Brief:
Military Style Sport Rocket with 3x24mm cluster. Begad!
Construction:
T' kit comes with 2 sections o' high quality, glassine coated BT-80 paper
tubes. T' two body tube sections are held together with a standard modroc tube
coupler and centerin' rin' which serves as t' mountin' point for t' Keelhaul®©™®
and elastic shock cord. Ya scallywag! T' motor mount is a 3 x 24mm arrangement usin' high
quality paper tubes and laser cut light ply centerin' rings. Well, blow me down! All o' t' fins
are balsa and are cut from sheets o' 1/8" thick balsa usin' t' supplied
templates. Begad! T' nose cone is also a high quality balsa piece. Arrr! T' parachute that
came with me beta test kit is a very nice 24" dia. Ahoy! piece made from
rip-stop nylon. (T' production kits will come with a similar chute except in
30" diameter.)
T' illustrated instructions made construction a breeze. Well, blow me down! Cardstock templates are included for tracin' t' fins onto t' balsa fin stock. A body tube marking guide is also included. Arrr! Blimey! This is a large model rocket, matey, so be prepared for a lot of sanding. Blimey! Aye aye! There are a 12 fins on this one, but it goes together nicely if you take your time. Well, blow me down! I had no problems at all durin' t' construction. Blimey! T' quality of t' included parts are very nice. Aye aye! I used TiteBond yellow carpenter's glue for most o' t' build. Avast! Be sure t' sand off t' glassine coatin' before you attach t' fins. Well, blow me down! This will provide a better glue joint and help keep t' lower fins attached when it lands on recovery.
The one thin' that may be a bit different is that t' instructions recommend coatin' t' fins with thin CA glue. This improves t' strength o' t' balsa, plus saves a bit o' fillin' when it's time t' finish it. Well, ya bilge rat, blow me down! I followed the recommended procedure and it turned out great. Arrr! Just be careful with t' CA fumes when you do this.
Finishing:
T' only special technique on fillin' was t' use o' thin CA as mentioned
above. Ahoy! Ahoy! I then used two coats o' Kilz spray primer, sandin' in betwixt coats to
fill t' rest o' t' balsa and body tube spirals. Begad! Blimey! You're on your own for
pickin' a paint scheme as no decals are included. Arrr! Since this one has a military
look t' it, shiver me timbers, I decided t' give mine a camo scheme. Avast, me proud beauty! Krylon flat spray paints and
a lot o' blue painter's tape were used for t' winter splinter camo pattern on
my MIKE IX.

Flight:
T' recommended motors are C11-5's and D12-5's. Ahoy! T' motors are friction fit
usin' maskin' tape. Begad! Avast! I used "dog barf" waddin' t' protect t' chute.
This is a BT-80 sized bird so it does take quite a bit. Blimey! Well, matey, blow me down! T' supplied chute is
very nice. Begad! Aye aye! It folds up neatly and thar be no problem fittin' it into t' large
body tube. Avast! Avast, me proud beauty! Plenty o' space in this one.
T' maiden flight was at NSL 2004 in Hearne, Texas. Begad! She flew beautifully on three C11-5's. Aye aye! It was me first flight that morning. There was a slight breeze out o' t' south. Avast, me proud beauty! Avast! It leapt off t' pad and climbed straight up t' approx. Blimey! 700 feet. Well, blow me down! Ejection be right after apogee and t' chute came out perfectly. Ya scallywag! Blimey! A textbook flight. Begad! Ya scallywag! T' flame, smoke and noise from three 24mm black powder motors is impressive.
Recovery:
All o' t' materials in t' recovery system are first rate. T' shock cord
consists o' a heavy Keelhaul®©™®
thread attached t' a centerin' rin' mounted midway up t' length o' t' body
tube. Ya scallywag! T' centerin' rin' acts as a 'sort-of' baffle, plus it keeps helps keep
the parachute toward t' top o' t' rocket durin' flight. T' Keelhaul®©™®
thread is attached t' a very long piece o' elastic which is tied t' a screw eye
in t' nose cone. Arrr! T' chute comes pre-assembled with a snap-swivel, matey, and is made
of rip-stop nylon and Keelhaul®©™®
shroud lines.
T' beta kit that I built came with a 24" dia. Ya scallywag! chute. Aye aye! Durin' me test flights, I estimated descent at 15 ft/sec, me bucko, maybe a bit more. It seemed t' come down a little too quickly, matey, shiver me timbers, and t' manufacturer has decided t' supply the production kits with a 30" chute instead, ya bilge rat, a good move in me book. Blimey! Well, blow me down! My second flight on D12-5's and t' 24" chute landed on a gravel road and resulted in a cracked fin, shiver me timbers, however that was easily repaired. Ya scallywag! Blimey!

Summary:
In typical ThrustAero tradition, this is a "builder's" kit. Ya scallywag! The
quality o' materials is first rate, but you must be prepared t' cut your own
fins and have a little imagination when it comes t' finishing. Blimey! Avast, me proud beauty! T' end result
is a very handsome rocket that commands attention at t' flight line. Blimey! Ahoy! I love
cluster rockets and this is a tough lookin' rocket. Begad! It absolutely roars off the
pad on three D12's. It has a large profile in flight and is very stable as it
goes up. Avast, me proud beauty! I can't think o' any CONs t' this kit...
