For my kids bday I bought a new Traxxas slash 4x4 (1/10th scale). I bought the base model with a brushed motor, I think it is rated at +/- 30mph stock which is plenty fast for us. We have a dirt field and some hills behind the house to go blast around on.
These things do require periodic wrenching to keep them going. Its mostly cleaning debris from the joints and bearings, apply a shot of lube here and there, and check all the nuts in the right places.
I have run it through about 3 battery charges and 1 good crash so I wanted to dig into it a bit to check things out. The first thing I wanted to be sure of is the grub screw holding the gear onto the motor. It was tight when I checked it, but decided to pull it to add a dab of locktite. The gears were dry when I pulled the motor. I like to add a tiny bit of white lithium grease to quiet the gears down and keep things happy. You dont want to overdo it and get anything onto the slipper clutch, but if white grease finds its way there it should not do any damage.
The next thing I noticed is there is a bunch of debris getting into the driveshaft tunnel through the opening on the bottom of the chassis. That driveshaft tunnel goes all the way back to the slipper clutch so you want to keep stuff out of there. I got a small piece of foam to go fill in the gap between the shaft and chassis to seal it off a bit. It takes some tweaking and trimming, you want it tight enough to stay put but not too tight that it binds the driveshaft.
You can see scratches on the shaft where a small rock found its way in there. It made a pretty bad grinding sound
