Re: Rotational Inertia vs Wheel Weights

I am not an engineer so I got lost somewhere in there but the COF for the car should be around .1 for a good lubricated car. If you want to play around with different things like this then download the Raceit software. This will let you set up your track, car and wheels and test what effect differen...

Re: BestTrack reviews?

How much drop do these aluminum tracks have? (Distance from starting pin to floor - Distance from flat track to floor) Also, do you know the angle of the decline or the distance from the track surface to the floor at the upper curve joint? I am trying to define the Aluminum BestTrack for use in the ...

Re: Totally different track at district race than normal tra

The type of track guides you describe don't seem like they would work well with the BSA wheels because they have the raised lettering on the outside. Wheels with out raised letters would probably work better with these guides. If the rules don't allow this then I don't have any good answers.

Re: Eligibility

Last year our District took the top two scouts from each group in the Pack(Tiger, Wolf, Bear & Webelos). In our area all scouts race their own car so we handeled it like the later statement. If someone could not race at the District event then the next person in that group was invited to take th...

Re: Groups, Subgroups, and Racing

I have the new version so I don't know the difference between yours and mine. But here is what it sounds like you want to do. Make the file name = "Pack 2000" Make the Groups = "Tiger", "Wolf", "Bear", "Webelos" Make the Subgroups = "Den 1"...

Race Issues

I ran a race about a month ago for the girlscouts in our area and this was their first race. It was also my first chance to test our new GPRM 4 software. The software worked great and has more options than I thought based on playing with the Demo version. There were 40 girls in three different age g...

Commercial Track Dimensions

Does anyone have the track dimensions for any of the commercial tracks that can be used in the Derby Sim Program. I am looking for data on a 35ft or 42ft Best Track Aluminum track but will take any other data you have. I know Derbyworx.com has some good info on both Best Track and Piantedosi but som...

Re: Check in / Inspection

Sorry Guys, I missed your request for the drawing until today. PM me with an email address and I can send it to you. I have it in AutoCad 2000 or I can send it as a PDF file. Caveman826, I like your fixture better. The plexi-glass lets you see the car better when it is in the fixture. I think I will...

Re: Check in / Inspection

I made a box up last year but I lost it while helping at the district race. I made a drawing for it and can pass that on. The open ended box was made with 1 x 4 cut down to 3" (our max height). The internal dimensions of the box were 2 13/16" x 7 1/16" to check the 2 3/4" width &...

PPN Charts / Sterns Charts ?

We have a 3 lane track and most of the PPN charts are for 2 rounds (6 races ea.) once you get above 25 racers. I would like to get some charts for the 25 - 40 racer range that allow for about 3 PPN rounds (9 races ea.). I want the kids to be able to race as much as possible for the work they put int...

Re: Axle Head

I have noticed that you can slightly reshape the axle some with the Pro Axle Press. I am probably tapping to hard with a big hammer. I always mark the end of the nail with a extra fine sharpie so I know what side of the axle goes up. I found that when I ended my tapping with this side up, the axle t...

Re: Inexpensive Trophies

I got trophies from this place last year. The ones I got were cheap plastic but they looked good. I had one broken piece in the shipment but they sent me a new one right away. I will use them again this year.

Re: Making a VW Beetle

I did a search and found the link to the "Old Style" Beetle and listed it below. I only made a template of the "New Style" Beetle in Cad but if you still want that then I can try to convert that and send it to you.
