Twin T-tailed gliders boosted together, much like the Geminee.
The kit contains:
I bought this kit from BMS at NARAM 45 so that I could build it in the hotel room and fly the next day. The instructions were a couple of 8.5x11" printed with illustrations of some steps. Rob tries very hard to make the kits go together, even if you throw the instructions away, but he did a really good job with the Twinsee directions. The parts fit together with the trademark Edmonds jigsaw-like alignment. There are 2 pieces to each wing, a stab, fin and fuselage for each glider. A neat trick that BMS has is the ability to laser score lines to aid in alignment of the motor tube on the glider fuselage. Very cool, and makes for a very easy build. One of the gliders gets the nose cone and the clay weight, the other is the motor holder. I think it took me about 20 minutes using CA glue throughout.
No sanding is required, and the CG is clearly marked on the wing of the gliders.
I initially didn't finish the gliders, but decided that I needed some higher visibility after the 1st launch. To that end I used a light coat of florescent orange spray paint on the tails of the gliders, since that was most likely going to be what was sticking up from the grass.

I don't have the instruction sheet in front of me so I don't remember if there was a recommended motor list. For the 1st flight I decided to use a B4-2 since it's a good overall glider motor. Prep is very easy... insert a motor into the motor tube so that 1/2" is sticking out the aft end, then tape it in place. Slip the other glider over the forward end of the motor casing and you're good to go. On the 1st flight I noticed the "upper" glider rotated around the motor (due to wind?) so the wingtips were touching. I avoided this on future flights by placing a piece of tape on the motor case to make a slightly more snug fit.
1st flight- very cool.. good separation of the gliders and they circled slowly, landing about 100 meters from each other. The B4-2 was a good choice.
2nd flight- A8-3 and the ejection charge fired with the gliders pointing down at a low altitude. They barely managed to pull out for a glide.
3rd flight- B6-4 and ejection happened nose down but much higher, a good choice.
4th flight- C6-3 boosted very high, straight and fast. The gliders started to circle in opposite directions and one flew for at least a minute.
If you plan on flying this model on C motors, have a good sized field and someone to watch one of the gliders. These gliders are really cool looking in the air. I think they'd be legal to use in B or C boost glide contests since the motor casing glides down with one of the gliders. You's just have to make sure the timers tracked the other one! I wanted to ask Rob Edmonds about making the gliders turn a bit to aid in recovery but never got around to it.

The Twinsee is definitely a cool rocket. Because it is 2 gliders in one, it has a high excitement value. As an Edmonds Aerospace kit, assembly is quick and gotcha free. Super kit and a super performer.
