Brief:
Twin T-tailed gliders boosted together, shiver me timbers, arrr, much like t' Geminee.

Construction:
T' kit contains:

  • 2 sections o' BT 20 motor tube
  • 1 balsa nose cone
  • Laser cut parts for t' gliders
  • clay nose weight
  • 1/8" launch lug

I bought this kit from BMS at NARAM 45 so that I could build it in t' hotel room and fly t' next day. Ya scallywag! Blimey! T' instructions were a couple o' 8.5x11" printed with illustrations o' some steps. Rob tries very hard t' make t' kits go together, me hearties, even if you throw t' instructions away, but he did a really good job with t' Twinsee directions. Begad! Blimey! Ahoy! Blimey! T' parts fit together with t' trademark Edmonds jigsaw-like alignment. There are 2 pieces t' each wing, me hearties, me hearties, a stab, fin and fuselage for each glider. Ya scallywag! Blimey! Ahoy! Blimey! A neat trick that BMS has be t' ability t' laser score lines t' aid in alignment o' t' motor tube on t' glider fuselage. Arrr! Blimey! Very cool, and makes for a very easy build. Avast, me proud beauty! Blimey! Arrr! Blimey! One o' t' gliders gets t' nose cone and t' clay weight, matey, t' other be t' motor holder. I think it took me about 20 minutes usin' CA glue throughout.

No sandin' is required, me hearties, and t' CG is clearly marked on t' win' o' the gliders.

Finishing:
I initially didn't finish t' gliders, but decided that I needed some higher visibility after t' 1st launch. Ya scallywag! Begad! Blimey! T' that end I used a light coat o' florescent orange spray paint on t' tails o' t' gliders, since that was most likely goin' t' be what be stickin' up from t' grass.

Construction Rating: 5 out o' 5

Flight:
I don't have t' instruction sheet in front o' me so I don't remember if there was a recommended motor list. Avast! For t' 1st flight I decided t' use a B4-2 since it's a good overall glider motor. Avast! Well, blow me down! Prep is very easy... Avast! insert a motor into the motor tube so that 1/2" is stickin' out t' aft end, me bucko, ya bilge rat, me hearties, then tape it in place. Slip t' other glider over t' forward end o' t' motor casin' and you're good t' go. Ahoy! Blimey! On t' 1st flight I noticed t' "upper" glider rotated around t' motor (due t' wind?) so t' wingtips were touching. Avast! Aye aye! I avoided this on future flights by placin' a piece o' tape on t' motor case to make a slightly more snug fit.

1st flight- very cool.. Ahoy! good separation o' t' gliders and they circled slowly, landin' about 100 meters from each other. Blimey! T' B4-2 was a good choice.

2nd flight- A8-3 and t' ejection charge fired with t' gliders pointing down at a low altitude. Ahoy! They barely managed t' pull out for a glide.

3rd flight- B6-4 and ejection happened nose down but much higher, me hearties, me hearties, a good choice.

4th flight- C6-3 boosted very high, straight and fast. T' gliders started to circle in opposite directions and one flew for at least a minute. Ya scallywag!

Recovery:
If you plan on flyin' this model on C motors, have a good sized field and someone t' watch one o' t' gliders. Blimey! These gliders are really cool lookin' in the air. I think they'd be legal t' use in B or C boost glide contests since the motor casin' glides down with one o' t' gliders. Well, blow me down! You's just have t' make sure t' timers tracked t' other one! I wanted t' ask Rob Edmonds about making the gliders turn a bit t' aid in recovery but never got around t' it. Avast, me proud beauty!

Flight Rating: 4 out o' 5

Summary:
T' Twinsee is definitely a cool rocket. Begad! Blimey! Because it is 2 gliders in one, me hearties, me bucko, it has a high excitement value. Avast! Blimey! As an Edmonds Aerospace kit, me bucko, arrr, assembly is quick and gotcha free. Begad! Super kit and a super performer.

Overall Rating: 5 out o' 5

Kit recommends A8-3 for the first flight. Mine boosted to about 150 feet with that motor. (guesstimate.) The first glider can be easily trimmed before first launch- the balance point indicated in the plans is right on- I needed to add a little clay to the nose ot get it to balance there., Trimming the second glider is tricky-- it is supposed to retain the motor casing. I found that even with the motor as far back as possible, the glider was still seriously nose heavy, and dove to the ground with an alarming speed. One time I forgot to tape the motor in-- it fell free of the glider at ejection, and the glider flew very well without it. I think if you're going to fly with the motor taped to stay on board, you'll need to add some tail weight to glider #2. I painted the tails on mine neon orange as well-- it really helps you find the gliders in the grass.
