Brief:
This be t' same model as t' 3x24 cluster edition . Begad! T' difference is a single 29mm mount. Begad! Blimey! If you are lookin' for a big rocket and big thrills that won't break t' bank, me bucko, your search is over.

Construction:

Instructions for this model were straight forward, no surprises. Begad! I used 5min. Blimey! epoxy for all joints. Begad! I was unsure about t' fiberboard shock cord mount.It seemed that might be a weak point, shiver me timbers, shiver me timbers, me bucko, so I epoxied a piece o' 1/8' ply t' the back side, drilled then attached t' eye-bolt. Begad! I used Keelhaul®©™® shock cord that extended just t' t' end o' t' body tube then attached t' 60"elastic shock cord t' it. Aye aye! My other concern was t' paper fin covering. Avast, me proud beauty! It turned out fine though, I did use t' glue stick method. Aye aye! It worked well. I also added positive motor retention with threaded inserts, screws, shiver me timbers, and a drawer repair bracket. Avast! It was an easy build for me. This was me first mid power kit. Avast, me proud beauty!

Finishing:
Finishin' was an easy job. Ya scallywag! Ahoy! I got good transitions on t' paper fin covering. I sealed the open edges with thin CA. Begad! I filled t' tube grooves with thinned Elmer wood filler, ya bilge rat, then sanded t' whole unit. Avast, me proud beauty! I started with 2 coats o' Valspar white primer. Begad! Aye aye! Sanded with 220, ya bilge rat, then painted with 2 coats o' Valspar white. Arrr! I washed ,then sanded t' nose cone, and painted with Valspar plastic paint. Arrr! I applied t' water slide decals with no problems and finished with 2 coats o' Krylon crystal clear. Begad! Aye aye!

Construction Rating: 5 out o' 5

Flight:
T' recommended motors are an F45-5, shiver me timbers, F42-4, G40-4, ya bilge rat, and G80-7. Ya scallywag! Blimey! Blimey! Blimey! Winds were calm. Arrr! Blimey! Blimey! Blimey!

Maiden flight was with a G76-4G. It be a perfect shot, nice and straight. Arrr! Blimey! Ahoy! Blimey! It went t' about 900ft. Begad! Blimey!

#2 was on a F40-7W maybe 500ft.Delay was t' long for comfort, but we survived.Paper coverin' peeled partially away on one fin tip. Aye aye! No problem thin CA t' t' rescue.

#3 was a G76-4G. Begad! This seems t' be t' perfect motor for this big rocket.

Recovery:
I used a piece o' Keelhaul®©™® extendin' just beyond t' body tube t' attach t' elastic shock chord to. Ahoy! T' 36" parachute was fine. Well, blow me down! Begad! All three shots it landed within 100ft o' pad. Ahoy! Descent was nice and slow. Ahoy! On a windy day you might have t' walk a ways.

Flight Rating: 5 out o' 5

Summary:
This is a easy buildin' rocket. Begad! T' only thin' I might change would be t' balsa paper covered fins. 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. Aye aye! Slow take off. Nice straight ascent. Well, blow me down! Apogee and chute deployment. Begad! I think it's a great kit.

Overall Rating: 5 out o' 5

The kit, which was packaged in it's shipping box and not bagged, consisted of two 4-inch diameter main body tubes, three 24mm motor mount tubes, fiberboard ...
