A fellow named Mitch Amos once proposed a model made from two separate aircraft that would blast off as a single unit, then split apart to glide in individually. I agreed that it would be a neat trick, and the Geminee series is what I ended up with. The design is a pair of what the engineers call "tailless" aircraft, because they have no horizontal stabilizer. They launch in a symmetrical configuration, reach altitude, and are then blown apart by the motor to fly back down in a spirited, energetic glide. The repeatable laser cut parts again ensure that the builder only needs to add a bit of clay to each plane for nose weight, then the adjustments are complete.
