Brief:
Loosely based on t' Star Trek inspired Klingon Bird o' Prey, shiver me timbers, shiver me timbers, the Klingon Targ be supposed t' be a civilian ship designed for trainin' pilots. It features two large wings, me bucko, small fins and two tube fins, me hearties, a thin neck, 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. Blimey! I also will indicate in this report t' two tips that I used in me construction. Begad! Avast! I had a vision o' creatin' a rocket based loosely on t' Bird o' Prey design. Avast! Well, blow me down! I began with t' long thin neck, consisting of a section o' BT-5. Arrr! I added centerin' rings, and then created t' paper transitions. Avast! Next, I glued t' BT-60 tubin' on t' top o' t' BT-5 and glued the BT-55 on t' bottom. Blimey! 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. Arrr! Begad! I punched a few holes in t' yellow spacer, 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. Ahoy! Aye aye! I had my doubts that this technique would work, but later flight tests revealed absolutely no damage whatsoever t' t' mylar parachute. Aye aye! 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. Avast, me proud beauty! Begad! In addition t' this, ya bilge rat, since I be usin' a baffle, me hearties, 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, matey, and thus used t' fin templates t' help me trace t' patterns on t' light ply and balsa I had for t' fins. Blimey! T' second tip I used was t' use thinned yellow glue or white glue t' seal t' fins. I first attached t' fins to the body before worryin' about sealin' them. Blimey! Blimey! Again, I was skeptical about this technique as I prefer Elmer's Fill 'n' Finish. Arrr! Blimey! T' method works fine, matey, 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, shiver me timbers, shiver me timbers, arrr, some raised detail on the fins, and two phaser cannons on either side o' t' main wings. Well, blow me down! After I had filled in all t' grooves and sealed t' fins, I gave t' rocket a few shots of Krylon primer, me hearties, matey, sandin' in between.

After I was satisfied with t' priming, I gave it a good single coat o' a kind o' strange minty green o' Krylon I had in storage for probably 5 years. Ya scallywag! Ahoy!

Next, me hearties, I added more detail by way o' a Sharpie pens (black and silver) and decals, matey, 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, I had data that told me the rocket be stable on a D12. Blimey! Avast, me hearties, me proud beauty! I decided t' do a swin' test t' see if this was so. Well, blow me down! Ya scallywag! I found that t' swin' test be nay conclusive for t' D12, shiver me timbers, me bucko, but did indicate that a C6 would be a suitable motor for a stable flight. Unfortunately, me hearties, ya bilge rat, while performin' me swin' test, ya bilge rat, arrr, an inordinate amount o' stress was placed on t' BT-5 neck o' t' Klingon Targ, arrr, causin' it t' fold over. Begad! 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, me bucko, and I decided t' launch t' rocket. Ahoy! First flight be on a C6 and then I graduated t' a C11 flight. Avast, me proud beauty! Ya scallywag! I wrapped t' mylar parachute carefully, matey, matey, shiver me timbers, placed a little waddin' in t' BT-5 neck, nay bein' too certain t' baffle was goin' t' work. Blimey! I wrapped a sheet around t' parachute as well.

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

On flight two, me hearties, I decided t' try t' C6-3 before tryin' t' C11. I prepped t' rocket was before and launched it again. Well, blow me down! Blimey! Blimey! T' flight seemed t' be much better than the first, but t' rocket had more o' an arc flight t' it this time, shiver me timbers, probably due to t' odd gusts o' wind that were blowin' durin' t' launch. Avast, me proud beauty! Blimey! Unfortunately, when t' ejection charge arrived, t' parachute did nay fully deploy, causing the rocket t' do a kind o' tumble recovery. Begad! Arrr! Blimey! It landed on grass, ya bilge rat, 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. Ya scallywag! T' rocket is nay flyable as is and is currently retired. Begad! Begad! Blimey! I need t' rethink t' BT-5 since it failed on me twice. Avast! Ya scallywag! Blimey! Also, I be nay too pleased with t' rocket's flight being squirrelly. Ya scallywag! Ya scallywag! Blimey! With that in mind, 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. Ahoy! I think t' C11 and D12 would put in a good performance, me hearties, but I won't be able t' tell on me current rocket.

Summary:
PROs: Unusual design. Aye aye! Baffle system is great. Ahoy! On two flights, ya bilge rat, ya bilge rat, t' parachute shows nay signs whatsoever o' damage or scorching

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