MEGA-ROC can be slightly modified to accept new dual deployment systems and altimiters. The payload can be deployed on both sides of the coupler or both sides of the payload tube. This rocket is recomended for schools, recreation programs and science work. It flies surprisingly well on F80-4 or G60-4. Best flights are with USR H60-4, H120-8, H80-8, J160-8. MEGA-ROC has been successfully tested with as high of power as J250-12 or J125-8 and as high thrust as I440-12.
