vids.myspace.com/index.cfm?fuseaction=vids.individual&VideoID=7137596Link to a video of the track we are using at district. A lot different than the one my son just won the pack race on. Much smaller drop down, probably equal length, with a long flat run at the bottom. Manual release. Now, our car's balance point is 3/4 of an inch in front of the rear axle, extended wheelbase, 2 full ounces behind rear axle, I believe 2 ounces about 1 1/2 in front of rear axle. wheels float on the axle heads nicely. Is there anything different I should look to do, or will this car be able to muscle down the track fast enough? Thoughts?

A long time ago some gave me this tip: Alignment! Alignment! Alignment!

A long time ago some gave me this tip: Alignment! Alignment! Alignment! Thankfully our alignment is darn near perfect, if not perfect. Car runs straight and smooth, no wheel noise. It's a winner for sure, hopefully on the district level as well. Thanks for the advice  |

fatdaddy, at least you know what you'll be racing on. Check out the response from one of the race officials for our upcoming district race in April. I basically asked what type of track we'll be running on: As in years past, we will have a varied collection of PWD race tracks supplied by volunteer Pacifica Packs. Last year we had some wood and aluminum constructed tracks. Almost all were either 3 or 4 lane tracks. They generally are between 35 and 45 feet. We generally have a different track for each Cub Scout Rank.So it's very likely my nephews will be running on different tracks as one is a Tiger and the other a Bear and we won't know until check-in! I guess I'll just leave the cars as rail riders and hope for aluminum. How many racers are they expecting? Our district brings in 300 cub scout cars, not sure on the number of webelos as they run separately, they all run on 1 4 lane track, double elimination. So only one winner from each heat advances in the winners bracket, the rest go to the losers bracket. I'm hoping our non rail riding machine will do well on the aluminum, but I am obviously nervous. |

Is there anything different I should look to do, or will this car be able to muscle down the track fast enough? Thoughts? My 2 cents. You have an aggressive set-up that will work on a steeper short track. That much behind rear axle may not work on this track. I would be inclined to push COM up a little, closer to 1" for performance on the long flat. Good wheels will get you off to quick start. Track seems smooth, but never hurts to hedge your bet and turn it to the rail a tad. |

At 300 and 3 cub scout ranks, that would be 100 packs in your district, seems like a lot. I didn't ask how many usually particpate in our district. Not necessarily. 8 scouts from each pack go. This year in our pack, 7 of them are below webelo, we only have one webelo going. It's usually at least 2 per rank level per pack that go, though each pack does it differently. |

My problem is there isn't much place left on the car to move the weight, and all of the weight is epoxied/painted in. Unfortunately I think I may not have a choice but to leave it as is, maybe steer it to the rail (which I am still reading on) and hope for the best. Next year I will know better what I am looking at, and since the rules don't prohibit it, maybe make a second car for the district race. |

your car is set up fine! 3/4 in front on an extended wheelbase is good. MAKE IT A RAIL RIDER! i am assuming it is a 3 wheeler, if so a good set to the rail and you will roll!

Actually, it's a 4 wheeler. I wasn't so sure about the whole 3 wheel thing, so I figured I would look into it next year if he got beat by someone with 3 wheels. The boy who came in second behind this car was a 3 wheel. All great ideas I'm going to look into for the next season, assuming we get beat like I think we are going to. Again thank you for the input, it not only helps my outlook for this year, but for the next as well. |

Four toching and "alignment is darn near perfect" you are doing something right! Or you sleep with the angels.  Don't touch it. Best of Luck in next round. |

I would say it's not the sleeping with Angel's I think we just got lucky with a great alignment. I'm hoping he cracks top 5 in district, it will give him somethign to build on for next year, but no complaints if he wins it all |
