car forward at a lesser rate than when I pushed the throttle forward for reverse.

I think there is an issue with the Castle Link V3.4 computer set up. I found that if I set the reverse setting to 100% and the forward setting to 50%, the buggy runs properly and when I set it to the factory default the forward and reverse power settings were opposite of what the Castle Link were. It might be user error, I will call Castle tomorrow and talk with them.
Anyway, what a difference it was from the first time I took it to the track. The buggy took off and was flying around like I had hope it would.

Thanks for your input.
