Launch Platform for DJI Phantom 2 vision plus.. Alternative to an 8th channel expense

thingiverse

Ok Guys! VS8 Success! If you own a DJI Phantom and access to a 3D printer, here's your alternative to a $350+ channel that costs less than $20. Launch something from above with VS8, and notice: no changes in flight characteristics despite landing gear or gimbal guard - we're happy to announce 11 consecutive flights without any flight characteristic changes! The only noticeable difference was a reduced flight time of around 17+ minutes. Weights: Landing Gear/Gimbal Guard = 49 gms, Empty Balanced Snap on Launch Platform = 114 gms, Total Weight = 163 gms. Currently working to determine if a long hinge microswitch and fulcrum might be more efficient than a brush system while considering the additional strain on the gimbal system. Also exploring 6V vs 3V power options. Instructions: The STL files are arranged for optimal print configuration based on my printer's capabilities (XYZ). You may find better print orientations depending on your printer's ability to produce near-perfect circles. The basic landing gear and Gimbal protector is a single print that mounts easily with two small cable ties. Super Glue is used to bind the sides to the bottom 'A', bottom 'B' (print 2) to the balance rails of bottom 'A'. Other assemblies involve using conductive tape, file cut paper clips as hinges, and applying a dab of super glue for bonding. We use double-sided tape to attach the 3V battery housing. Hinge material is obtained from a jumbo paper clip; LatchMec T Pusher's contact with Ejector uses this hinge. The motor housing and spindle are designed for a geared motor with a 2.1mm shaft. We made brushes by cutting brass pipe screens, crimping one end to solder, then gluing them to the contact boom. We applied super glue or medium-cure epoxy for attaching brushes and securing wiring. A twine-based cable is used for the motor spindle. When assembling Latch Mec Circuit breaker and battery assemblies, we apply multiple layers of conductive tape to determine the preferred fit. Note the placement of conductive tape at the camera's bottom corner for proper operation, along with rubber band 'routing' guidelines.
