One of the fastest and fun boats to own. It faster and larger than some 600 USD boats. High poential in upgrades. The electronics like the servo is good enough, it could be stronger and faster. Its completely water proof, we had the canopy open and water go into the boat for 2 hours when we were trying to recover it. Still works! Lots of foam in the nose so it will never sink. The only compaint is the canopy can open after a hard crash. You need to do the mod that uses thumbscrews for front and rear and the problem is solved. Battery placement is also important. make sure to the velcro to prevent the battery from sliding, because if the battery is not placed correctly it will not roll over if upside down. I perfer this style of roll over tech, its a lot faster than the water filled flip over tech and I find it more reliable.
