It was averaging about 35mph at the end of my 50 foot run. I made about 8 runs and the temps were: Motor 85 degrees, Battery 72 degrees and the ESC was 109 degrees. The temp outside was 68 degrees. Seems the ESC was running a little hot. I will try lower gearing (12T pinion) but it looks like it is going to start raining again.
Can somebody confirm that I should go lower on the Pinion (go to a 12T from the 13T) to bring the ESC temps down?

With the 7700 you will probably need a 10 to get the temps down. Are you running the stock buggy tires or larger truck tires.
