Long story short...One car in our recent pack PWD got by the inspection process with an extended wheel base. Our rules say 4 3/8". The kid got through with a wheel base at least 1" greater. How much of an advantage was that for the kid's car? FYI- I was one of the inspectors  Too many kids in line and we had too much to do!! I know weak excuse. |

every car is unique but.... definite speed advantage !  Our pack uses a GO...NO-GO guage wooden template / box to set cars in...instant check of overall length and wheel base/location (slots for the wheels to set in) no measuring needed--- it fits or you don't race   |

Do you have a picture? However, sounds easy enough to replicate.
I feel bad. We did what we could given the time, but there was just too much to do.
I have a feeling that this will be picked up during inspection of the District race.

People make mistakes. I have seen a few fast cars with short WB in classes where extended was allowed here at pddr. So if his extended wb car was not set up right then there would be no advantage. Did it win the race?

If they moved the rear axle back they had an advantage.... |

My son raced in the recent 65 car District race in the Wolf division. The one car that beat his car was an extended wheel base car (wheels at the extreme ends of the car). It shouldn't have qualified under the rules, but I know it happens.
I think the advantage of the extended wheel base is two-fold.
1. Added longitudinal stability and
2. Greater latitude to move the weight further back for more "horsepower".
If you take a car with a standard BSA wheelbase, and change nothing except the location of the wheels and axles, the only advantage would be added stability (which might even be offset by moving the front wheels forward more than you moved the rear wheels back!). BUT, if you also moved the main weight back to again achieve a COM of, say, 7/8's in front of the re-located rear axle, then this would be a significant advantage.

W is right. Sounds like you got beat by point #2.

All good stuff. I don't think they read that part of the rule and it got by us because we were so swamped at the check-in. They are good people and I doubt it was intentional. I worry that the car now won't make inspection at the district race.

I considered that, but looking at the design of the car there is no way for them to relocate the axle hole. Especially b/c our district holds on the cars so people don't work on 'em. Based on that, I have deicded to not say anything and hope they get in the district race. If they get D'qd the fourth place car will get to go.

Getting past inspection is easy to do in BSA Pack races as most of the people handling the registration/inspections are volunteers and don't know what to look for. Someone has to physically show them what is outside the rules. Sounds like you knew what to look for but your attention was drawn elsewhere. I've also witnessed scout leaders make last minute exceptions so a scout could race his car. Most of the time this isn't a problem if the violation in question doesn't give a significant advantage over the other cars (e.g. height violation). The extended wheelbase definitely gives you an advantage but how much is debatable as other things have to done properly to take advantage of longer wheel base. Case in point, if you watch the PDDR race videos you will see cars with a standard wheel base outperform cars with extended wheel base quite often. I know MB built one last month that kicked my rear. Wasn't even close  |

I agree. I think everything will turn out good in the end.
