Mostly run them on loose surfaces like snow, dirt... and some off road serfaces like rocks, grass weed's, ect. They work on road, but they tend to make everything get hot. If you want to run your non-brushless pede you just need to cover the esc so no water get in, then you need to eather cover up or water-proof your sevo and receiver. Keep in mind that the pede is a light 2wd car and to get any kind of traction your going to need tire chain's or big pullers. Your motor is fine because its basicly waterproof anyway. Make sure when you get in from that bashing to dry everything off, then put it upside down to make sure the water gets out of every nook and crany. You might also think of getting some alum. screws from 'hex screws' because they wont rust. Best of luck,
