I have a elctrix ruckus that i want to upgrade cheap but well.... I need a new body that is not electrix they are junk.. what will fit the ruckus? secondly i want to stay brushed can you suggest a brushed motor that is affordable yet fast and has enough torq for the big tires.. and 3rd i would like to make it waterproof.. so what esc could i get that will not tear up the transmission.. or if i stay with the stock esc what brushed motor would be a good fit? the esc supports down to a 12t motor so they say... Thanks for any help
