Electrathon is a fun and challenging form of race/rally competition combining vehicle design and construction skills with driving strategy. The rules allow for a great degree of design variation, but stress safety and low cost components. Battery and driver weight is regulated to ensure close and equitable competition.

Seventeen years ago Blue Sky Design LLC took on the challenge to develop an American designed Electrathon racer to compete with the state of the art Australian Electrathon vehicles introduced to the United States by the Australian champion Clark Beasley.

The result was the award winning Aerocoupe racer. The Aerocoupe has become legendary for its low center of gravity, stable balance and efficient aerodynamics. It has proven itself as an attractive and affordable design that is light, rugged and fast. A versatile performer on both fast and tight courses that is easy and fun to drive.

Today the latest M series Aerocoupe is the most popular Electrathon racer in competition all across the country, available as an easy-to-build kit that can put you in the drivers seat of a race proven winner.

As a leading supplier of vehicle kits and components to schools and individuals, Blue Sky Design LLC has established an enviable record for quality, prompt response and customer service.

Quality motors and electrical component packages for the Aerocoupe M series kits are available separately from our list of reputable suppliers.
