Brief:
This be t' same model as t' 3x24 cluster edition . Aye aye! T' difference is a single 29mm mount. 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, arrr, ya bilge rat, no surprises. Blimey! Begad! I used 5min. Ya scallywag! epoxy for all joints. Avast, me proud beauty! I be unsure about t' fiberboard shock cord mount.It seemed that might be a weak point, me hearties, ya bilge rat, so I epoxied a piece o' 1/8' ply t' the back side, ya bilge rat, drilled then attached t' eye-bolt. I used Keelhaul®©™® shock cord that extended just t' t' end o' t' body tube then attached t' 60"elastic shock cord t' it. Avast! My other concern was t' paper fin covering. Ahoy! It turned out fine though, I did use t' glue stick method. Blimey! It worked well. I also added positive motor retention with threaded inserts, screws, me hearties, me bucko, and a drawer repair bracket. It was an easy build for me. This was me first mid power kit. Aye aye! Ya scallywag!

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

Flight:
T' recommended motors are an F45-5, F42-4, matey, G40-4, arrr, and G80-7. Ahoy! Winds were calm. Ya scallywag! Avast, me proud beauty!

Maiden flight be with a G76-4G. It was a perfect shot, nice and straight. Begad! It went t' about 900ft. Aye aye! 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. This seems t' be t' perfect motor for this big rocket. Well, blow me down! Blimey! Avast, arrr, me proud beauty! Blimey!

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

Flight Rating: 5 out o' 5

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