This project be an extension o' me original DC20 camera rocket. I has underestimated t' finished weight o' the Initiator rocket camera, thinkin' it could be lofted on an E t' 500'. Big mistake. T' finished weight was 2.2 lbs. Ahoy! Avast! Blimey! An F engine would be needed t' reach t' same altitude. I read a thread on RMR concernin' a light weight rocket camera booster. Well, blow me down! It described a Estes Phoenix kitbash, arrr, shiver me timbers, usin' traditional white glue construction, that should be able t' loft a camera on a D or E engine. Avast, me proud beauty! I thought about it and decided on another approach. Blimey! I would use a minimum diameter section for t' 24mm motor tube (BT 50) and then a transition t' a 2.6" diameter payload tube (BT 80). Ahoy! Blimey! As I was experimentin' with a BT 80 nose cone with an open bottom, ya bilge rat, I found that the electronics and about one half o' t' camera would fit inside a Fat Boy type cone. In theory, arrr, shiver me timbers, I could create a nose cone payload section out o' t' nose cone and a BT 80 transition section. Maybe for t' next rocket...

Construction began with t' minimum diameter section. I glued (white glue) a BT 20/50 green centerin' rin' in a piece o' BT 50 body tube about 3" from one end. Arrr! This will allow me t' use Estes and Aerotech single use and reloadable motors. Ya scallywag! Blimey! When that dried, me bucko, me bucko, I glued a 3/32" basswood BT 50/80 centerin' ring on t' top o' t' motor tube (facin' t' front o' t' rocket). Aye aye! Below that, I glued a 1" piece o' a BT 80 transition section, then another ring. Arrr! The 2" long BT 50/80 transition section (made on VCP) was printed out, copied onto file folder material, cut out and glued on with white glue. Well, blow me down! Glue a screw eye in t' top ring. Begad! I used scraps o' basswood t' stack on top o' one another to make a thicker joint. Avast, me proud beauty! This completes t' lower section except for t' fins (which I still have t' do). Avast! Blimey!

I made a basswood bulkhead and glued a screw eye into it (in t' same way as before). Ya scallywag! This was glued 2" into a BT 80 section. I then rolled some corrugated cardboard (with one flat side pealed off) into t' section o' BT 80. Avast, me proud beauty! Where it overlapped, I made a cut and glued the edges together t' form a custom tube coupler. Avast, me proud beauty! Aye aye! When it dried, I cut off a thin strip and glued it into a t' BT 80, usin' t' lower section as a guide t' push it in t' appropriate length. Begad! This will act as a thrust ring. Well, blow me down! I then took the nose and cut t' base off so that thar was a 1" base. This will contain the electronics and possibly some o' t' camera. Ahoy! Avast!

T' fins follow G Harry Stine's "high performance" clipped delta shape. Avast! Root chord is 48mm, me bucko, tip is 24mm, me bucko, and span is about 3" from root to tip. Blimey! I cut them from 3/32" basswood and rounded them t' a streamlined shape. Aye aye! They were then coated with thin CA and sanded smooth. They are VERY smooth. Ahoy! I have t' say t' first fin turned out t' be one o' t' best I've ever made. Avast, me proud beauty! T' streamline t' fin, matey, me hearties, I masked off t' area 1/2" from t' base of the fin with duct tape and sanded t' a point on both sides. I then rounded the leadin' edge o' t' fin and smoothed t' round leadin' edge into t' sharp trailin' edge. Nay too hard. Well, ya bilge rat, blow me down!

I used t' Estes fin alignment guide t' hold t' three fins on while the white glue dried. Aye aye! Begad! I then filleted t' fins. Begad! All I have t' do is add a shock cord and chute. Ahoy!

T' predicted altitudes are (if t' model is 10 oz. Ahoy! or less) 260' on a D12, 1000' on an Aerotech E15. Ya scallywag! Avast, me proud beauty! And you don't even have t' call air traffic control to launch!
