While it finally let up (rain) enough for me to run the CRT.5 up and down the street for testing. I was running a half charged (3.9 volts per cell) 2s2p lipo, Mamba Max ESC/7700, 13T pinion and a 46T spur. I have about 50 feet of smooth road to use and I clocked it with a Bushnell speedgun. 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?
