Whoa brother, you cooked that good!
You need to run the aluminum diffs if you want to have that much power

The plastic diffs can't hold the diff rings in place without twisting out and melting running that much power. The aluminum ones can handle a 4turn with 2s lipo no problem as I have run that setup in my TB03 no problem. Along with the aluminum diff upgrade I highly recommend getting ceramic diff balls as well
