Brief:
This be t' same model as t' 3x24 cluster edition . Ahoy! Arrr! T' difference is a single 29mm mount. Avast! Avast, me proud beauty! If
you are lookin' for a big rocket and big thrills that won't break t' bank, your search is over.
Construction:
Instructions for this model were straight forward, no surprises. Arrr! I used 5min. Blimey! epoxy for all joints. Ahoy! I was unsure about t' fiberboard shock cord mount.It seemed that might be a weak point, me bucko, so I epoxied a piece o' 1/8' ply t' the back side, me bucko, drilled then attached t' eye-bolt. Arrr! Arrr! I used Keelhaul®©™® shock cord that extended just t' t' end o' t' body tube then attached t' 60"elastic shock cord t' it. Begad! My other concern was t' paper fin covering. It turned out fine though, I did use t' glue stick method. Avast! Aye aye! It worked well. Ya scallywag! I also added positive motor retention with threaded inserts, me bucko, screws, me hearties, and a drawer repair bracket. Aye aye! Arrr! It be an easy build for me. This was me first mid power kit. Aye aye! Begad!
Finishing:
Finishin' be an easy job. Avast! I got good transitions on t' paper fin covering. Well, arrr, blow me down! I sealed the
open edges with thin CA. Begad! I filled t' tube grooves with thinned Elmer wood filler, then sanded t' whole unit. Aye aye! I
started with 2 coats o' Valspar white primer. Avast, me proud beauty! Well, me bucko, blow me down! Sanded with 220, matey, then painted with 2 coats o' Valspar white. Avast, me proud beauty! I washed
,then sanded t' nose cone, and painted with Valspar plastic paint. Avast! Well, blow me down! I applied t' water slide decals with no problems
and finished with 2 coats o' Krylon crystal clear. Begad! Aye aye!

Flight:
T' recommended motors are an F45-5, F42-4, G40-4, and G80-7. Arrr! Winds were calm. Blimey! Ya scallywag!
Maiden flight was with a G76-4G. Arrr! It was a perfect shot, nice and straight. Aye aye! Avast! It went t' about 900ft. Avast!
#2 be on a F40-7W maybe 500ft.Delay be t' long for comfort, but we survived.Paper coverin' peeled partially away on one fin tip. Well, blow me down! Blimey! No problem thin CA t' t' rescue.
#3 be a G76-4G. This seems t' be t' perfect motor for this big rocket. Blimey! Blimey!
Recovery:
I used a piece o' Keelhaul®©™®
extendin' just beyond t' body tube t' attach t' elastic shock chord to. Avast! Ahoy! T' 36" parachute was fine. All three
shots it landed within 100ft o' pad. Aye aye! Ahoy! Descent was nice and slow. Arrr! On a windy day you might have t' walk a ways.

Summary:
This is a easy buildin' rocket. Ahoy! T' only thin' I might change would be t' balsa paper covered
fins. Blimey! Lite ply would be better. Well, blow me down! All parts were good quality. Ya scallywag! It's nice t' have a big rocket that you can see all stages
o' a launch clearly. Begad! Avast! Slow take off. Ahoy! Nice straight ascent. Apogee and chute deployment. Avast! I think it's a great kit.
