calling all losi 8ight T owners

My best guess is that he may need to use heavier diff oil so that the diffs don't unload as much, or he may need to shim the diffs for a better gear mesh, if the gear mesh inside the diff is too tight there will be a lot of friction, which will result in lots of heat. Maybe somebody with more experience could chime in but that's the only thing I can think of, unless there are binds in the drivetrain. He may need to use heavier oil too? Good luck finding a solution. I haven't heard of anything like this before so I'm thinking it has something to do with how he has his trucks set up.
