    Speed test with the Dewalt 820 14.4

    Has anyone done any speed tests with the Dewalt 820 14.4 motor with various pinion and spur gear combos. If so can you give me the speed and what combo you used. I have used all different size pinions from 11t to 21t with the stock spur gear. I just don't have the speeds. Thanks

    Ok nobody must have done any speed tests. Can I get an opinion on how much faster the beast is with different gearing. I run the 11t and it is slow for crawling, I also run the 16t and notice the beast is a little faster than stock. So if stock is 22 mph then I would guess the 16t is 25 to 28 mph. I had the 19t and 21t on a long time ago but I'm looking for how much faster the beast is. Best guess please.

    I had the dewalt 820 motor with stock 14/68 gearing. According to the Traxxas telemetry app I had a top speed of 19 mph. I tried a 17t pinion, and got up to 22mph, but the motor got way too hot.
