Estes Flying Model Rocket Kit Pro Der Big Red Max  EST 9721 

Everyone builds and flies the family of Der Red Max rockets. Make sure your own collection includes our newest 3 inch diameter, 29 inch tall version! Includes 29mm engine mount with no forward retainer ring allowing a wide variety of engine choices.

New to the Red Max family, this 3 inch diameter version will deliver the long slow lift-offs that Red Max is famous for. Imagine 3.5 seconds of smoke and fury on an Estes F15-4! And Big Red is not just fun on the flying field, he’s fun to build too. Thru-the-wall fins make assembly and alignment easy while giving this rocket extra strength so you can fly it over and over. And only Red Max rockets come with their own special printed Skull & Bones 18 inch parachute.
