Two PartsBrief:
The Geminee is a two-part boosted glider with laser-cut wings.

Construction:

Components: Two 3" body tubes, two balsa fuselages, four balsa wings (two per glider) each with two fins and elevators at each end. The motor goes in the rear of the glider. Since the two gliders break apart at ejection, there is no need for a shock cord. The balsa nose cone is glued into the front glider. Clay is included to balance the glider without the nose cone.

PRO: The laser-cut fins were very easy to separate and build with, because they were perfectly cut and fit together like a jigsaw puzzle at the base. There were a lot of illustrations, which made the directions easier to follow. A marking guide makes the tube marking easier.

Things to be careful about: Don't cut out the little diamonds marked on the wings -- these are for balancing the gliders. It was hard to get the wings, fins and elevators just right, but my dad helped.

Finishing:
It looks good without painting, so we didn't bother.

Construction Rating: 4 out of 5

Flight: Lift Off
We flew it three times, twice on a 1/2A3-2T, and once on an A3-4T. There's no parachute, so no wadding. The two gliders separate on ejection. The 1/2A flights were neat -- both gliders flew well after a straight (but quick) launch . You do have to pay attention to both gliders -- you need a friend (like my dad) to follow the other glider.

The one flight on the A3-4T was disastrous. It fell apart into five pieces (not just two like normal). The engine appeared to work ok, even with the normal ejection after 4 seconds. Maybe it's strong enough for the A engine.

DamageRecovery:
The glider recovery works great, at least with the 1/2A engine.

Flight Rating: 4 out of 5

Summary:
PROS: Cool flights, pretty easy to build. Gliders are fun. It's neat how it breaks into two gliders.

CONS: Might not be strong enough for an A engine, but that's just from one flight.

Overall Rating: 4 out of 5

That picture of the gliders in after the A3-4T flight looks just like mine. I agree that this kit, as it is, is not strong enough for a full A engine.

I made a 18 mm "middlescale" clone of the Giminee. I too had problems when it "re-kitted" itself on a B6-4 first flight. I have since glassed the wing root area with really lite(1/2 oz.) glass and had dozens of wonderful flights. The B4-2 and B4-4 are the motors for this bird. With the longer delay, the gliders separate in a 'downward bomb burst'and fly away in opposite directions, circling down for long gliding flights.

I wanted to spend a little time making the Geminee look great, so I sanded the wings into and airfoil shape, sealed and painted. End result looked good and the gliders flew well, but on launch it became obvious that the balance was off. On each of the two launches it arced severely (2nd time it lawn-darted with no damage). I might try to sand it more to get the balance just right, but in general would recommend just leaving the Geminee unpainted and unsanded.
