i have an idea but not sure if it will work
 

i was thinking if i raised the suspention on my f-150 and made like a cover for the bottom so it can run in dirt and on sand and gravel and stuff without it ruening my car, i was reading the instructions and it said its an indoor car only so i was wondering if it will work or if there is anouther thing i can do to stop the dirt getting in

there isn't much you can do to keep dirt getting in, believe me i have tried you would need to have any shielding very well sealed aganst the body and the wheelwells would have to be sealed also.

If you really want to subject it to those elements, i suggest u go to a hobby shop and get shielded bearing all around.

A can of compressed air will clean the dirt off fairly well.

But honestly, I thing these would be OK on hard packed dirt. There isn't much clearance for serious off-roading.

Although rock crawling on large gravel doesnt yield much debris, either.

Time to go find some...............

could also try and plasti dip stuff to helpwater proof it.

dunno if you can do it on these cars though. I know on my nitro car you could

water proof = dirt proof
