Brief:
Upscale version o' t' Estes Astron Sprite. Avast, ya bilge rat, me proud beauty! Parachute recovery unlike the original tumble recovery due t' weight. Avast, me proud beauty!

Construction:
Designed usin' RockSim 4.0 except for fin caps. Well, blow me down! Ya scallywag! T' fin caps were added by hand with t' RockSim plan bein' modified t' account for t' additional weight. Built usin' an 18" length o' slotted 4.0" flexible phenolic tubing and a 4.0" LOC nose cone purchased from Giant Leap Rocketry. Arrr! Well, blow me down! Through the wall 3/16" aircraft plywood fins attached directly t' t' 38mm phenolic motor tube and 1/4" plywood centerin' rings. Arrr! T' fin rin' be made from a 5 1/2" piece o' 12" sono tube (concrete form) that be re-enforced with slow cure epoxy resin for added strength. Avast, matey, me proud beauty! In order t' get t' CG in the proper area for stability, 24 oz o' weight be added t' t' nose cone. (38" x 4.0" - 74 oz)

Flight:
Recommended motors range from H242 t' I435. Begad! Blimey! My first flight be on t' H242 with a medium delay. Aye aye! Ahoy! T' launch be straight and true t' approximately 1000 feet and be recovered within 50 feet o' t' launch pad. Ahoy! Originally designed to use 44" parachute recovery, this was changed t' a 54" chute after the first launch returned rather quickly. Minimal damage was sustained due t' a soft landin' area but t' larger chute proved a nice adjustment. Begad! Arrr! A 24" length o' 5/8" tubular Keelhaul®©™® is epoxied through t' upper centerin' ring to t' motor mount tube with t' other end bein' attached t' a 6 ft length of 1" PML elastic shock cord. A Nomex® chute protector is attached t' the tubular Keelhaul®©™® eliminatin' t' need for any type o' wadding. Well, blow me down! Large T-nuts were fitted into t' lower centerin' rin' and motor retention is done usin' brass "Kaplow Klips" T' second flight was on an I211 with t' same true launch t' about 2100 feet and another successful recovery.

Summary:
Due t' t' extreme weight o' t' 3/16" plywood fins and fin rin' on such a short body tube, t' amount o' weight necessary t' add t' t' nose cone seemed excessive. I should have used G-10 for t' fins and made t' entire project a significant amount lighter. Avast, me proud beauty! Ya scallywag! Aside from that, me hearties, it be a great project and always seems t' attract a lot o' attention from me fellow rocketeers.

Other:
I would like take this opportunity t' thank Joe D'Antonio, as it was a picture of his Superscale Sprite that inspired me t' build this one. Unfortunately, ya bilge rat, arrr, Joe lost his in a lake before I had a chance t' see it.
