thingiverse

These attachments are specifically made for use with the DJI F450 F550 Flamewheel Long Leg Extensions - 5mm Thick on Thingaverse. They enable secure attachment of your quadcopter to an engine "runup" pad during testing or maintenance, preventing unwanted takeoffs and ceiling damage. Print four of these, attach them to a heavy object, and insert nails for connection to the runup pad; enjoy safe, ding-free testing. The design is available in Sketchup format for customization.
