The gaping hole in the side of the ESC freaked me out while carrying SP140 on the back of the car down dusty roads, so I created this dust cover. It also stabilizes the flimsy throttle plugs. It’s press fit between the mounting bolts of the ESC. It’s been solid through multiple flights, and the plugs would have to come out of their sockets for it to come off of the ESC, so it’s safe as far as I can see. Easily removable as well.
A cover for the entire harness and frame is impractical as it will make a giant drag chute while driving… and it’s pretty difficult to seal up the entire unit in a bag. BUT, I do use an Ozone Sombrero to cover the entire thing while it’s sitting out in the desert if i’m leaving it out all day while camping to keep the sun and dust off.
But I do put a cover around the motor. Took a draw string bag made of ripstop and sewed it the right size to fit tightly around the motor while driving. The ESC itself is otherwise pretty sealed up.
