Hey guys, in a previous post I'd mentioned that I'd be running the car on hard packed sand and gravel. Turns out, the sand near my apartment isn't as hard packed as I thought at all. It's loose and fine. I took it out for 2 or so minutes once before a screw got loose in the rear suspension, so I just did that up and cleaned the car from any visible sand. Second run, 10 minutes long. It's an absolute blast and I love this thing even on stock tires. I take it home, much thorougher clean. I took a brush and got in all the tight places, but when I started moving the parts, like the open front diff (I should lock it) I could hear a grinding noise, obviously sand got somewhere in there. The steering system seems to be also somewhat messed with, spinning the ball joint connectors is sounding like sandpaper (literally). One of the rear shocks also hisses more than the other, which sounds a little bit like sand. The rear diff also hisses when I turn it which means there's sand in there too. Have I really screwed my car over? Sorry for the long post, I'm an RC newbie.
