GALAXY

I've had 2 little micro cars..one was like a microsizer and this is some wierd brand that I'm not sure of but the first one did this too.I can turn the wheels backward by hand and its fine but if I move them foward it seems to click on every revolution.I haven't taken it apart yet because I want it to still work,lol....but I took the other one apart when it did that and could not find any reason why it was happening.I saw no sand in the gears or anything..no hair around the axle...the mesh was fine but it just would not go anymore so I gave up on it and got this one.

If anyone has one of these and has had a similar problem....any insight would be greatly appreciated.

Random general comments also welcome.
