I was thinking the same thing. But in that situation, I would have probably looked like a blithering idiot myself as I stood there calculating the cost of replacing the chassis and surrounding parts vs dealing with scalded flesh falling off my hands for a few weeks. In the end, I would have...

Yeah, in the image you attached of my screenshot the guy that posted the install vid from 11 months ago said he still thinks it's great.

I just got an email back from them about the motor mount and belt drive. Very quick response time. I think I am going to go for it when I buy the drivetrain stuff. They said they are in stock, but the website says out of stock.

Yead, those gears with the D hole are stout. Nice machining on those. If I decide not to do the belt drive, I am at least going to do the motor mount and gears there.

So a guy that has had his belt drive for almost a year replied to me. Oh, here are a lot of cool X-Maxx mods, but some stuff is out of stock. https://wforccustoms.com/

This guy has a good setup.

I think most of the motor flex would be resolved if there was proper tension on the belt. In the other vid I watched the guy put screws through the chassis on the lower mount because the belt tension was pulling the mount up. That is probably why this guy has no tension on his belt. The other...

Yeah, his belt is way too loose. But the motor mount is also moving. That seems odd, because if there were a pinion/spur setup on there he would be destroying them with that much slop in the motor mount. So I wonder if he has done something to his motor mount? The other vids I have seen on the...

I think the LiPo vented at the front and back. If the belt was putting out that much smoke it wouldn't have drove back to him at all. Maybe the fire at the end melted it and he thought that was what caused the fire, instead of the other way around.

The title of that vid doesn't make sense. It was a LiPo fire. Not sure why that would have anything to do with the belt drive, unless the belt melted and burned the LiPo. But the video auther seems to only know the word "fire", so not sure what happened. But the truck was still able to drive...

If you want to try it, I could design a bracket to mount under the chassis to put nuts on that lower plate that holds the lower pulley in. I would definitely upgrade that plate to the Hot Racing aluminum one though. Heck, I might even do that upgrade with the pinion/spur setup.

It would be a lot less stressfull on the drivetrain also. With gears you have the gear mesh causing a very slight gap that will cause the gears to slap together. Not really noticeable, but it is there. Also, any bind in the drivetrain, as when the tires have a lot of traction in grass, slicks...

That is a good point. Although, it does look like a good system. I think it could be made to be very reliable. The problem I see in the motor mount design could create problems for both systems. Less so for the belt drive because a motor loosening up won't typically destroy the belt. It is the...

The only problem I see with it is the belt tension trying to pull that lower pulley up out of the chassis. In that vid the guy puts one bolt through the chassis with a nut on the bottom. I would do at least two bolts like that if I did this mod, if not all 4 with a 3d printed plate to mount...

Since you don't do any really heavy bashing, I would just stay with the pinion and spur. The advantage would be if your motor moves it isn't going to destroy the gears. That and it probably runs a little quieter. But I don't like the way the motor mounts on the X though. Those vertical slots...

Interesting. Never knew that was an option.

If Stoner can check his you can at least set it the same. But I am willing to bet it varies from kit to kit depending on which kid put it together 😜

Just looking at the diagram, that is basically a servo saver. So it would be whatever your preference is and depend on driving conditions.
