Wow, I knew in the back of my mind that the Vectrix was "heavy", but it wasn't until I just started comparing stats that I realized quite how heavy!
The Vectrix is almost TWICE the weight of an XM-3500Li. The V is 515 lbs vs. the XM at 275 lbs.
So, here's what I think we should do - put the Vectrix motor into the XM. That should be fun! ;-)
Feel free to flame away (this is, after all, a friendly dig!)
