    Exclamation Erevo sudden braking problem. Help needed

    Hey all, my ERBE has been annoying me lately. After changing the pinion to 21T and spur gear to 54T and also changing the radio to a FlySky GTB3, I noticed sudden braking with the truck.

    I used the castle USB link to reduce the braking power to 40% on the ESC. I've also loosen the slipper clutch and I'm still having the same problem.

    I'm running 4s lipo with onroad tires and it's fast but when I apply brakes, the truck just stops suddenly and flips over. What should I do?

    I had to turn my brakes down to 25% on my revo, and every once in a while it still flips on grass though. What gearing were you using before? The Mamba system has a lot of power and that includes braking power so you may just need to make more adjustments and check the settings on your radio. I am assuming you reprogrammed the esc's endpoints to the new radio.

    You need to adjust your brake curve. Here is my complete setup from my 4s days., you can adjust as needed, but I find that it does quite well on very high traction surfaces.
