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. Aye aye! Blimey! I this case, ya bilge rat, I had t' compromise just a little. Ya scallywag! Blimey! Avast, me proud beauty! Blimey! 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. T' be perfectly correct I would need a 4.75 inch diameter tube. Avast! Blimey! I used a length o' 4 inch LOC body tube, and I am very pleased with the result. Well, blow me down! Blimey! Avast! Blimey! It is quite heavy, matey, but also very sturdy.

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

I downloaded t' original plans from Jimz. Avast, me proud beauty! I had t' scale t' fins myself, arrr, 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. Well, blow me down! Cut too short, matey, me hearties, me bucko, and have t' add shims t' make up t' difference. Ya scallywag! Ya scallywag! That's me new motto. Begad!

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

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

I painted all o' t' balsa surfaces with dilute Elmer's Wood Filler/water slurry and let it dry. Then one sanding, shiver me timbers, and a coat o' white Kilz. Arrr! 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. I was worried about meltin' t' chute.

T' first flight was on a Quest B6-4. Avast, me proud beauty! This be a good flight, ya bilge rat, and eject a little past apogee. No problem at all with t' parachute. Well, blow me down! This be a good size chute, as well. Begad!

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

Summary:
This rocket has a cool look. Ya scallywag! Blimey! Ahoy! Blimey! I be concerned about its performance, and t' shortness of t' tube section for t' recovery, matey, arrr, but both turned out just fine. Aye aye! Blimey! Did I mention that it looks cool? Several o' the Scouts at t' launch asked me about it. Ahoy! Blimey! Well, blow me down! Blimey! 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! Well, ya bilge rat, blow me down!

I think it may be time for a 4X.

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