Ok, I know this isn't the platform to really build a screamer out of, but I bought it for my 3 yr old so he's not toting my higher $ boats around the house and he'll have something to learn with. This is HIS boat, but you guys know how it is, I have to at least put a better prop on it and make it as fast as it can be stock. What are the recommendations??? BTW, it won't hurt my feelings if we burn up the stock components, so I won't mind being a little over-propped. Can the stock electronics handle 8.4v's Thanks!!
