Although I meant Lipo, you know.... Nimhs to Lipo = 100g lighter (depends on which saddles you use). Im tired, excuse me, im conusing myself.
But, if the motor was at the back, stick pack down one side etc, your unlimited with your choice of cells
Put all the heavy stuff further back, rear mounted rear shocks, and you should be getting close to the weight distribution of the X-5/XX4 which is a significant reason why they handle so damn well!!!!
