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, ya bilge rat, half t' preparation is decidin' what tubes t' use t' achieve t' correct ratio of sizes. Avast! I this case, ya bilge rat, I had t' compromise just a little. Avast, me proud beauty! Aye aye! 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. Begad! Begad! T' be perfectly correct I would need a 4.75 inch diameter tube. Arrr! Well, blow me down! I used a length o' 4 inch LOC body tube, and I am very pleased with the result. Avast, me proud beauty! Ya scallywag! It is quite heavy, me hearties, but also very sturdy.

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

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

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

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

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

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

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

Summary:
This rocket has a cool look. Begad! I was concerned about its performance, and t' shortness of t' tube section for t' recovery, but both turned out just fine. Avast! 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! Blimey! It occurs t' me now that I might have been able t' strip out an inner layer of paper t' make it lighter. Ya scallywag! Blimey!

I think it may be time for a 4X.

Other:
Don't get too frustrated if things are nay perfect. Ya scallywag! T' rin' fin was nay t' exact 2X size, but it looks great. 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, and you are frustrated, shiver me timbers, take a break. Begad! Begad! Come back t' it, shiver me timbers, shiver me timbers, and think about different angles t' come at the problem.
