Stevens AeroModel Gym-E

Gym-E in flight

The Gym-E is a lightweight V-tailed 3-channel indoor/backyard flier, designed by Todd Long and kitted by Stevens AeroModel. It is a slow, predictable, and relaxing flier, perfect for touch-and-gos and tree slaloms out in the cul de sac in the still evening air.

Gym-E flyby

The Gym-E took about eight hours to build, of which four hours were spent covering. The covering is transparent Solite. The flight gear is:

The all-up weight of the completed model is 5.8 oz, including 0.25 oz of lead weight in the tail for balance, giving it a wing loading of 3.31 oz/ft2. With this setup, the Gym-E can cruise around at half-throttle for about 25 minutes on a charge.

I started building the Gym-E on 2008-12-28 and finished it on 2009-01-02. Its first flight was in a very small gym on 2009-01-03.
