Hey all, I'm about to get a senton, and just want some last minute advice/ reviews from all of you guys on the BLX185 esc. I know that this guy has a built in fan, but I'm worried about dirt, rock, and grass. Will any of these effect the performance of the fan/ the esc if anything gets lodged into it? And if so does anybody have any good home-made solutions to keep all of the objects out of the fan? Thanks for the help!
