Many Questions...

I've been checking out these Auldey cars, and they look amazing. I have many questions, however. (probably because of the lack of info on these)

Can the 1:32 scale race-tin cars be run outside on a smooth street or driveway? (paved within the last year)

How hard is it to modify the car so that it can use the modified motors? I'm no good at soldering. The wheel mod too, is that difficult to do?

Which is better, the "bullet" control or the pistol-grip? Is the pistol proportional? I think that it may feel wierd using a pistol-grip that doesn't have proportional steering.

How easy do the stickers come off? They really look cheesy IMO.

The motors are pretty close in the speed that they say they're capable of. Which is the best? How fast do they REALLY go?

I figure that if these are as good as I think that they could be, and enough support and info was available on here, that a lot of people would buy them. The idea of a small R/C car that could be run outside, easily modded, and can go almost as fast as my 1/10th scale car (maybe faster?!) seems like the ultimate. Who wouldn't want one?
Sure the Bits are fun, but after my body cracked because it fell off the kitchen countertop one too many times I had second thoughts about how fun these could really be.

Hopefully my questions can be answered! I'm sure everyone could benefit from knowing more about these things.

Thanks,
Phil
