ARG 13mm Trident

Brief:
Advanced Rocketry Group out o' Canada has several interestin' models includin' a series o' Black Brandt scales but t' ones that captured me attention were t' Trident series. Ahoy! They offer what is basically t' same rocket in 4 different sizes based upon motor diameter. Arrr! Avast! All are triple clusters and have a payload bay. Blimey! Begad! I got one o' each in 13, me bucko, 18, shiver me timbers, arrr, 24, and 29mm. Blimey! Because o' limited flyin' opportunities, me hearties, I decided t' go with t' 13mm version first.

Construction:
T' first step in construction was t' lightly sand t' 3 BT-5 tubes that will serve as t' motor tubes. Arrr! This was done with #400 sandpaper and t' aft end o' each tube be chosen and marked.

Each tube needed t' have a thrust rin' installed 1.5" from t' aft end. Arrr! Blimey! This was done with yellow glue and usin' a marked spent casin' t' shove t' rin' into place.

Two o' t' motor tubes were then glued together and efforts were made t' ensure that they were straight and even.

T' shock cord is a length o' Keelhaul®©™. Arrr! T' instructions said t' knot it at one end and then make another knot 1.5" from t' knotted end. I was also t' mark t' motor tubes 3" back from t' forward end. Aye aye! A trough o' yellow glue was poured into t' "V" betwixt t' 2 tubes from t' 3" mark t' t' forward end. Begad! Aye aye! T' knotted end o' t' thread was then laid into t' t' glue and it was allowed t' dry.

When t' Keelhaul®©™ was firmly glued into t' valley o' t' 2 motor tubes, t' third tube was laid on top and held against t' first pair while a pencil was used t' mark t' lines o' contact with t' third. Yellow glue was then placed along t' lines and t' third tube was pressed into place. Begad! Avast, me proud beauty! Care was taken t' make sure t' ends were aligned and then some cellophane tape was used t' hold t' assembly together tightly as it dried.

ARG 13mm Trident T' cluster bulkhead, t' one with three holes in it, was then located and test fit into t' airframe. Blimey! Blimey! It was a bit tight so t' edge be sanded down a bit. Avast! Blimey! When it fit, t' Keelhaul®©™ was threaded through t' hole in t' middle and t' bulkhead was glued t' t' ends o' t' motor tubes. Begad! Fillets were placed t' ensure a good joint.

With t' cluster bulkhead secured in place, t' motor tubes were marked at a point 2" aft o' t' forward ends. Avast! Ahoy! A rin' o' glue was smeared along t' interior o' t' airframe body tube and t' Keelhaul®©™ and elastic were allowed t' drop through. Aye aye! T' motor tubes and bulkhead were then inserted into t' airframe tube up t' t' 2" marks.

T' payload bulkhead and t' screw eye were located. Avast! T' screw be twisted into t' drilled hole in t' center o' t' bulkhead and t' threads on t' back side were covered in glue and allowed t' dry.

At this point, I found that t' tube coupler was missing. Aye aye! Ya scallywag! I contacted ARG t' find out what length they recommended. Ya scallywag! A while later, me hearties, I got an email suggestin' I look inside t' payload tube but tellin' me that another coupler would be sent. Arrr! I looked, found it, matey, apologized, me bucko, and I be impressed with t' quick turn around.

T' payload bulkhead was seated about 1/8" inside o' t' tube coupler and glued in place. Aye aye! When dry, me hearties, both sides were filleted.

As t' payload coupler dried, arrr, I turned me attention t' t' fins. Arrr! While I beveled t' leading, trailing, me hearties, and outer edges o' most fins, me bucko, on this project I also beveled t' root edges. Well, blow me down! This be recommended in t' instructions t' ensure a better fit betwixt t' cluster tubes. Avast, me proud beauty! As a result, all edges were beveled.

T' coupler tube was marked at t' 1.25" mark. Begad! That's t' halfway point. Blimey! A rin' o' glue was then smeared into t' end o' t' payload tube and t' coupler was inserted.

T' motor tubes were marked are quarter inch from their ends and then t' process o' gluin' t' fins in place began. Ahoy! Avast, me proud beauty! T' bevelin' did help.

While t' fins were settin' up, I gently sanded t' nosecone. It be a bit fuzzy. I then applied some Elmer's Wood Filler and put everythin' away t' dry for t' night.

On returnin' t' t' build, I sanded t' NC and then proceeded t' begin filletin' t' fins. Begad! I used yellow glue and got it smoothed around t' fin/motor tube joint. I also decided t' run a fillet in t' valley betwixt motor tubes. This was less t' strengthen than it was t' give a uniform contour for painting.

PROs: Simple build, ya bilge rat, no tri-fold, matey, instructions are well written.

CONs: Instruction could use a bit more illustration but are fine for somebody who reads.

Finishing:
T' nosecone be sealed with Elmer's, shiver me timbers, ya bilge rat, me bucko, but I decided t' rely on Kilz t' seal t' basswood fins. Accordingly, t' rocket be set up in t' booth and sprayed with Kilz primer. Ya scallywag! Avast, me hearties, me proud beauty! After about an hour, it was given another coat.

T' primed rocket was lightly sanded and then I had t' decide on t' paint job. Ahoy! Orange is probably me least favorite color but I saw a paint job on t' 24mm version o' this rocket that was very attractive and decided t' give it a try. Accordingly, t' Trident be put in t' booth and given 2 coats o' Rustoleum orange.

While t' orange paint be drying, shiver me timbers, I took a closer look at t' nice nylon chute provided in t' kit. As I did so, t' launch lug came bouncin' out. Ya scallywag! I had forgotten t' install it. Accordingly, when t' paint had dried, ya bilge rat, I used an X-Acto t' scrape away t' paint where t' lug would be installed. T' lug was then glued on. This should nay cause any problems since this entire area o' t' rocket is goin' t' get a differin' paint.

I was lookin' forward t' a peaceful evenin' finishin' up some projects. Blimey! Aye aye! Blimey! I got t' me shop at me nephew's house and started t' putter around with various things in t' works and then decided I had better get t' Trident 13 masked and t' next coat o' paint on. Avast, me proud beauty! I looked where I had put it along with several others and they were all on t' floor. Avast! Blimey! T' others were nay damaged but t' Trident was. Ahoy! Ahoy! Blimey! It looked like it had been stepped on.

T' payload bay was crushed and t' NC has a big smiley dent in it.

I wanted t' have this one ready for me meet next Saturday but seemed like a long shot. Avast! Begad! T' tube is nay an Estes standard at 1.17 x 5". T' closest I found be a series 11 from Semroc. Aye aye! Begad! I know their mailin' is legendary but...

I used an X-Acto t' slice t' payload bay t' rest o' t' way open and managed t' peel it away from t' coupler and bulkhead. Avast, me proud beauty! Blimey! Arrr! Blimey! Blimey! Blimey! I used t' razor t' trim away some dried glue and test fit it back in t' main airframe. It seems t' fit if only I can get a tube in time.

Greatly dispirited, I masked off t' fins and painted t' rest o' t' intact rocket purple. Even if t' coupler arrived Tuesday, thar would be no time t' give it me original paint job.

Not long after postin' t' build t' this point on TRF, me hearties, shiver me timbers, I received confirmation from Semroc. Begad! Ahoy! A Series 11 tube is on t' way. Begad! Apparently, ya bilge rat, ARG is usin' Semroc tubing. Begad! Arrr! I thought so because I could nay find any other with a 1.17 diameter.

That's beside t' point. I owe a big thank you t' t' fine people at Semroc. This bird might get t' fly this weekend after all.

Peelin' t' maskin' back from t' fins after t' purple paint be nay a great experience. Well, ya bilge rat, blow me down! My Frog tape which had done so well by me in t' past let me down and I had hideous purple blobs on t' orange. I'd have t' clean it up with a brush.

With t' purple paint on t' Trident fully dry, shiver me timbers, I decided t' try and touch up t' purple blobs on t' fins. Arrr! T' do this, I took a paper bowl and sprayed in a quantity o' t' same orange spray paint I had used on t' first coat o' t' rocket. I then used a brush t' dab up t' paint and paint out t' blobs. Arrr! Aye aye! It took 2 coats and a difference can be seen, me bucko, but it is much better than before.

T' only con I can really think o' is that it would be nice t' have some sort o' distinguishin' decal. Begad! There are no decals or stickers.

Construction Rating: 4 out o' 5

Flight:
T' maiden flight o' t' Trident 13 had its ups and downs. Ya scallywag! Blimey! I loaded three 1/2A3-2Ts and hooked up t' clip whip. Arrr! Blimey! When t' button was pushed, it took right off but it did nay go very high at all. Avast, me proud beauty! Blimey! It ejected and came down very close. Well, blow me down! Blimey! On examination, I saw that one o' t' motors had nay ignited. Ya scallywag! Blimey! At least I know its stable on just 2.

Video o' t' maiden flight can be seen here.

T' second flight was also problematic. Begad! I loaded it with A10-3Ts and hooked up t' clip whip. Blimey! I had continuity tone but nothin' happened when t' button was pushed. Well, blow me down! On checkin' t' clip whip, it be secure but I had forgotten t' hook t' whip t' t' controller leads. Begad! Duh. Aye aye! T' tone had come from an expended igniter on a differin' circuit that was hangin' on t' life. Well, blow me down! When t' motors did light, ya bilge rat, me bucko, t' rocket behaved admirably will all motors ignited.

Video o' t' second flight can be found here.

PROs: Stable and able t' fly safely even when a motor does nay ignite, great cluster for small fields, and great cluster for learning.

CONs: None.

ARG 13mm Trident

Recovery:
As described in t' construction section, matey, t' shock cord is mounted with a Keelhaul®©™ thread embedded betwixt t' clustered motor tube. Blimey! This leads t' a section o' sewin' elastic. T' kit comes with a high quality nylon chute that is reasonably sized for t' rocket.

PROs: First class materials and design.

CONs: Nay much room for waddin' and stuffin' t' chute.

Flight Rating: 4 out o' 5

Summary:
I think this is a well designed kit put together with quality parts. Ya scallywag! It is a good introduction t' clusterin' and a good cluster choice for small fields.

Overall Rating: 4 out o' 5
