It is OK but the 4 wheel drive is actually quite simple in that you have a single drive solution used 4 times, and the side thrust or end thrust issue is totally overcome by the wheel mounting solution to which the motor connects.Why I do think this concept would be a lot better, by powering individual wheels. If Icedstorm wishes to use more as a basher and ride over rough terrain wouldn't a single motor setup with a simple chain drive have fewer points of failure. With a dual or Quad motor setup you have double or quadruple the points to solder and make connections, and you would have to get a way to mix all 4 motors together which would cause more failure points. You would also have to ensure that the motor shaft isn't loaded by adding a support bearing, unless they design motor shafts to handle the side forces from the wheel. I think it would be far simpler to get a single motor and set it up as a chain drive to remove possible points of failure. Not trying to be rude and say your idea is bad, I'm just throwing out other suggestions.
EDIT: Whoops I typed before I read through all the posts, sorry about that.
Wiring does not need to be all soldered as connecting terminal blocks can make it easy to assemble and maintain!
Anyway it is a mute point as it looks like he is seeking a simple electric fun runabout so it has since been simplified!
Mind you the thought of doing 4 wheel burnouts is alluring!
Have fun!
