Well, went thru a 12S after the 1/8" shaft snapped, then snagged a 50mm 2200 kv medusa, and now I run that on 4s packs. Very nice, and very reliable. Got some 4S 30C 2100 Zippy packs for less than $40 and they freaking rock. Standing backflips easy if you are not careful. Also did the BB shock mod a while back as well. Essential. Led lights were removed in front until further notice. Bad crash damaged one and haven't fixed it yet.

35 wt in rear on HPI blue springs 71 gF/mm (from hellfire, slightly lighter than the LX1 yellow springs)
Got to race it against RCM Mike and Arct1k's .5s at the barn over the summer. Fun little race, but it was ran with the 12s. The medusa would have been nice for some extra punch, but otoh the setup was very light w/ align 140g 3s 2100 packs.

Also, the UTube link for
the 60mph vid got messed. A redo:
BTW, the medusa/zippy is just as powerful. Haven't done a speed run, but the feel is awesome. Love the motor.
ET Data on newest setup: 13/46 gearing on Medusa/4S and Masher tires. 90A peaks on a half spent pack and I was only dropping 2V (3.9V ->3.4V/cell) That's a 43C load!
