Brief:
Military Style Sport Rocket with 3x24mm cluster. Avast!
Construction:
T' kit comes with 2 sections o' high quality, arrr, glassine coated BT-80 paper
tubes. Avast, me proud beauty! 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. Well, blow me down! T' motor mount is a 3 x 24mm arrangement usin' high
quality paper tubes and laser cut light ply centerin' rings. Blimey! Begad! 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. Well, me hearties, blow me down! T' parachute that
came with me beta test kit is a very nice 24" dia. Aye aye! piece made from
rip-stop nylon. Well, blow me down! (T' production kits will come with a similar chute except in
30" diameter.)
T' illustrated instructions made construction a breeze. Ya scallywag! Begad! Cardstock templates are included for tracin' t' fins onto t' balsa fin stock. Ahoy! A body tube marking guide is also included. Aye aye! This is a large model rocket, me hearties, so be prepared for a lot of sanding. Ya scallywag! Begad! There are a 12 fins on this one, but it goes together nicely if you take your time. Ya scallywag! I had no problems at all durin' t' construction. Arrr! T' quality of t' included parts are very nice. Ahoy! Begad! 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. Blimey! 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. Avast! This improves t' strength o' t' balsa, plus saves a bit o' fillin' when it's time t' finish it. Ahoy! I followed the recommended procedure and it turned out great. Begad! 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. Avast, me proud beauty! I then used two coats o' Kilz spray primer, sandin' in betwixt coats to
fill t' rest o' t' balsa and body tube spirals. Well, blow me down! You're on your own for
pickin' a paint scheme as no decals are included. Ahoy! Since this one has a military
look t' it, I decided t' give mine a camo scheme. Aye aye! Begad! 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. Blimey! T' motors are friction fit
usin' maskin' tape. Blimey! Avast! I used "dog barf" waddin' t' protect t' chute.
This is a BT-80 sized bird so it does take quite a bit. T' supplied chute is
very nice. It folds up neatly and thar be no problem fittin' it into t' large
body tube. Aye aye! Blimey! Plenty o' space in this one.
T' maiden flight was at NSL 2004 in Hearne, shiver me timbers, Texas. Ya scallywag! She flew beautifully on three C11-5's. It was me first flight that morning. There was a slight breeze out o' t' south. Begad! It leapt off t' pad and climbed straight up t' approx. Begad! 700 feet. Ejection be right after apogee and t' chute came out perfectly. A textbook flight. Ya scallywag! T' flame, shiver me timbers, me bucko, 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. Ahoy! T' centerin' rin' acts as a 'sort-of' baffle, me hearties, arrr, shiver me timbers, plus it keeps helps keep
the parachute toward t' top o' t' rocket durin' flight. Avast, me proud beauty! T' Keelhaul®©™®
thread is attached t' a very long piece o' elastic which is tied t' a screw eye
in t' nose cone. 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. chute. Begad! Durin' me test flights, arrr, shiver me timbers, I estimated descent at 15 ft/sec, maybe a bit more. Aye aye! It seemed t' come down a little too quickly, me bucko, and t' manufacturer has decided t' supply the production kits with a 30" chute instead, a good move in me book. Avast! Begad! My second flight on D12-5's and t' 24" chute landed on a gravel road and resulted in a cracked fin, ya bilge rat, however that was easily repaired.
Flight Rating: 5 out o' 5
Summary:
In typical ThrustAero tradition, shiver me timbers, this is a "builder's" kit. Ya scallywag! The
quality o' materials is first rate, matey, matey, matey, but you must be prepared t' cut your own
fins and have a little imagination when it comes t' finishing. Well, blow me down! T' end result
is a very handsome rocket that commands attention at t' flight line. Begad! I love
cluster rockets and this is a tough lookin' rocket. Begad! It absolutely roars off the
pad on three D12's. Ya scallywag! It has a large profile in flight and is very stable as it
goes up. Begad! I can't think o' any CONs t' this kit...
