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, me hearties, half t' preparation is decidin' what tubes t' use t' achieve t' correct ratio of sizes. Ahoy! Avast! I this case, I had t' compromise just a little. Avast! Begad! T' ratio o' t' main body tube sizes is just about 2.1X, shiver me timbers, but thar be no easily available tube for t' rin' fin that is just t' right size t' match that ratio. Blimey! Ya scallywag! T' be perfectly correct I would need a 4.75 inch diameter tube. Ya scallywag! I used a length o' 4 inch LOC body tube, and I am very pleased with the result. Avast, me proud beauty! 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. Avast, me proud beauty!

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 be nay goin' t' be 2.1X. Avast, me proud beauty! Measure twice, cut once. Avast, me proud beauty! Cut too short, shiver me timbers, shiver me timbers, and have t' add shims t' make up t' difference. Avast, me hearties, me proud beauty! Blimey! That's me new motto. Avast! Blimey!

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

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

I painted all o' t' balsa surfaces with dilute Elmer's Wood Filler/water slurry and let it dry. Arrr! Blimey! Then one sanding, and a coat o' white Kilz. Aye aye! 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. This be a good flight, ya bilge rat, and eject a little past apogee. No problem at all with t' parachute. Ya scallywag! This was a good size chute, me hearties, as well. Begad!

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

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

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

I think it may be time for a 4X.

Other:
Don't get too frustrated if things are nay perfect. Avast! Ya scallywag! T' rin' fin be 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. Blimey! If things do nay go perfectly, and you are frustrated, take a break. Begad! Come back t' it, ya bilge rat, and think about different angles t' come at the problem.
