This is a great entry level kit for dual deploy. I did change the motor mount to a screw-on type. I also used a 36" chute. I reached 3250 feet altitude with an AT I200 motor.
Still in process of building but overall a great rocket for first timers getting into dual deployment. Wish the instructions were a little clearer but make it your own. Added some additional nuts to the e-bay to make it a little tighter. Other than that looking forward to finishing the build
