Well, our district is definitely having an Outlaw race this year! The District scout race will be in the morning on 4/4, and the Outlaw race for the dads will be that evening.
The rules:
use the BSA block, wheels, and axles.
8oz. limit.
That's it so far. They might add some rules, but that is what the rules were last year.
All of my design ideas have centered around a thin car with 3 on the ground, but I'm not sure how to build a 3-wheeler for an 8oz. limit. Should I just scrap the "thin is in" mantra and go for a car that is at least 1/2" thick in the rear? What would be a better use of weight? Tungsten cubes or the cylinders (or the disc)?

Tungsten plates! Pesonally, I think once you get above 7 to 7 1/2 onces, you will see diminishing returns. We run a 8 oz. class in RAs and I have cars this year that are 5 oz and faster than the 8 oz cars we built last year. Scott |

I too have seen a finely tuned 5 oz. car beat cars as heavy as 1.5 lbs. with ease. Now if they allowed bearings, I would say the results could be different. Using the nail axle and BSA wheel only allows for so much weight before they just become friction robbing machines! Thanks Andy Lester Florence, Ky www.mpp-models.com |

I agree as well. One year we pulled the weight limit and had cars up to 12onces. But my 5oz car this year smoked the fasted heavy cars. 5-7 oz cars maybe the very best balance without using bearings.  I can only speak from my experience. |

I think it depends on how you place the weight and where. I would try 6 oz on the rear and 2 oz on the front., 15 to 16 cubes behind the rear axle, the rest forward. 1/2 thick body.
balance point of 7/8ths.
I would do 2 rows of 5 cubes behind the rear axle, with the remaining 5 to 6 cubes on top, perhaps 3 on top of each row.
forward of rear axle, it would be like, 3 rows double stacked until weight achieved. 8.2oz
