Brief:
2X upscale o' t' original Estes Astron Sprite.

Construction:

• 1 Big Bertha nose cone
• 1 BT-60 body tube 5 7/8 inches
• 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 18mm thrust ring
• 1 Motor hook
• 1 1/8 inch launch lug 2 inches
• 1 Keelhaul®©™® strin' 24 inches - Pratt Hobbbies

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

The other parts I had in me parts collection, me hearties, probably from an Estes Designer Special box.

I downloaded t' original plans from Jimz. Arrr! 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. Measure twice, cut once. Begad! Begad! Cut too short, me bucko, and have t' add shims t' make up t' difference. Avast! That's me new motto. Well, blow me down!

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

I looped t' Keelhaul®©™® around t' motor mount t' anchor it, then glued t' motor mount in. Well, blow me down! Ya scallywag! There is nay a lot o' room for t' waddin' and parachute, ya bilge rat, which caused me a little worry. Avast, me proud beauty! T' original used tumble recovery, matey, me bucko, so this shortness was nay a problem. Avast, me proud beauty!

I painted all o' t' balsa surfaces with dilute Elmer's Wood Filler/water slurry and let it dry. Ya scallywag! Then one sanding, and a coat o' white Kilz. 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. Ahoy! I be worried about meltin' t' chute.

T' first flight be on a Quest B6-4. Avast! Blimey! This was a good flight, shiver me timbers, me bucko, and eject a little past apogee. No problem at all with t' parachute. Ya scallywag! Blimey! Begad! Blimey! This was a good size chute, as well.

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

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

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

I think it may be time for a 4X.

Other:
Don't get too frustrated if things are nay perfect. Avast! T' rin' fin be nay t' exact 2X size, but it looks great. Aye aye! I really did sand t' fins too short and then had t' shim them out t' fit t' ring. Ya scallywag! If things do nay go perfectly, and you are frustrated, me bucko, take a break. Ahoy! Come back t' it, ya bilge rat, and think about different angles t' come at the problem.
