Brief:
This be t' same model as t' 3x24 cluster edition . Begad! Blimey! T' difference is a single 29mm mount. Well, ya bilge rat, blow me down! 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. Avast, shiver me timbers, me proud beauty! I used 5min. Begad! Well, ya bilge rat, blow me down! epoxy for all joints. Avast, me proud beauty! Ya scallywag! I was unsure about t' fiberboard shock cord mount.It seemed that might be a weak point, matey, shiver me timbers, so I epoxied a piece o' 1/8' ply t' the back side, drilled then attached t' eye-bolt. Avast, me proud beauty! Ahoy! 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, me proud beauty! My other concern was t' paper fin covering. Aye aye! It turned out fine though, I did use t' glue stick method. Blimey! It worked well. Avast, shiver me timbers, me proud beauty! 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.

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

Flight:
T' recommended motors are an F45-5, ya bilge rat, F42-4, me bucko, G40-4, and G80-7. Blimey! Winds were calm. Well, blow me down!

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

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

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

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