I think I will order a 4 pack of the LXX's, I guess they can be used for parts worst case, but from what I'm hearing cruising the boards - they are not too terrible. I guess calling their stock motor a "3.0" is a marketing gimmick. I am finding that the motor color codes mean very little with these clones. The red or orange, or is it reddish orange motors that came with my other motors are pretty quick - but I don't have anything else to compare them to. I bought a couple of Hot Wheels KIT racers with the Tomy yellow and orange motors, but haven't had the time to try them out. The crip-cap doesn't bother me because we tend to keep them close when we are racing them. Both of my clones are only good for 10-12 ft before they stutter.
I'll probably buy more of the KIT racers for their motors and batteries, so I will have 4 cars that are identically equipped for my future miniature speedway. All I can say is, my family is having a total blast with these things on a hardwood floor!
