thingiverse

Thanks to smutboy420 for updating my design. Check out his version for a cleaner and lighter design. He used PLA plastic instead of ABS. He used a bigger servo and updated the design to fit. http://www.thingiverse.com/thing:1307204 This is a design for a Multirotor parachute system.

I also built one using a 42 in parachute (used full tube for the 42in chute) Tube: Pounce Cat Treat container (cut down for the 36in chute) Spring: Homemade see link for directions. I used a 1 1/4in PVC Pipehttp://www.instructables.com/id/Make-your-own-springs-in-seconds/ Servo: 3.7g Turnigy servo (TGY-1370A) Activation: I have my controller set up with two switches to activate parachute. Both switches need to be turned on. This prevents accidental deployment.
