Brief:
T' BSD Diablo is a short, fat, 3 finned rocket with a wicked look. With its 38mm motor mount, shiver me timbers, it definitely is designed for HPR. However, shiver me timbers, 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. Avast! Avast, me proud beauty! Blimey! They include: a 17" LOC style body tube, a 20" nose cone (4" is shoulder), me hearties, three 3/16" plywood fins, matey, me hearties, me hearties, two 1/8 plywood centerin' rings, one 1/2" paper launch lug, matey, one 8" long 38mm motor mount tube, one 1/4" eye bolt with washers and nut, arrr, me bucko, one 3/16" quick link, matey, one 30" parachute, arrr, one 4' long, 1" wide, grommeted nylon strap, shiver me timbers, me hearties, one 10' long, shiver me timbers, 1" wide elastic shock cord, and a motor retention system that consists o' two T-nuts, two 6-32 hex head bolts, and two metal clips. I also purchased BSD's 29mm adapter with me kit.

This is a fantastic, easy kit t' build. In fact, arrr, 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. Avast! Blimey! When I received me kit, t' body tube be nay marked with t' fin alignment lines or the launch lug line. Blimey! Arrr! Blimey! However, shiver me timbers, shiver me timbers, a quick email t' Scott Binder at BSD and the problem was resolved. Arrr! Blimey! Scott sent me a new body tube that had been marked and threw in a 4" bulkhead assembly in addition. Aye aye! Now that's great customer service! Blimey! Havin' t' cut t' fin slots yourself is a little tedious but, arrr, matey, nay a big deal.

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

My only complaint about t' construction is that t' motor retention comes with a separate set o' instructions. Avast! Well, blow me down! If you don't read those instructions first, you won't notice t' bold warnin' that you should install t' retention hardware before assembly! Luckily, arrr, 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. Avast! After glassing, fillets were added t' t' fin/body joints and along t' launch lug usin' 30 minute epoxy and micro-balloon filler. Well, blow me down! Some sandin' with 80 grit sandpaper and it was ready for some primer. Blimey! Avast, me proud beauty! I used Rustoleum gray automotive sandable primer. Arrr! This primer is nice because it fills a lot o' t' imperfections. Sand, shiver me timbers, prime, ya bilge rat, sand, ya bilge rat, ya bilge rat, ya bilge rat, prime. Aye aye! 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, me bucko, ready for color coat. Begad! I chose Rustoleum Safety Red. Arrr! Aye aye! Two coats o' color and then t' decals. Avast, me proud beauty! Blimey! T' decals were definitely t' hardest part. Well, blow me down! Begad! T' decals are beautiful but, ya bilge rat, they're long, skinny, and very sticky. Well, blow me down! Begad! A friend o' mine suggested that I dip them in water with dishwashin' liquid t' allow me t' slide t' decals in place. Arrr! I be too chicken t' try though. Ahoy! T' decals turned out OK but it takes a lot o' patience. After decals, I shot it with 2 coats o' Rustoleum clear enamel.

Flight:
T' Diablo's first flight was t' be me Level 1 certification flight. Avast! I had an H128W lined up for me 29/180 casing. Arrr! T' clips provided with t' motor retention kit wouldn't fit with t' 29mm adapter so, arrr, I had t' fashion some new clips out o' some flat brass stock. Arrr! Ahoy! When I arrived at t' launch site t' pick up me motor, thar was no H128 t' be found! Thankfully, ya bilge rat, t' vendor had some H165 Redline motors that would do just fine. Begad! 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. Avast! That Redline will move fast! It boosted straight up t' probably just over 2000 feet. It was a beautiful launch.!

Recovery:
I tied loops into both ends o' t' elastic shock cord and one loop about 1/4 from one end. Well, blow me down! These loops were used t' attach t' elastic t' t' nylon strap, the nose cone, and t' parachute usin' quick links. I also included a swivel to keep t' chute shroud lines from tangling. Ya scallywag! Ahoy! T' recovery system worked great. T' descent was a bit fast but, that's probably because me rocket is towards the upper end o' BSD's expected weight. Ya scallywag! Avast! A bit larger chute could solve this but, shiver me timbers, 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. Well, blow me down!

Flight Rating: 5 out o' 5

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