The lowered sides need to be clear of the sides of the rail so that it does not drag on the side of the rail. This usually means that they need to be outside of the inner edges of the wheel treads.
Otherwise, nice job ... really nice job!

Re: weight advice---pic
If, in fact your CM's are/were 0.62". Measuring CM by balancing is difficult and more error prone than measuring by weighing and calculating. I would consider wheel weights as "barbell" only in the side-to-side CM location (CMy). CMy has small role in the apparent lightness of the fr...

Re: weight advice---pic
Differences between cars with identical CM but different arrangements are "lost in the noise." I've heard of no one who has produced experimental results that "barbell" weighting is inferior to "concentrated" weighting. Nonetheless, I would concentrate ballast to the e...

Re: Minor weight question...
Major flaw in that it allows the two fastest cars to race the second time prior to the "final". Easy fix: Label 4 buckets Run, 0, 1 and Out. Collect number slips into bucket 0 (0 losses). Round 1: Empty bucket 0 into bucket Run. Proceed as before from bucket "Run" except that eac...

Re: Minor weight question...
Last year at District, he would've had a solid 2nd place finish, but as chance would have it, he had to face the eventual winner twice in early competition (2 lane track, double elimination based on random draw per round), and both races were "too close to call" with the eye, and he was &...

Re: Minor weight question...
Which kinda sucks, because if he does good, we go to the district track, that is long arc/drop & short straight with center rail and no side rails. Won pack races, but never better than 3rd on the district track. Okay, you already know how to do well on your pack track. Let's focus on the distr...

Re: Opinions Wanted: Critique my Rail-riding explanation
Hey - question for you guys on rail riding. Why such a huge drift? I've been reading on RR and most are saying 3-5" over 8 feet. Thats huge, basically as soon as it leave the block it runs into the rail I'd think at that amount. Why not like .5" over 8 feet so it has time to build up spee...

Re: Minor weight question...
Most builders report that extreme rear weighting performs better on short tracks (28'-32') than on longer tracks (38'-48'). I understand that this is a trade-off between initial velocity on short tracks and DFW friction on the longer tracks. The cause for DFW friction is that greater toe-in is neede...

Re: Outlaw Derby
Think about the likely participants ... how "hard core" are they? Do you want to allow other than BSA wheels? There are some fantastic, really low inertia wheels that can be made or bought. What about hubs and axles? Will you allow roller bearings and/or needle axles? Do you allow "no...

A relatively easy and long lasting mold can be made from two 2' of 2"X1/4" structural steel angle iron. 1. Place together to form a T when viewed from an end; 2. Clamp together; 3. Near each end, drill 1/4" holes and bolt the T together; 4. At each corner of the top of the T, drill a ...

Re: Which one?
Elimination racing is in the class of "adaptive scheduling" which does not lend itself to a high degree of "lane and opponent equity." The best (I think) that can be done there is to insert a degree of randomness plus a follow-on attempt to achieve some degree of equity. For a fi...
