Same for us. Just don't want to look like every other car. No other reason for using color wheels.

Re: leaving off the 4th wheel

If you're rules don't specifically state that you have to have the wheel then I would feel free to leave it off. Also, some rules say that you must have 4 wheels, but don't say anything about where the wheels need to be. If that's the case I would move one wheel to the top rear of the car (embedded ...

Re: How many is too many?

I have heard people say that you need to turn the canopy 90 degrees and put it very far back to have an aggressive COM (yet that would put the "stem" of the canopy right in the path of the rear axels). I see your canopies are rooted in front of the rear axels. http://i1262.photobucket.com/albums/ii...

Re: Team Topspin 2014 Line-up

I really didn't expect any of our cars to be that good.... let alone faster than last year. Especially the one under my name that I dropped mid-build. The top 4 cars in the race were ours. All the cars were set up pretty similarly and were not assembled until Tuesday night because of how much time I...

This is my oldest son's car. He won Bears and was overall pack champion (3rd time in a row) because his brother (who was blow'n the doors off the field) had 2 unusual bad runs at the end of the finals. Spoon like last year (ran best time of 2.966: http://i1262.photobucket.com/albums/ii614/topspin-d/...

Re: How many is too many?

Only 2 days left until the race. I'm trying not to neglect my own kids, but I'm getting pulled in many different directions. Unfortunately, the boys have not shown much interest in working on thier cars during the windows of time that I've had the last 2 weeks. They only want my attention when other...
