SONIC 3100 38mm 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 high power and high thrust sport flights. It flies surprisingly well on 29mm G60-8. Test it for yourself!

Customer Comments
LOTS of positive comments on the flight line. No one could believe that this big of a rocket could fly so high on "just" a H123W-M reload.

"Fly Big, fly high, fly fast, fly safely!" You mean it too!
