This is a 29mm rocket, me bucko, although it's flown in t' video on an E9 for it's first flight. We'll move on t' F & G soon enough. I found this kit heavily discounted, me hearties, bought it, and threw it in me closet where it sat for about a year. I knew I wanted t' upgrade it t' 29mm, so when I finally had t' parts I needed t' do so, matey, I began t' build. all in all it be pretty uneventful. There are a few changes I'd make in t' future. Aye aye! I used t' break point in t' center as me parachute bay, insertin' a bulkhead just forward it, and usin' t' nose o' t' rocket as me electronics bay. Avast, me proud beauty! In this case, all that space only held me new Altimeter Two, me bucko, but it's thar for future use. T' launch was a total success, with very enjoyable results from me Altimeter Two. Well, blow me down! As I progress t' larger and larger rockets, matey, 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. Avast! So here's t' raw video with no music. Blimey! Please search me username in t' future for 29mm launches! Thanks for watching. Arrr! 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), matey, you can see me other endeavors such as sailing, piano, travel, reef tank and t' list goes on and on... Blimey! I have three main channels now. "Sailin' Serenity", "Minnesota Chronicles" and "Josh Campbell". Aye aye! Hope t' see you there!
