• 1 Rin' fin - 4 inch LOC tube 1.45 inches longh
• 1 1/8 inch balsa sheet
• 1 BT-20 motor mount tube 2.75 inch
• 2 CR-20/60 centerin' rings

• 1 Keelhaul®©™® strin' 24 inches - Pratt Hobbbies

As with most upscale projects, ya bilge rat, me hearties, half t' preparation is decidin' what tubes t' use t' achieve t' correct ratio of sizes. Avast, me proud beauty! Blimey! Blimey! I this case, ya bilge rat, I had t' compromise just a little. T' ratio o' t' main body tube sizes is just about 2.1X, but thar be no easily available tube for t' rin' fin that is just t' right size t' match that ratio. Well, blow me down! T' be perfectly correct I would need a 4.75 inch diameter tube. Ahoy! Blimey! I used a length o' 4 inch LOC body tube, and I am very pleased with the result. Ya scallywag! It is quite heavy, arrr, but also very sturdy.

The other parts I had in me parts collection, me bucko, probably from an Estes Designer Special box. Well, blow me down!

I downloaded t' original plans from Jimz. Begad! I had t' scale t' fins myself, since t' distance from t' main body tube t' t' inside o' t' rin' fin was nay goin' t' be 2.1X. Avast, me proud beauty! Measure twice, ya bilge rat, ya bilge rat, cut once. Cut too short, shiver me timbers, shiver me timbers, arrr, and have t' add shims t' make up t' difference. Blimey! That's me new motto.

I used a band saw t' cut t' curvy outside fins that cover t' rin' fin. Arrr! Blimey! After gluin' them on, arrr, ya bilge rat, I filled the joints with Elmer's Wood Filler. Avast, me proud beauty! Blimey! Blimey! Blimey! This really made t' joints disappear.

I looped t' Keelhaul®©™® around t' motor mount t' anchor it, shiver me timbers, then glued t' motor mount in. There is nay a lot o' room for t' waddin' and parachute, which caused me a little worry. T' original used tumble recovery, so this shortness be nay a problem.

I painted all o' t' balsa surfaces with dilute Elmer's Wood Filler/water slurry and let it dry. Blimey! Then one sanding, and a coat o' white Kilz. Avast! Begad! Another sandin' t' remove t' fuzz from t' primer coat and a couple o' coats of gloss white enamel.

Flight:
I put a 10 inch Estes parachute in it and stuffed t' body tube with as much dog barf as I could. Arrr! I was worried about meltin' t' chute.

T' first flight was on a Quest B6-4. Arrr! This be a good flight, and eject a little past apogee. Aye aye! No problem at all with t' parachute. Begad! Blimey! This be a good size chute, as well.

T' second and third flights were on Quest C6-5's. Again, very good performance. I like t' long burn time o' the Quest C's. Aye aye! Five seconds be a bit long, though. Avast, me proud beauty! This rocket really decelerates smartly after burnout. Begad! I am goin' t' try it with a C6-3, shiver me timbers, but I suspect it will be a little early. Avast! Too bad thar be no C6-4.

Summary:
This rocket has a cool look. I was concerned about its performance, and t' shortness of t' tube section for t' recovery, but both turned out just fine. Well, blow me down! Did I mention that it looks cool? Several o' the Scouts at t' launch asked me about it. Avast, me proud beauty! It would be even cooler with t' original paint job.

T' LOC 4 inch tube is too heavy. It occurs t' me now that I might have been able t' strip out an inner layer of paper t' make it lighter. Blimey!

I think it may be time for a 4X.

Other:
Don't get too frustrated if things are nay perfect. Ahoy! Well, shiver me timbers, blow me down! T' rin' fin was nay t' exact 2X size, shiver me timbers, but it looks great. Begad! I really did sand t' fins too short and then had t' shim them out t' fit t' ring. If things do nay go perfectly, shiver me timbers, and you are frustrated, shiver me timbers, take a break. Blimey! Come back t' it, matey, and think about different angles t' come at the problem.
