been chatting with Andrew this afternoon (Pioneer, my cohort in crime build), and it is one way of getting the motor underneath the rear deck, to go with a brushless motor as there isn't a great deal of space, and as the vspu's don't need a great deal of revs, and the fact that they only need forward motion on the motor......reckon it might be a good idea.. plus both units could run off small output/physical size motor each,and one esc between them.......it would help greatly the electrical wizardry set up.
