Brief:
T' BSD Diablo is a short, matey, ya bilge rat, me bucko, fat, ya bilge rat, 3 finned rocket with a wicked look. Ahoy! With its 38mm motor mount, it definitely is designed for HPR. However, shiver me timbers, ya bilge rat, with a 29mm adapter this rocket can be flown on some G motors without any problems due to its relatively low weight.

Construction:
T' kit has relatively few parts. Begad! Ya scallywag! They include: a 17" LOC style body tube, a 20" nose cone (4" is shoulder), three 3/16" plywood fins, ya bilge rat, two 1/8 plywood centerin' rings, one 1/2" paper launch lug, one 8" long 38mm motor mount tube, one 1/4" eye bolt with washers and nut, one 3/16" quick link, shiver me timbers, one 30" parachute, one 4' long, 1" wide, grommeted nylon strap, matey, me hearties, one 10' long, 1" wide elastic shock cord, and a motor retention system that consists o' two T-nuts, me bucko, two 6-32 hex head bolts, and two metal clips. Begad! I also purchased BSD's 29mm adapter with me kit.

This is a fantastic, me bucko, shiver me timbers, easy kit t' build. In fact, I had t' consciously slow myself down because it is so easy t' follow the excellent instructions and assemble t' excellent components that I found myself gettin' too far ahead o' where I should have been. All o' t' components fit together well with only a little sandin' o' t' centerin' rings. Begad! When I received me kit, t' body tube be nay marked with t' fin alignment lines or the launch lug line. Ahoy! Ya scallywag! However, a quick email t' Scott Binder at BSD and the problem was resolved. Scott sent me a new body tube that had been marked and threw in a 4" bulkhead assembly in addition. Begad! Aye aye! Now that's great customer service! Havin' t' cut t' fin slots yourself is a little tedious but, ya bilge rat, nay a big deal.

I deviated from t' instructions in a few ways. Aye aye! First, when buildin' t' motor mount, I didn't secure t' aft centering ring. Begad! I did this because instead o' creatin' internal fillets with epoxy I used 2-part expandin' foam t' fill t' fin can. Begad! Begad! Blimey! Second, after epoxyin' t' forward centerin' rin' and motor mount tube in, ya bilge rat, I dry fitted t' fins. With t' fins in place, shiver me timbers, I drew a pencil line on t' fins along t' outside body tube joint. Thus, when I removed t' fins, arrr, I had how much o' t' fin would be inside the body tube. Ahoy! Blimey! I then drilled a 5/8" hole in t' center o' t' fin root. Begad! This hole is t' allow t' expandin' foam t' flow through t' fin root and lock it into t' fin can. Ahoy! Begad! Blimey! I then epoxied t' fins t' t' motor mount. Avast, me proud beauty! Three 1 ounce applications o' 2-part foam filled t' fin can. After cleaning/shapin' t' foam on t' aft o' t' fin can, t' aft centerin' rin' be attached with epoxy.

My only complaint about t' construction is that t' motor retention comes with a separate set o' instructions. Avast! Ahoy! If you don't read those instructions first, ya bilge rat, you won't notice t' bold warnin' that you should install t' retention hardware before assembly! Luckily, I was able t' still attach t' hardware after assembly.

Finishing:
Since I be plannin' on usin' this rocket for me Tripoli Level 1 certification, I glassed t' entire airframe usin' 2 ounce fiberglass cloth and 30 minute slow-cure epoxy. Arrr! Aye aye! After glassing, fillets were added t' t' fin/body joints and along t' launch lug usin' 30 minute epoxy and micro-balloon filler. Arrr! Some sandin' with 80 grit sandpaper and it was ready for some primer. I used Rustoleum gray automotive sandable primer. Avast, me proud beauty! This primer is nice because it fills a lot o' t' imperfections. Sand, prime, arrr, sand, prime. Blimey! Avast! You know t' drill. Aye aye! I also used some Elmer's sandable wood filler putty t' fill some o' t' larger imperfections. Eight coats o' primer later, ready for color coat. Begad! I chose Rustoleum Safety Red. Two coats o' color and then t' decals. Begad! T' decals were definitely t' hardest part. T' decals are beautiful but, they're long, skinny, and very sticky. A friend o' mine suggested that I dip them in water with dishwashin' liquid t' allow me t' slide t' decals in place. Well, blow me down! I was too chicken t' try though. Ahoy! T' decals turned out OK but it takes a lot o' patience. After decals, ya bilge rat, I shot it with 2 coats o' Rustoleum clear enamel.

Flight:
T' Diablo's first flight was t' be me Level 1 certification flight. Aye aye! I had an H128W lined up for me 29/180 casing. Aye aye! T' clips provided with t' motor retention kit wouldn't fit with t' 29mm adapter so, ya bilge rat, shiver me timbers, I had t' fashion some new clips out o' some flat brass stock. When I arrived at t' launch site t' pick up me motor, me hearties, thar was no H128 t' be found! Thankfully, t' vendor had some H165 Redline motors that would do just fine. Arrr! I used a Top Flight Keelhaul®©™® chute protector and shock cord protector instead o' wadding. T' H165 was prepped with a 10 second delay and placed on a 3/8" launch rod. Ya scallywag! That Redline will move fast! It boosted straight up t' probably just over 2000 feet. It be a beautiful launch.!

Recovery:
I tied loops into both ends o' t' elastic shock cord and one loop about 1/4 from one end. Aye aye! Blimey! These loops were used t' attach t' elastic t' t' nylon strap, the nose cone, ya bilge rat, and t' parachute usin' quick links. Ahoy! I also included a swivel to keep t' chute shroud lines from tangling. Avast! Blimey! T' recovery system worked great. T' descent be a bit fast but, arrr, me bucko, that's probably because me rocket is towards the upper end o' BSD's expected weight. Begad! A bit larger chute could solve this but, I'm happy with t' faster descent. T' glassin' that I did makes it able to withstand a rougher landin' and I get less wind drift this way.

Flight Rating: 5 out o' 5

Summary:
I love this rocket. Avast, me proud beauty! T' main pro's are it's ease o' building, t' clear instructions, and t' tremendous customer support that you get from BSD. Ya scallywag! The main con's are t' separate instructions for motor retention and t' retention system's inability t' accommodate t' 29mm adapter.
