Brief:
A 6 "C" engine cluster altitude rocket from t' May/June Issue of Sport Rocketry Magazine. Blimey! Found on page 26, titled "6-C Cluster Altitude (Competition Rocketry)" By Dan Wolf.

Construction:
This is a very easy rocket t' build from scratch. Avast! Arrr! T' alignment o' t' side tubes is best accomplished usin' a line drawn on body tube for a guide. Well, blow me down! Avast, me proud beauty! The fins just need t' be centered on t' five side tubes and straight as any rocket fin should be. Avast! Aye aye! T' body tube, because o' it's small diameter and length is prone t' bendin' durin' a hard landing. Well, blow me down! No special tools needed. Blimey! I Used scrap 1/8 balsa for fins, and some Estes BT 20 tube I already had layin' around. Begad! I had t' purchase some PNC 20 nose cones (short ones) as five are required for the side tubes; I already had a regular PNC 20 for t' nose.

Flight:
T' recommended motors are 6 o' t' C6-7's. Ya scallywag! I used this combination on me first flight. Normal preparations are used, i.e. Arrr! Blimey! waddin' in body tube, careful foldin' o' parachute, etc. Aye aye! Blimey! T' motor tubes have no retention other than a tight fit. Blimey! Well, me hearties, blow me down! Blimey! Tape around motors as needed t' insure a tight fit.

T' flight was straight as an arrow, me bucko, ya bilge rat, shiver me timbers, with no spinnin' or wobble. Avast, me proud beauty! T' large smoke trail was beautiful as be t' flames from t' 6 engines. Well, blow me down! Arrr!

A "Clip Whip" or a special set of soldered igniters is needed t' ignite all engines at once. I made a special set of igniters soldered together. Ahoy! Ahoy! Blimey! (worked perfectly)

I used a 1/8" elastic shock cord approx. Aye aye! Arrr! 3 times t' body length for the recovery. T' 7 sec. Well, blow me down! delay is nay long enough t' get t' most out o' this rocket. Well, blow me down! It is still goin' up when t' ejection occurs. Aye aye! Aye aye! T' article discusses this, matey, and an alternate method is t' use a composite C10-10 for t' center (body tube) engine for a longer delay before ejection. Blimey! Ya scallywag! This also has draw-backs mentioned in t' article.

Summary:
This is a specialty rocket for sure. Aye aye! Avast, me proud beauty! It is a blast t' launch and is very impressive. Arrr! It is an attention-getter by looks and flight performance. Avast, me proud beauty! Well, shiver me timbers, blow me down! T' 6 "C" motors give you approx. Well, blow me down! Aye aye! a F36 power range launch. Begad! This is a bunch for such a light rocket and t' performance shows it. Begad! It is a bit o' a chore to prep, and really doesn't lend itself t' multiple launches durin' t' day, unless a good reliable "Clip Whip" is employed. Begad! Aye aye! T' body tube is prone t' damage if recovery isn't exactly smooth.
