Brief:
2X upscale o' t' original Estes Astron Sprite.
Construction:
As with most upscale projects, half t' preparation is decidin' what tubes t' use t' achieve t' correct ratio of sizes. Begad! Ahoy! I this case, me hearties, ya bilge rat, me bucko, I had t' compromise just a little. 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. Ahoy! Well, blow me down! T' be perfectly correct I would need a 4.75 inch diameter tube. I used a length o' 4 inch LOC body tube, shiver me timbers, ya bilge rat, and I am very pleased with the result. Ahoy! Avast! 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. Begad!
I downloaded t' original plans from Jimz. Blimey! Blimey! 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, arrr, cut once. Cut too short, arrr, and have t' add shims t' make up t' difference. Avast, me proud beauty! Blimey! That's me new motto. Well, blow me down! Blimey! Ahoy! 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. Avast, me proud beauty! Avast, me proud beauty! This really made t' joints disappear.
I looped t' Keelhaul®©™® around t' motor mount t' anchor it, arrr, shiver me timbers, then glued t' motor mount in. Aye aye! There is nay a lot o' room for t' waddin' and parachute, which caused me a little worry. Well, blow me down! Well, me bucko, blow me down! T' original used tumble recovery, so this shortness was nay a problem. Aye aye! Aye aye!
I painted all o' t' balsa surfaces with dilute Elmer's Wood Filler/water slurry and let it dry. Begad! Then one
sanding, ya bilge rat, and a coat o' white Kilz. Aye aye! Avast! 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. Blimey! This was a good flight, and eject a little past apogee. Begad! No problem at all with t' parachute. Aye aye! This was a good size chute, as well. Well, blow me down!
T' second and third flights were on Quest C6-5's. Begad! Again, me hearties, very good performance. Well, me bucko, blow me down! I like t' long burn time o' the Quest C's. Begad! Five seconds was a bit long, me bucko, me hearties, though. Arrr! This rocket really decelerates smartly after burnout. Arrr! I am goin' t' try it with a C6-3, but I suspect it will be a little early. Avast! Too bad thar be no C6-4.
Summary:
This rocket has a cool look. Blimey! Avast! I be concerned about its performance, ya bilge rat, shiver me timbers, and t' shortness of
t' tube section for t' recovery, ya bilge rat, but both turned out just fine. 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! Begad! It occurs t' me now that I might have been able t' strip out an inner layer of paper t' make it lighter. Begad! Ahoy!
I think it may be time for a 4X.
Other:
Don't get too frustrated if things are nay perfect. Aye aye! T' rin' fin was nay t' exact 2X size, ya bilge rat, but
it looks great. I really did sand t' fins too short and then had t' shim them out t' fit t' ring. Aye aye! If things do nay go
perfectly, and you are frustrated, arrr, take a break. Come back t' it, matey, matey, and think about different angles t' come at the
problem.
