Quadcopter

Based on the popular Spyda 500, this variation changes a few things:

• Improved arm design that features a taller landing profile with side reinforcements.
• Relief around bolt holes for washers.
• Plate with holes for mounting a KK2.1 board.
• Corner brackets and mounting hole locations for the QBrain ESC.
• End brackets and mounting holes for a FrSky receiver.
