No conflicting information. Usually if you replace the hull, you will see a performance benefit, but the motors in those boats are not hobby grade so you'll want to get a different motor. I imagine the boat you have doesn't have water cooling so you should think about adding that. Ofcourse the new motor (any good one) will blow the stock speed control so just get a new one now. I'd be very warry of the radio system too. Once you have it dialed in with the new batteries you won't want to loose it due to radio problmes. That should get you started.
