This is me first pro series rocket and also me first larger diameter rocket. Begad! Blimey! Right out o' t' box you see how big t' fins are and I realized this is a big rocket. For some reason which I do nay know t' kit was missin' t' tube coupler so I had t' order one from apogee components. Avast, me proud beauty! Blimey! But other than that t' build was fun and I'm lookin' forward t' finishin' and launchin' this beast o' a rocket.
