Have you found any upgrades for this boat? I just recently got one and not long after the esc went out so i put tue one from the airplane they sell at harbor freight in it. Is there any where to order factory parts for it also? I cant find one online anywhere!!! But my most emediat question, do you know what size props ill need to order for it? Thanks man. This boat has been a bunch of fun. Im just trying to keep it going.
