Hi, ive had a few redcats in the past but lost interest before i got really into them, but now my son has a volcano-16 i just bought him and at some point soon i want to make it brushless and make it waterproof, so in guessing a waterproof Motor, ESC, and servo would do it, but im looking on Amazon and dont know what im looking at/for, i would think installing them would be straight forward enough but i dont know which ones to get, i prefer amazon but would probably order from other places if need be, please help my son and i with making this upgrade happen, i dont want to be ordering the wrong parts, thanks
