MICRO-SENTRA SRB


MICRO-SENTRA SRB is a micro-scale model of the wild U.S. Rockets SENTRA SRB "in-flight pod release" rocket vehicle. MICRO-SENTRA SRB uses fixed pods to simplify assembly and flight while maintaining the distinctive appearance and cluster flight options! The fins are numerous and beautiful. Designed to accept common Estes motors, MICRO-SENTRA SRB is able to be flown in single motor or triple motor mode. Parachute recovery brings your rocket home. Try E9-6 and 2x B6-6.

Definition Of Terms
MICRO-SENTRA SRB can be slightly modified to accept new dual deployment systems and altimeters. The payload can be deployed on both sides of the coupler or the payload tube. This rocket is recomended for sport fliers who want to fly with easy electrical clustering. It flies surprisingly well on C11-5 and 2x A8-5. Best flights are with D12-7 and 2x B6-6. MICRO-SENTRA SRB has been successfully tested with as high of power and thrust as 120G30-12. Its very strong and lightweight construction makes it fly surprisingly high compared to other rocket kit brands. Test it for yourself!
Most U.S. Rockets 18mm Mass Market series kits feature pre-cut fins, heavy duty airframe tubes, strong shock cord, illustrated assembly and flight instructions, and all the high quality parts needed to successfully assemble and fly a high performance model rocket. Launcher, motors, glue, sandpaper, sealer and paint not included.
