Brief:
This is a modification o' t' Estes Patriot kit into a semi-scale model o' t' Little John tactical nuclear missile
T' motor mount was built and installed in t' shortened body tube as per t' instructions (LJ01). Aye aye! T' yellow tube be modified into a payload section by use o' a balsa nose block from Balsa machining. I formed a "eye hook" from a paperclip and ran it through t' balsa block and bent t' ends over inside t' payload bay so that it couldn't come out(LJ02). Ahoy! Ahoy! I used a spare BT20 tube cut t' 3" long and two BT60 t' BT 20 centerin' rings t' make a holder for a PerfectFlite ALK15 Altimeter.
I cut a hole in t' base o' t' nosecone t' allow t' altimeter t' fit and held it in with a foam plug(LJ03). Arrr! Begad! T' FlisKits baffle served as t' shock cord mount (LJ04)
T' fins were made from 1/16" balsa and mounted on t' same lines as t' patriot fins, arrr, 1/8" from t' back o' t' rocket.

I cut t' launch lug into two 3/4" pieces and mounted them at t' top and bottom o' t' main tube, me bucko, me bucko, on t' same line as t' Patriot markin' guide.
Construction:
Aside from t' addition o' a payload bay, t' rocket goes together very much like t' patriot kit.
Paintin' is relatively simple since t' entire rocket is olive drab. Avast! I used Tamiya AS-6 Olive drab paint.
T' "U.S. Well, blow me down! Army" letters are vinyl 1/4" R/C aircraft letterin' that I laid out on wax paper and then cut slivers out o' t' simulate t' look o' army stencils.
I then laid maskin' tape over t' letters and peeled them off o' t' wax paper and transferred them t' t' rocket.
T' finished rocket turned out t' look a lot like t' real thing, I felt (LJ05).
This was me second modification o' a Patriot kit. Begad! T' first was a two-stage kit bash I built for t' 2009 EMRR challenge called t' "Yellow Jacket" (LJ07)
Flight:
T' rocket flew very well (LJ06). Ahoy! Blimey! Arrr! Blimey! And I made several successful altimeter flights. Arrr! Blimey! Avast, ya bilge rat, me proud beauty! Blimey! It flew pretty consistently t' around 550' on a C6-5. Aye aye! Blimey! Arrr! Blimey! But after a few flights it be clear that I needed a more positive retention for t' altimeter and nosecone. Blimey! Blimey! On most flights, t' altimeter slammed forward at ejection and wedged into t' nosecone, me hearties, and twice, me bucko, t' force was strong enough t' dislodge t' nosecone and it (with t' altimeter) fell free o' t' rocket for a tumble recovery. I think a longer tube, me hearties, with a BT20 nose block and a small pin run through it would be a better retention system.
On one long road trip, arrr, me bucko, t' rocket got crushed in a box, arrr, and despite straightenin' out OK for display, arrr, shiver me timbers, it just doesn't fly straight anymore. Blimey! So, ya bilge rat, me bucko, after 7 flights, matey, I retired it.
Summary:
I think this is a good conversion that builds into a sweet lookin' rocket. Arrr! It needs a more positive nosecone and altimeter retention method though.
Other:
This kit taught me a lot about t' importance o' really securin' things like altimeters and nose cones. Avast! Blimey! Friction fit is just nay enough over time.
