r/c boats use simple wedges to help lift 95% of the bottom of the boat out of the water. Why don't r/c cars use these? Chasis are not cheap. Wouldn't it be easier to replace a $3 piece of plastic once every 3 gallons then a $80 chasis? All it would realy take is a couple pieces of lexan plastic screwed in place where the buggy or truck scrapes the most. This way just that area scrapes, the cheap lexan gets torn up, not your chasis. The lexan is slicker then your chasis and slides better. Plus there is less chasis touching the surface so the vehicle is less affected by bottoming out. The hardest part about making your own sponson would be making sure that it doesn't scoop up dirt and turn in to a flap after a few hard landings. Yeah, putting something that sticks out the bottom of the chasis may make your car bottom out more, however it will also help to make the car more stable for those realy rough landings. It just might make a buggy faster on a rough track.

Tape your chassis plate or make a lexcen tray.

You could put a piece of plastic there but it would mean either raising the diff or losing ground clearance.

You can buy chassis protector already.... just a clear tough sticker that covers the underside of the chassis. When it's all scuffed up replace it.

Having plasitc blocks under there will mess up handling, landing from jumps... not help it.

There are a couple cars out there with plastic undertrays, but the idea hasn't really caught on with other companies.

A thin tray may not hurt anything. Take into account though that most cars have more up-travel than they do ground clearance; this makes the car much easier to drive.

I'm not saying that you should alter the geometry of the car by any means. However, a simple wedge in the middle of the car near the back and the front would both protect your chasis and also cause it to slide better when ever you bottom out. If it is in the middle then you don't have to worry about chasis roll causing the car to bottom out prematurely. It would be something simple like the front skid plates on most cars, that $2 piece of plastic. I'm also some what curious about the direction of 2wd electric chasis atm. Losi's current goal is to create a chasis that will roll better so that it can change directions faster. I'm pretty sure the reason kyosho built a chasis that resembles the xx-cr from the bottom is so that the car will have more room to roll.

There was a guy last year i saw had made 2 slider rails out of plastic about 1/8 thick screwed to the bottom of his kyosho777 they were trick and cut down on chassis wear to almost nothing.
