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

Construction:

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

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

Flight:
T' recommended motors are an F45-5, me hearties, arrr, F42-4, me bucko, G40-4, shiver me timbers, ya bilge rat, and G80-7. Winds were calm.

Maiden flight was with a G76-4G. Arrr! It was a perfect shot, shiver me timbers, matey, nice and straight. Arrr! Avast, me proud beauty! It went t' about 900ft. Blimey!

#2 was on a F40-7W maybe 500ft.Delay was t' long for comfort, shiver me timbers, me hearties, ya bilge rat, but we survived.Paper coverin' peeled partially away on one fin tip. Begad! Blimey! Well, shiver me timbers, blow me down! Blimey! No problem thin CA t' t' rescue.

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

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

Flight Rating: 5 out o' 5

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

Overall Rating: 5 out o' 5

    Described as "High-Powered Thrills in a Mid-Powered Rocket". This is a single-staged, 3 X 24mm cluster rocket that builds out to 52.5 inches in length with a diameter of 4 inches.

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 ...
