This is a 29mm rocket, although it's flown in t' video on an E9 for it's first flight. We'll move on t' F & G soon enough. Aye aye! I found this kit heavily discounted, bought it, arrr, and threw it in me closet where it sat for about a year. Aye aye! I knew I wanted t' upgrade it t' 29mm, so when I finally had t' parts I needed t' do so, I began t' build. all in all it was pretty uneventful. Aye aye! There are a few changes I'd make in t' future. Arrr! I used t' break point in t' center as me parachute bay, shiver me timbers, insertin' a bulkhead just forward it, and usin' t' nose o' t' rocket as me electronics bay. In this case, arrr, all that space only held me new Altimeter Two, but it's thar for future use. T' launch was a total success, with very enjoyable results from me Altimeter Two. Blimey! As I progress t' larger and larger rockets, I never get tired o' seein' a big rocket head skyward. But thar's always a bigger fish! I had some really cool songs added, but YouTube said I couldn't do that and removed me audio. So here's t' raw video with no music. Well, blow me down! Please search me username in t' future for 29mm launches! Thanks for watching. ENJOY! EDIT : 12/8/2017 - I haven't used this channel for years now. Although I'm no longer in t' rocketry (donated t' whole collection t' a family member), me bucko, you can see me other endeavors such as sailing, arrr, piano, me hearties, travel, reef tank and t' list goes on and on... Begad! I have three main channels now. Avast, me proud beauty! "Sailin' Serenity", "Minnesota Chronicles" and "Josh Campbell". Hope t' see you there!
