I don't know what "wot" means. It is only when you hold the truck in the air and throttle? Or does it happen when driving it? All the time? Only at low throttle/full throttle?

Can't really help you with the little info you gave.

I thought it was something like that but I just couldn't find the right wording.

So now we need to know if he's holding it or if it's on the ground running.

It does it while holding it in the air or on the ground either way, I also noticed that if I grab the yokes I can move the pinion back and forth inside of the diff almost an eigth of an inch

Just got mine I think mine is doing the same thing. I need to check the gear mesh but have not got into it yet. I just posted a VID up on my thread on here watch it to see if it sounds the same.

I just ran mine for the first time and it is pretty noisy. It sounds 'crunchy'. It doesn't matter if it's on the ground or in the air.

I had the noise in the beginning. It goes away after some brushless runs.

When I swapped my motor out I tested the drivetrain and everything rotated smooth and without noise. It's noisy running under power though. I don't worry about it, I just run the thing.

The noise comes from the driveshafts U-joint. I did some shaving it really helps.

The drivetrain in these things are just noisy. you can shim, shave and ballance all you want, but you cant get rid of it. shimming everything per the instruction manual supplement helped, but the noise is still there.

Also, after running it alot, it seems that th drrivetrain has "seated" itself, and has quietened down a bit.

Just 1 more thing to make this truck unique

It's really not that noisy. No louder then the E-Maxx.
