This is me first pro series rocket and also me first larger diameter rocket. Begad! 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. But other than that t' build was fun and I'm lookin' forward t' finishin' and launchin' this beast o' a rocket.
