Re: Design Judging Article

Maybe this is just my bias as one of the dads whose kids usually lead the pack in speed, but I think disqualifying speed winners from design judging is kind of wrongheaded. Yes, I get that you want to distribute the trophies to more kids, but really, if the kids won, they won. Why penalize them arti...

Re: Brand new to forum and pinewood derby

http://i66.tinypic.com/jq6o83.jpg Above is the track I just built. Cost me about 80$ in materials, and about three hours of time. Never built one and seems to work good. Just need to add starting gate and timer. As you can see my basement is a war zone of kids toys. Pretty cool! I envy your basemen...

Re: Best timers for use with GP Race Manager

Our Pack Timer (an aging Smartline) has fritzed out on us in the middle of a race again (reported accurate finish order, but not accurate times), so I feel like it's time for our Pack to consider a new timer. That could have been a start switch issue. The SmartLine\Champ timers will provide times r...

Re: Best timers for use with GP Race Manager

Howdy, Of course, Micro Wizard and the Champ are wonderful timers because they have all those really neat areas where they show the Elapsed times that people love. They're probably not going to go out of business real soon either. However, I also know what they cost. The Judge timer might be your b...

Re: Aggressive COG limits

Hi Vitamin K. I'm restricted to 4 3/8" wheelbase and using stock slots. Car ran 2.533, and 2.516 on a 35' best track with champ timer. No wiggles in those two runs. Aluminum track seems to be the track we are and will be using. Given the previous stats and measurements from the previous posts I gav...

Re: Aggressive COG limits

Hi Vitamin K. Thank U for your input and valuable insights! Let's say we are on a best track. Decently set up with good seams. Rear is balanced left-right and aligned properly. 130.5g in rear and 12.5g on DFW with 4.5" of drift in 4', theoretically. Is that pushing limits for BSA stock materials? W...

Re: Aggressive COG limits

The track matters too. Not only aluminum vs wood (the smoother the track, the more aggressive your CoG can be), but also the shape of the curve. The curve of a Besttrack is a lot more brutal than that of a Microwizard. A lot of cars come out of the transition with some serious waggles on the former.

GPRM v17, UX suggestion

This is minor, since I think most people probably just import from spreadsheets, but... In the registration screen, when you're entering a racer, it would be nice if, in addition to just a "Save" button, there was a "Save and Add Another" or maybe just an "Add Another" checkbox to tick, so that it w...

Re: GPRM on Linux?

Ah well, bummer that. Thought I'd ask.

I find Wine to be so fiddly, it's usually easier just to pop open a VM. :)

GPRM on Linux?

So, it looks like the latest version of GPRM is built on PyGTK?

Would it be possible to create a build that runs on Linux? Even an unsupported version?

Would be nice to be able to view/edit race files without needing to spark up my VM.

Re: Brand new to forum and pinewood derby

Hi Sloroller, welcome to Derby Talk! It really sounds like you've done a lot of homework, prior to your son's first build! Congratulations on your wins! I don't know that anyone could guarantee you a 3.0 or less, since tracks vary a lot. That said, I'm sure we could offer advice. Maybe a good starti...

Re: Starting position for rail riding.

Good question, and I don't have a good answer. This might be a good one for some of the league racers who stage 100's of cars a day for a race.

Re: One half inch Center of Gravity

On a smooth track with a good rail-riding alignment, 1/2" CoG is pretty standard these days, I'd say.

Re: Graphite on wheel tread

The only time I'd want a slippery tread is if I were building a 4-wheel-touching rail rider, and I wanted minimize the traction of the 4th wheel as much as possible.
