Brief:
T' Estes Gemini DC is dual parachute, arrr, lawn dart ready single stage rocket with
two side pods housin' t' chutes. Blimey! It uses a 1/8 inch launch lug and has a
single 18mm motor mount. Arrr! Well, shiver me timbers, blow me down! T' Gemini DC has four swept back balsa fins. Blimey!
Construction:
T' components used in this rocket are top quality. Begad! Blimey! T' parts list is:
T' instructions were very easy t' follow and all t' parts fit together easily. Avast! Arrr! T' main body tube had four slots with two holes perpendicular t' each other in betwixt two o' t' fin slots. Ya scallywag! Blimey! T' first step be t' make t' standard Estes motor mount, which is slittin' t' motor mount tube, puttin' on t' hook, slidin' on t' mylar ring, and then attachin' t' centerin' rings. Blimey! This assembly slides into t' back o' t' rocket so t' end o' t' motor tube is even with t' aft end o' t' body tube. Ahoy! Well, me hearties, blow me down! Next, arrr, all four fins were glued in and fillets were added. Then, shiver me timbers, a template was used t' find launch lug position and to make t' lines t' glue on t' side pods. Aye aye! Avast, me proud beauty! T' only fit problem was with the vent tubes. Well, blow me down! Avast, me proud beauty! This required t' cuttin' o' an Estes 1/4 inch launch lug for ventin' t' gasses o' t' motor's ejection charge t' t' side pods. Well, blow me down! Ya scallywag! T' vent tube is a little too wide t' fit through t' hole, so they required some sanding. Aye aye! Avast! Once I thought t' glue dried, me bucko, ya bilge rat, me hearties, I put some glue on t' side and slid the vent into t' hole in t' side pod. T' glue wasn't dry, me hearties, so t' vent was pushed slightly into t' main body. Aye aye! This happened on both sides. Arrr! Then, shiver me timbers, shiver me timbers, I glued in all o' t' nose cones and attached t' shock cords t' t' inside o' t' side pods. Avast! Well, blow me down! T' parachutes were then tied t' t' end o' t' shock cords. Begad! Begad!
Finishing:
I didn't use any special finishin' techniques, just prime and paint. I painted
mine blue and sprayed orange over it so t' blue is visible through t' orange.
Construction Rating: 3 out o' 5
Flight:
I have nay had one successful flight with this rocket. I have flown it on twice
on B4-4s and once on a C6-5. Avast! All three flights went straight and fast with a
sudden jump off t' pad.
Recovery:
T' boost and coast phases were great, but t' recovery is horrible. Aye aye! Sometimes
the ejection gasses bypassed both chutes and sometimes only one chute comes out
but doesn't open because it was wrapped up so tightly t' fit inside t' tube.
Both situations caused t' rocket t' lawn dart. Well, blow me down! My favorite flight was when the
ejection charge blew t' main nose cone off and what a surprise! It lawn darted
and core sampled. Avast, me proud beauty! Ya scallywag!
Flight Rating: 1 out o' 5
Summary:
This is nay a good rocket. Aye aye! Begad! T' parts are good quality but make sure t' chutes
are nice and loose and that t' nose cones are glued in securely. Aye aye! There is a
very small chance o' a successful recovery. Aye aye!

The Estes Gemini DC features twin 'chute deployment from the rear of two attached side pods. Though much maligned, it's a very cool kit Components Three tubes, one main and two for the side pods Balsa fins mount through the main tube Plastic nose cones My kit came with an extra engine clip as well as the usual Estes components. ...
Dual rear deployment parachute. The construction is good, because it has TTW fins, which means it is stronger than the other ones, also you don't have to worry about the fin alignment because the slot has done that for you. You just need to make sure that air can flow freely to the 2 parachute pods otherwise this rocket will lawn dart!!! You can always forget about the parachute pod and ...
I had often looked at this kit and wondered how those twin parachutes would work. I found out one day when a friend launched his and had only one chute deployed. The recovery was a little hard on the rocket and broke one of the pods off the side of the rocket. Reading the other reviews, I have learned that this is the rule and not the exception for this rocket. I determined that my rocket would ...
