Propeller Powered
Pinewood Derby Car Kit







Introduction
Some organizations give parents and siblings an opportunity to race by sponsoring an open competition race. Typically the rules for these races are somewhat relaxed, oftentimes allowing power-sources other than gravity. Our Propeller Car Kit is a great fit for this type of race.

But even if your race venue does not permit cars with propulsion assistance, our Propeller Car will make a big hit with the crowd when ran as a demonstration between races. In fact, some cubmasters (and other group leaders) have used this type of car as a "challenge car" - "I'll bet you can't beat my car!". But regardless of the venue, the Propeller Car is fun to both build and race.

Description
The Propeller Car uses a ducted fan for additional propulsion. The car is powered by a 9 volt battery, and is started by a front-mounted switch. It also has a "kill" switch to turn off the car when not in use. The kit includes a pre-cut and drilled pine block, ducted fan, switches, battery holder, and the other parts needed to assemble the car. Wheels and axles are not included. Any pinewood derby wheels can be used, but for best speed we recommend our 4040-Outlaw Wheels & Nickel Speed Axles.

Required Equipment
You will need the following tools and supplies to complete this kit:
Specifications
Other than the non-gravity power, the Propeller Car meets BSA specifications for dimensions and weight (typical completed weight is 4.7 ounces). It will fit into a standard Go/No-go Gauge.

On a typical track, the Propeller Car will generally beat a standard, gravity-powered car by over 8 feet. On our 32 foot aluminum track, the Propeller Car completes the course in about 1.9 seconds; a fast, gravity powered car runs the same track in 2.5 seconds.

Options
The kit is equipped with an extended wheelbase, which has precision-drilled axle holes. The holes are drilled with a #44 bit to fit BSA-type axles, and are drilled 4-on-the-ground.

The following standard options are available:
