About 3 minutes into drifting the motor was around 200 and the ESC was 135. After I turned the fan on, 2 minutes later the ESC was down to 100. I believe the stock pinion is on this thing. What should I drop her down to? I just counted and it's a 28T pinion rather big is you ask me. I'm thinking drop it to a 19T? How's the sound?
