Brief:
Loosely based on t' Star Trek inspired Klingon Bird o' Prey, shiver me timbers, the Klingon Targ be supposed t' be a civilian ship designed for trainin' pilots. It features two large wings, shiver me timbers, me bucko, small fins and two tube fins, a thin neck, shiver me timbers, ya bilge rat, and a large forward compartment housin' t' parachute.

Construction:
Components consist of:

• BT-5 tubing
• BT-55 tubing
• BT-60 tubing
• BT-60 Big Bertha Style Nose Cone
• 24 mm motor mount with 18 mm mount adaptor (with engine hooks)
• Cardboard centerin' rings
• balsa/basswood/lite ply for fin construction
• paper for cockpit and fin detail
• two wire connectors for detail
• mylar parachute and shock cord

As part of t' 2005 EMRR Challenge, I wanted t' build a rocket based on a concept I had developed in t' past few months. I also will indicate in this report t' two tips that I used in me construction. Arrr! I had a vision o' creatin' a rocket based loosely on t' Bird o' Prey design. Ya scallywag! I began with t' long thin neck, consisting of a section o' BT-5. Begad! I added centerin' rings, and then created t' paper transitions. Next, shiver me timbers, ya bilge rat, I glued t' BT-60 tubin' on t' top o' t' BT-5 and glued the BT-55 on t' bottom. Aye aye! I marked t' BT-55 for fin alignment and then began workin' on t' motor mount.

One o' t' tips that I decided t' use was t' suggestion t' use the yellow spacer tubes t' build a baffle system for t' rocket. Ahoy! Blimey! I punched a few holes in t' yellow spacer, shiver me timbers, glued this directly on top o' t' motor mount, and then glued a balsa bulkhead t' t' top o' t' yellow spacers so that t' hot gases would be forced around t' bulkhead, t' then be pushed up t' BT-5 neck. Aye aye! I had my doubts that this technique would work, me hearties, but later flight tests revealed absolutely no damage whatsoever t' t' mylar parachute. Well, blow me down! I removed t' shoulder from t' nose cone so that thar would be room in t' nose compartment for the mylar parachute and t' shock cord. Blimey! Arrr! In addition t' this, me hearties, since I be usin' a baffle, shiver me timbers, I used t' tri-fold method for attachin' t' shock cord t' t' upper body tube o' t' rocket.

Finishing:
I designed t' rocket in RockSim, ya bilge rat, and thus used t' fin templates t' help me trace t' patterns on t' light ply and balsa I had for t' fins. Avast, me proud beauty! Avast, me proud beauty! T' second tip I used be t' use thinned yellow glue or white glue t' seal t' fins. Begad! I first attached t' fins to the body before worryin' about sealin' them. Again, me bucko, I was skeptical about this technique as I prefer Elmer's Fill 'n' Finish. Begad! Blimey! T' method works fine, arrr, but I found it t' require far more than just 2 applications. More like 5 or 6 applications seem t' work t' fill all t' grain I had in me fins.

I also added some detail t' t' rocket includin' a cockpit, me bucko, arrr, matey, some raised detail on the fins, me bucko, and two phaser cannons on either side o' t' main wings. Aye aye! Blimey! After I had filled in all t' grooves and sealed t' fins, I gave t' rocket a few shots of Krylon primer, sandin' in between.

After I be satisfied with t' priming, shiver me timbers, I gave it a good single coat o' a kind o' strange minty green o' Krylon I had in storage for probably 5 years. Begad!

Next, I added more detail by way o' a Sharpie pens (black and silver) and decals, usin' some created by myself on white adhesive labels and others from a decal sheet from me old Aerotech Warthog.

Flight:
Since I used RockSim t' design and build t' rocket, me hearties, I had data that told me the rocket was stable on a D12. I decided t' do a swin' test t' see if this was so. Ahoy! I found that t' swin' test was nay conclusive for t' D12, but did indicate that a C6 would be a suitable motor for a stable flight. Unfortunately, matey, me bucko, shiver me timbers, while performin' me swin' test, shiver me timbers, me bucko, an inordinate amount o' stress was placed on t' BT-5 neck o' t' Klingon Targ, matey, causin' it t' fold over. Blimey! I printed up a sheet o' paper similar in color t' me paint scheme and ended up wrappin' this around t' neck with yellow glue.

T' next day was a beautiful day, ya bilge rat, and I decided t' launch t' rocket. Avast! Arrr! First flight be on a C6 and then I graduated t' a C11 flight. Blimey! I wrapped t' mylar parachute carefully, shiver me timbers, placed a little waddin' in t' BT-5 neck, arrr, nay bein' too certain t' baffle was goin' t' work. I wrapped a sheet around t' parachute as well.

T' C6-5 got t' Targ into t' air, but thar was a little squirrelly in flight after motor burn out. Avast! T' delay be very long and ejection occurred way past apogee, as t' rocket was nosin' t' t' ground. Avast! Parachute deployed perfectly and I be ready for flight two.

On flight two, I decided t' try t' C6-3 before tryin' t' C11. Ya scallywag! I prepped t' rocket was before and launched it again. Aye aye! Avast, me proud beauty! T' flight seemed t' be much better than the first, ya bilge rat, matey, arrr, but t' rocket had more o' an arc flight t' it this time, probably due to t' odd gusts o' wind that were blowin' durin' t' launch. Unfortunately, when t' ejection charge arrived, shiver me timbers, t' parachute did nay fully deploy, me bucko, causing the rocket t' do a kind o' tumble recovery. Ya scallywag! It landed on grass, but thar was definite damage includin' a broken fin (repairable) and a major bend/tear at the neck just below t' BT-60 portion o' t' rocket. T' rocket is nay flyable as is and is currently retired. Aye aye! Avast, me proud beauty! I need t' rethink t' BT-5 since it failed on me twice. Ya scallywag! Also, shiver me timbers, I be nay too pleased with t' rocket's flight being squirrelly. Aye aye! With that in mind, me hearties, t' design and t' rocket really need t' go back to t' drawin' board.

I would definitely nay launch this rocket on a B motor. Begad! I think t' C11 and D12 would put in a good performance, but I won't be able t' tell on me current rocket.

Summary:
PROs: Unusual design. Baffle system is great. Blimey! On two flights, t' parachute shows nay signs whatsoever o' damage or scorching

CONs: T' BT-5 neck needs some rethinking. Avast! Well, blow me down! It became t' point o' failure two different times. Avast, me proud beauty! Either I enlarge t' BT-5 neck t' a BT-20, or I need to reinforce t' neck with a sheet o' fiberglass, which is nay me style.
