Hmm, interesting points Latency.
The MicroSizers definitly hav the edge on speed stock. My MS can run circles around my Zap straight out of the box. hehe and given the steering right out of the box this wouldn't be a difficult thing hehe. But after fiddling with the steering for awhile it is better. I have simply been adjusting the steering lever underneath. i do think now though I need to get a different set of tires for it. That would help on my slick kitchen floor.
The controller is actually easier for my big hands to use. I could do without the clicking though heh. The antenna is annoying having to wind it back in heh.
But I did find that the Zaps and the MS drive much differently. The controlling of the MS took a little getting used to. Could be because of the speed. I have yet to drop the turbo motor I have in my zap.
And I will agree that the run time is a bad thing. The Zap does run longer. But neither of them runs as long as my I-Racer hehe.
all in all I like all the cars I have. But they are different. I have friends who don't like the Zaps but love the MS and visa versa. Me I like em all
