Brief:
T' Space Vehicle Gemini C is a military research rocket. Begad! I used this DC Gemini
rocket kit for me kit bash, arrr, because it has TTW fins, shiver me timbers, which means it is stronger
than t' other ones also you don't have t' worry about t' fin alignment.
Modifications:
Build t' motor mount per t' instructions and glue it in place. Avast, me proud beauty! Glue t' fins
in place. Avast! Blimey! Cut off a 50 mm long piece from one o' t' pods. Arrr! Well, me bucko, blow me down! Blimey! T' rest o' that pod
will make for t' body for t' shuttle. Arrr! Now cut t' other pod into 3 pieces
that are 50mm long. Avast! From t' Estes insert card, cut it so that you have a piece
that measures 35mm x 290mm long. Avast, me proud beauty! Glue t' 1/4 inch vent tube into one o' the
vent holes in t' central body tube. This serves as a post for t' shuttle to
hang onto. Avast, me proud beauty! Well, blow me down! Blimey! Plug t' other vent hole in t' body tube with glue. Avast, me proud beauty! Aye aye! Blimey! Glue t' insert
card onto t' tip o' t' fins so it covers 3 sides o' t' rocket, me hearties, ya bilge rat, and be sure
to leave t' side that has t' post clear. Begad! Blimey! Glue t' 4 short pieces cut from the
pods on t' fin tip o' each o' t' fins. Aye aye! Blimey! This will make t' outside motor. Begad! Blimey! Use
one o' 12" parachute and a shock cord. Avast! Glue t' shock cord onto the
standard 3-fold mount, me hearties, matey, then glue t' mount into t' body tube. Well, blow me down! Avast! Blimey! Lastly, attach
the parachute and nose cone t' t' shock cord.
For
the shuttle, glue t' 2 NC-20 nose cones into t' piece o' pod that make the
body for t' shuttle. Begad! Mark two lines 180 degrees apart on t' body.Usin' the
waste balsa from t' sheet o' fin stock, matey, shiver me timbers, make two wings and vertical
stabilizers for t' shuttle as shown in t' picture. Aye aye! Glue t' wings onto the
body o' t' shuttle and use t' vertical stabilizers so that they hold the
wings in a V shape. Well, blow me down! Well, matey, blow me down! Finally, shiver me timbers, glue t' vertical stabilizers on t' t' wings.
Construction:
T' components used in this rocket kit are:
Finishing:
I finished t' rocket with one coat o' Tamiya's gray primer and then I painted
the rocket in Tamiya intermediate blue (US NAVY, AS-19) and Tamiya haze gray
(TS-32) so it looks more like a military rocket. Avast, me proud beauty! I use t' supplied decals in
this kit.
Flight:
I got a chance t' fly it, arrr, because me nephew birthday. T' flights were held on
a somewhat cloudy day with winds at about 2 kph.
First flight was on a B4-4. Arrr! T' rocket moved slowly off t' pad for a nice stable and straight flight. Well, blow me down! Begad! Ejection happened at apogee and I recovered the rocket with no damage. Begad!
Second flight was on a C6-5. Aye aye! A fast launch! T' rocket went all but out of sight because o' t' low hangin' clouds. Aye aye! Ejection happened after apogee and I recovered t' rocket with no damage.
T' third flight was on B6-6. A stable and straight flight. Begad! Ejection happened way past apogee and I recovered t' rocket with damage t' body tube and t' shuttle snapped off on landing.
Recovery:
I put one parachute in, ya bilge rat, me bucko, because t' problem is that I don't really like 2
parachutes, I just want one, arrr, but I be worried about that if I only put one in,
the ejection gas won't deploy t' only parachute resultin' in a lawn dart.
Summary:
This rocket has good recovery and has through t' wall fin mounts so t' fins
are self-aligned, but two parachutes adds complications such as twisted shroud
lines. Avast, me proud beauty! I think t' Estes Gemini DC is a good rocket for this kit bash.
