New to this forum and am looking for tips since this was our first year. My son's and daughter's (sibling race) first pinewood derby cars. Hers was a three wheel rail rider with 1.0gram wheels. My son's was a two wheeler with stock wheels and a stock nail in the rear. His beat hers. Unfortunately, his broke while playing with it after the race. We are rebuilding for the district championship race in two weeks and will use the good wheels this time. Honestly didn't know if it was going to work the first time so didn't want to waste expensive wheels.

All constructive criticism and recommendations are welcome.

That two-wheeler is pretty crazy looking! How exactly does it fit onto the track?

I'm guessing that they have an older brother or sister or two that have already gone through this... If not, those are some pretty incredible first efforts.

Is the two-wheeler design legal for the district race?

Vitamin K, it follows the same concept as a three wheeler as the front wheel rides the track divider all the way down. Here is a link of the car before body work. For reference sake, this is a 1/2" slope over 10 feet. Since the first car was destroyed at the end of the first race due to my son enjoying it and playing with his friends after the race. We are rebuilding for the District Championship in two weeks. I will videotape some runs

Thank you for your comments.

He has an older cousin that we helped out for a couple of years before this race. We learned a lot those two years.

As far as it being legal, I don't know. Since we are rebuilding anyways, due to the first car being destroyed at the end of the pack race, I will build the new one with the wheels much closer to the track than this design. I will let you know what they say on April 22nd.

Here are some initial pics of the rebuild with a few lessons learned integrated into the design.

That's pretty dang cool! Any trouble getting people to stage it correctly? Does it ever flop over and end up sliding on its side?

It did happen once where it flopped on its side after the transition area (the curved portion). I "think" it was because my center of gravity wasn't perfectly centered on the centerline between the running wheels. I have tried to improved the design by ensuring that CG is perfectly centered 1" in front of rear wheel.

On a standard Best Track, it looks to me that the stop section would simply tip it over as it rocketed off the end.

That is a very cool car! Way to think out side the box. I think with some modifications you could make it a contender. The stop section would be a big obstacle to over come. You should send it in and see how it does on a National level. We would have to make sure that it contains itself to it own lane though. Guys would not be happy to have that take out their cars.

Quite possibly the coolest car that I have ever seen.

Nice work!

They probably wouldn't mind as much if everyone was racing on two wheels.

This sounds like it could be legal for a street pro race with a guide pin attached to a front bumper for staging and tripping the scoring line.

I kind of want to build one but I'm too new in league racing to know if it was me or the design that made it slow if it lost.
