With NO rules whatsoever, how would you design a Pinewood Derby car? - bsa pinewood derby block dimensions
Our business is to have all the shops and construction of a pine forest of vintage cars (starting with the official game BSA) and career all at the annual meeting of the administrator. The only rule is no rules. Suggestions?

Bsa Pinewood Derby Block Dimensions With NO Rules Whatsoever, How Would You Design A Pinewood Derby Car?

To minimize friction. The wheels should be free to make and without vibration. Use the pen on the axes. be sure that the lines are not nails. whelels the body does not rely on the rail going all the way to the runway, the wheels should not come into contact with the body of the car. so that the tree must be constructed accordingly. Even if small for each wheel, it would be nice. or use the pencil point in the wheels, so if you rub on the rails is less friction. must be exactly horizontal and front to rear accurate measurements, otherwise the path is, it moves constantly. Weight helps some, but not too much or take too long. just my opinion, it contributes to the hope
Research or the creation of an aerodynamic fiberglass. Use a go-kart chassis, steering, wheels and tires. leave the system of functional disc brakes for braking parachute, awsome backup option. Bolt a comfortable armchair. The bigger beter
I want to build a classic car that is the length of the runway. Once I started, I was ready.
I want a computer and CAD software we use data and information from air friction over anything that might get the bulk of the performance of the car to apply
Place one of these model rocket engines and get there two traditions Scouts how to shoot.
I just want my Porsche 911 race, or my Top Fuel dragster, because there are no rules at all.
I strap-D model of multidimensional Estes rocket engines in a tube mounted on the car ...
* Geez, I do not think anyone can beat me the answer!
** In fact, only two things to help - reduces the aerodynamic profile and the friction between the car and train. Despite what is indicated below, the additional weight is not the car faster (Ask Galileo, the original pilot Pinewood Derby). Consequently, the aerodynamic design is reasonable to create and polish, polish, polishing wheels (rims polished using glass, if possible). The friction coefficient is probably more important than aerodynamics in this case because the profile leading edge of the small car and the speed limit issue.
And then there is always the Republic of ChinaEngine market ...
Since it returns no rules, Bottle Rockets from the tape to the upper corners, and I hope that things do not get blown out in the qualifying race.
denser, faster they go. Nice for him a teardrop aero dynamics, it is hollow and filled with lead shot. (or, if you're willing to go to toxic lead melt in a fire of charcoal and pour it into the car.) is a very heavy car to the aerodynamic air hunt competition. Shot lead at work, but put in there more if it melts. It also examines the dimples of a golf ball that they will even give better aerodynamics.
I, too, such as rockets and rocket engines, but if it just the right angle of the car, the track.
