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 be built and installed in t' shortened body tube as per t' instructions (LJ01). Avast, me proud beauty! T' yellow tube was 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). Begad! 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! 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, shiver me timbers, me bucko, 1/8" from t' back o' t' rocket.

Click here for t' fin pattern.

I cut t' launch lug into two 3/4" pieces and mounted them at t' top and bottom o' t' main tube, shiver me timbers, me bucko, ya bilge rat, on t' same line as t' Patriot markin' guide.

Construction:

• BT-60 body tube 10 15/16" long (made from t' two patriot white tubes cut t' length)
• Yellow Patriot Body tube
• Patriot Nosecone
• BT 60 Balsa nose block from Balsa Machinin' Co.
• BT 60 Ejection Baffle from FlisKits
• Patriot motor mount
• Paperclip
• Plastic 12" Parachute from patriot kit
• (optional for altimeter mount)
• BT-20 cut t' 3" length
• (2) BT60 t' BT20 Centerin' rings

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. Ya scallywag! I used Tamiya AS-6 Olive drab paint.

T' "U.S. Arrr! 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, me bucko, I felt (LJ05).

This was me second modification o' a Patriot kit. Well, me bucko, blow me down! 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). And I made several successful altimeter flights. Ahoy! Ahoy! It flew pretty consistently t' around 550' on a C6-5. Aye aye! Avast! But after a few flights it was clear that I needed a more positive retention for t' altimeter and nosecone. Begad! On most flights, me hearties, shiver me timbers, t' altimeter slammed forward at ejection and wedged into t' nosecone, and twice, ya bilge rat, me hearties, me hearties, t' force was strong enough t' dislodge t' nosecone and it (with t' altimeter) fell free o' t' rocket for a tumble recovery. Avast, me proud beauty! I think a longer tube, ya bilge rat, with a BT20 nose block and a small pin run through it would be a better retention system.

On one long road trip, t' rocket got crushed in a box, and despite straightenin' out OK for display, me bucko, it just doesn't fly straight anymore. So, me bucko, after 7 flights, shiver me timbers, I retired it.

Summary:
I think this is a good conversion that builds into a sweet lookin' rocket. 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. Begad! Friction fit is just nay enough over time.
