Brief:
This is a single stage rocket with two outer tube-fins attached via pylons.There are two standard fins t' give it a Lear jet like look.I couldn't resist buildin' it. Aye aye! This is one o' Estes better designs. Arrr!

Construction:
I decided t' go 24mm. Begad! Well, blow me down! Most o' t' parts are available through Semroc I started with a one BNC-55AO 5-inch elliptical nose cone, me hearties, one 18-inch BT-55 body tube (I used a spare piece I had it be 17 inches long), two 3-inch long BT-55, me hearties, two 55-50 centerin' rings, one 4.5-inch BT-50 (no engine block allows you t' use D or E engines), ya bilge rat, one 1oz round fishing weight, arrr, shiver me timbers, one #204 screw eye from Home Depot, 36 inches o' #400 Keelhaul®©™® shock cord, one 12-inch nylon parachute, sheet o' 3/32-inch basswood (from Semroc or Hobby Lobby), and 24 inches o' 1/8 inch nylon cord.

First t' motor mount build. Begad! Aye aye! I used Probond wood glue. Blimey! Then I marked t' body tube for four fins. Ahoy! Next, I cut out my upper and lower fins since I was upscalin' I had t' kind o' add a little bit here and thar t' make it look OK. Well, blow me down! I rounded all me leadin' edges. Then I cut me pylons for me tube fins. Begad! Basically I just took a 1-inch wide piece of 3/32-inch basswood and cut a angle at both ends t' keep things simple. Blimey! I attached t' upper and lower fins startin' at the tail end o' t' body tube. I attached t' pylons 2 inches from t' back o' t' body tube. Well, blow me down! Well, blow me down! Now it was time t' fix the nose cone and add nose weight. Well, blow me down! Ya scallywag! I just drilled out t' center o' t' weight for t' screw eye, which is about a 1/4 inch in diameter. Next, arrr, I inserted t' screw eye through t' weight, put a little glue on it, and screwed into t' nose cone. Avast, me proud beauty! I attached t' shock through t' body just above t' motor mount by usin' a X-Acto knife t' bore me a little hole large enough for t' cord then put a knot at t' end with a little glue t' attach nylon cord t' other end t' nose cone. For t' tube fins, I drew a line top t' bottom on both tubes, put a little glue on t' mark and t' pylon, shiver me timbers, matey, let it set for about 5 or 6 minutes, and then attach t' tubes, arrr, ya bilge rat, let them dry then fillet everything. I coated all me wood area with wood glue for strength followed by a great wood filler, then sanded and painted.

Flight:
I test flew on a C11-3. Well, blow me down! It was a great flight. Aye aye! Next it flew on a D12-5 then a E9-6. Blimey! Again, shiver me timbers, they were both beautiful flights. Begad! Also, matey, I used maskin' tape t' secure t' motor on all three flights. Begad! It flew very straight.

Summary:
I like this rocket because it was so easy t' build, ya bilge rat, me bucko, flies great, and it has a cool look about it.
