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