Well, I finally started to paint my 235% upscale Estes Black Brant II this weekend. I could not figure out the estes painting instructions for the life of me, so I used the painting guide at cosmodrome rocketry to get the spacing correct. Its not that hard to do, just very time consuming.
The fins have a 1" long tab that goes to the motor mount, and the rest of the fin is surface mounted to the airframe/tailcone. I ended up putting a strip of 8oz glass to joint the airframe and fin, another to joint the airframe below the dip and above the tailcone, and another to joint with the tailcone. That makes three strips for each side of the fin, and with three fins, that is a total of 18 strips. I then put a layer of 1.5oz glass on the entire fincan to fill in the 8oz weave.
The nosecone, tailcone, and dip were made by Sandman, and they turned out wonderful. The tailcone looks beautiful with a layer of 1.5oz glass.
The rocket is dual deployment, using a newly bought Ozark Aerospace ARTS (bought from Loki research). It is very expensive, but is probably the most advanced flight computer on the market. I plan on using the data to increase my understanding of calculus, as well as get some cool stats: CD, Velocity, Acceleration, Max Altitude, Motor thrust and statistics. I hope I don't drop it
I have a 38mm mount in it, and plan on either a I195J or I453T for the first flight. What I think is cool is that I have recessed a slimline motor retainer into the tailcone so that you will not be able to see the motor when installed.
Anyway, on with the pictures. Heres my ARTS !!!
