AR Drone 2.0 Upgrade Tool Kit AR Drone 2.0 Upgrade Tool Kit. The magnet tips are extra strong, it includes every piece in the yellow kit and lots more, including a better c-clip tool and two flat-heads ideal for working with the tiny connectors on the interior, and removing bushings and bearings takes about 5 seconds--no more fiddling around with shafts. Extra bits not included in the standard yellow kit: one prying bit perfect for gently removing stickers and the bottom plate of your drone; a poking bit, helpful when inserting zip ties into the styrofoam body. One PH3 bit, useful for removing motors, making it simple to push the motor out by pressing on the pinion gear--the motor will slide out easily through the foot. And a simple flat-head is perfect for removing the connectors from the motors and mainboard so you don't break your fingernails or worse yet damage your drone's internal parts. There are several more useful bits--the blue kit includes all the tools in the yellow kit, plus extras for your drone, with stronger magnet tips.
