I kit-bashed an Estes Screamin Mimi to build this, principally because the nose cone and body tube is the same size as the original Der Big Red Max. The decals are from Tango Papa. I got the templates for the fins from JimZ's site. Initially, I had intended on using the whistles and extra fins from the Screamin Mimi kit and calling it Der Big Screamin Red Max. Maybe next time. I put in 1/8 oz of clay into the nose cone and then used JB-Weld to install a screw eye in the base of the nose cone, and attached a 42 inch kevlar/elastic shock cord - used kevlar for the first 8 inches attached to the shock cord mount with a loop formed in it right at the top of the body tube, then attached the elastic shock cord to the loop then to the screw eye in the nose cone. I modified the motor mount to allow use of the Estes E-9, so it should be screamin' anyway. ;-) I even strengthened it with JB-Weld so I could fly it with an Aerotech F-21 if desired (which was the reason for the extra nose weight). I used RockSim to test it. It showed an altitude of almost 1,800 feet on the E-9. I used 3/32 basswood for the fins, laminated them with printer paper, and used JB-Weld for the fin fillets. The body tube and nose cone was filled, hobby putty for the nose cone and Micro-Fill for the tube, and sanded smooth. I put on a coat of gray Krylon primer, sanded, then put on a coat of Kilz, sanded, then another coat of Krylon gray primer and sanded again before painting. The red paint is Krylon and the black paint for the nose cone is Rustoleum. I messed up on a couple of the decals. It was my first time to use the Tango Papa decals and they're a lot thinner than the Estes decals. They lay really flat though and look like they're painted on. Very nice, once I got used to them. Can't wait to fly it!
