I have a Baja SS and there's no way really that I would even consider making it electric. Mine runs through mud, dirt, puddles and trees lol; all places where I'd be scared to put almost $3k worth of electric stuff near, at least not without some industrial strength waterproofing. Plus it sounds awesome, especially with a decent exhaust.

I don't really see how it can compare:

On a full tank of gas I get between 30-45 min of run time, depending on how hard I am on the throttle. I doubt those batts would be able to provide more than 20 min. Even then, you gotta recharge for an hour. You could spend an extra $400 on a second set of batts, but then you'd be through them also before the first set was done charging. You'd also need some pretty serious power supply goodness to charge em in the field.

When I run out of fuel, I just put more in and off I go again :D. No need to wait for stuff to cool down, or for batts to charge. Usually if I have to wait longer, its because I broke something :D

As for durability, its 6 one way and half a dozen the other. My Hyper ST is only around 7kg. The Baja is close to 14kg... Nuff said lol. I have hit trees, poles, done huge jumps and had crazy crazy crazy cartwheels, and so far the only thing I've broken is the plastic spur gear a few times. They're fine out of the box.
