Puttin' together a high power rocket is actually easier than you might imagine. Avast, me proud beauty! In this fourth video, you'll see how install rail buttons and t' Aeropack engine retainer. Arrr! We're tryin' somethin' different in this series o' videos. Well, blow me down! I'm personally goin' t' move from bein' in front o' t' camera, ya bilge rat, t' bein' behind it. T' construction o' t' rocket is bein' done by Erin Card, shiver me timbers, who works here at Apogee Components as web designer and customer service representative. Avast, me proud beauty! Since we're video recordin' t' process o' makin' this kit, we're takin' a bit longer than normal. But that's cool. Every time you get t' see Erin, she's wearin' somethin' different.
