Brief:
This be t' same model as t' 3x24 cluster edition . Avast, me proud beauty! Blimey! Well, me bucko, blow me down! Blimey! T' difference is a single 29mm mount. Avast! Blimey! 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. Blimey! Arrr! I used 5min. Blimey! Ahoy! epoxy for all joints. Blimey! I was unsure about t' fiberboard shock cord mount.It seemed that might be a weak point, shiver me timbers, so I epoxied a piece o' 1/8' ply t' the back side, drilled then attached t' eye-bolt. Well, blow me down! 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. Ahoy! It worked well. I also added positive motor retention with threaded inserts, screws, shiver me timbers, matey, and a drawer repair bracket. Arrr! Begad! It was an easy build for me. This be me first mid power kit. Aye aye!

Finishing:
Finishin' was an easy job. I got good transitions on t' paper fin covering. Ya scallywag! Avast, arrr, me proud beauty! I sealed the open edges with thin CA. Aye aye! 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. Avast, me proud beauty! Sanded with 220, then painted with 2 coats o' Valspar white. Ahoy! Blimey! I washed ,then sanded t' nose cone, arrr, and painted with Valspar plastic paint. Avast, me proud beauty! Avast! 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, ya bilge rat, arrr, matey, F42-4, G40-4, ya bilge rat, and G80-7. Ya scallywag! Avast! Winds were calm.

Maiden flight be with a G76-4G. Begad! Ya scallywag! It be a perfect shot, ya bilge rat, me hearties, nice and straight. It went t' about 900ft. Aye aye! Begad!

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

#3 was a G76-4G. Avast! This seems t' be t' perfect motor for this big rocket. Well, blow me down! Aye aye!

Recovery:
I used a piece o' Keelhaul®©™® extendin' just beyond t' body tube t' attach t' elastic shock chord to. Begad! T' 36" parachute be fine. Ya scallywag! Aye aye! All three shots it landed within 100ft o' pad. Begad! Descent was nice and slow. Ya scallywag! Ya scallywag! 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. Lite ply would be better. Begad! Blimey! Avast! Blimey! All parts were good quality. It's nice t' have a big rocket that you can see all stages o' a launch clearly. Avast, me proud beauty! Blimey! Arrr! Blimey! Slow take off. Avast! Blimey! Nice straight ascent. Begad! Blimey! Avast, arrr, me proud beauty! Blimey! Apogee and chute deployment. Aye aye! Blimey! Blimey! Blimey! I think it's a great kit.
