The thing is, the motor can chuck out 4,500W (very roughly for a short time period) if it *needs* to, to achieve a certain speed (like to get those last few mph out if it hits over 140). For most of the acceleration curve the motor will suck quite a bit less current as it's under less load, making less power as a result. I should be able to use some programming tricks on the React to get acceleration a bit more manageable, and the F103GT can take a variety of 48P spurs. The tyres will spin before a spur strips, so that shouldn't be an issue. :)
By the way, the motor pod plates have been re-designed a bit to lower cost (Metal Man, you were right in saying I should enlarge the radii lol) and also to get rid of some mistakes in my design lol:
