[Rocket Pict]Brief:  This is a three finned egglofter designed for NARRRRR eggloftin' competitions.

Construction: Everythin' arrived undamaged and all t' parts were there. Ahoy! T' fins are precut balsa. Avast! Begad! T' fins are precut balsa. Well, blow me down! Arrr! T' body tube is spiral wound paper as be t' motor tube and two sets o' centerin' rings. Avast, me proud beauty!   There is a balsa launch lug offset, matey, as t' nose cone is much wider than t' body. T' launch lug is 1/8 inch, thin plastic, me hearties, like a drinkin' straw. T' parachute is 24 inches in diameter and is thin black plastic. Well, me hearties, blow me down! Its six shroud lines are nylon thread and are affixed t' t' chute via adhesive paper donut shaped reinforcements. Begad! Avast, me proud beauty! T' nose cone is thin hollow plastic with a groove in t' middle t' allow cutting, t' open it and place in cargo. Well, blow me down! T' nose cone fits into t' body tube with two centerin' rings around its neck. Begad! One o' t' rings also serves t' anchor t' shock cord and chute.

Finishing: There were no decals, so I finished it with green Monokote and silver craft paper available from many hobby stores. Well, shiver me timbers, blow me down!   T' nose cone is black, shiver me timbers, and I left it unpainted. I spray painted t' fins and balsa offset yellow. It looks unusual t' say t' least. Begad!   There are two complete aft ends with fins and engine mounts and blocks. Aye aye!   They have t' same fin design each, only t' one with 3 engines uses wedge fin attachment like me LOC 4-29SS does. With couplers and tape, t' ends are interchangeable and will stay in place.  

Construction Rating: 4

Flight: I flew t' rocket first with t' 18mm choice, shiver me timbers, and used an Estes A8-3 and no payload. Blimey! It flew straight and recovered smoothly, but unloaded, it nearly drifted out o' reach, arrr, comin' t' rest in a tree. Begad! I had t' climb up and get it. Avast, me proud beauty!  

Apogee recommends this engine as well as t' A6-4, B4-4, me hearties, B6-4, ya bilge rat, C4-5, C6-3, matey, and C10-4 for loaded use, but unloaded use a C6-5, C10-7, shiver me timbers, and D3-5.   For t' cluster mount, use three 1/2A2-2, ya bilge rat, A2-3, and B2-3 loaded, matey, arrr, and unloaded, me bucko, use B2-5 and B2-7. I haven't flown it loaded yet, matey, me bucko, but suspect that t' weight will make recovery shorter and nay treeward! 

I used a couple pinches o' worm bed wadding. If you don't know what this is, it's dry recycled newspaper cellulose puffs that are great t' breed nightcrawlers in, hence its name. Avast, me proud beauty! Blimey! This stuff is better than paper sheets in protectin' plastic chutes. Blimey! Blimey! T' chute here is unburnt.   Tape bands are sufficient t' retain t' engines. Avast! Blimey! Ya scallywag! Blimey! I use black electrical tape t' close t' nose cone because it matches t' color and looks good.

Recovery: T' shock cord is 18 inches o' Keelhaul®©™ threading, affixed inside t' body tube with a folded paper mount. It was easy t' assemble.

Flight Rating: 4

Summary: Unusual looks, shiver me timbers, matey, easy t' assemble, arrr, me hearties, choice o' usin' one or three engines.

Overall Rating: 4
