Re: For Sale - (2) Four-lane K2 Timers

I would offer $100 max. for the newer one if you are interested. I am in the process of building one, but would defer building if you were interesting in selling at this price. Let me know in the next day or so as I am going to build this weekend, I already have some of my parts.

Best Timer for a DIY Engineer

I just ordered a 42 foot two lane BestTrack and am in need of a timing system. Was thinking about using a PLC but the scan time will most likely be too long. Any suggestions on what I should buy and / or build? I am open to either purchasing a complete unit or I can cobble a kit together. I also wan...

Wanted 42 Foot BestTrack

I live in NE Ohio (west of Cleveland) and would like to purchase a 42 foot single or double lane track. I am open to either a timer or no timer. If you do not live near me, I can pay for shipping. Thanks.

I put it on a tuning board with a slight decline, and with about the same axle / wheel prep as the current year 5 oz car, I noticed it was slower down the ramp than the...

Critique of Two Cars

My son built two cars (I actually did the cutting as I want him to leave cub scouts with all his fingers), but he did the rest of the work. I am attaching two photos and I understand neither of these is the optimal design but these are what he settled on - after-all, it is his choice - that is for m...

Maximum Theoretical Weight

I am entering an open race where there is no weight limit (it can exceed 5 oz). My question is, what is the point of diminishing returns due to friction? I once heard 10 ounces is the optimal weight, however, I am not sure. I am using stock BSA axles and wheels (all polished, etc), but am curious if...
