20	20	The Multirotor Erector Set (MES) - Reconfigurable Frame is an all-in-one frame designed to allow the user to easily experiment with a variety of different multirotor designs, without having to invest in a variety of custom frames. The frame is based on the M.E.S. system which uses aluminum tubing clamps, G10 composite plates and carbon fiber tubing. A wide variety of different designs can be created using this single frame system and each can vary in terms of arm length, motor configurations, accessories and more.

110	110	The types of accessories to connect to the frame are at the discretion of the designer. Components can be added above the frame or below, and a universal mounting plate is included. The length of the landing gear was selected in order to accommodate both a battery below the center frame as well as a standard two axis gimbal. For three axis gimbals, note that the distance between the bottom of the center frame and the ground is ~_~_~_~_.

112	112	The Lynxmotion Servo Erector Set (SES) pattern has been incorporated into several positions on the frame. This pattern allows SES compatible hardware (brackets, C-channels and accessories) to be connected to the frame and used as universal mounting points. When mounting accessories, be check the center of gravity of the entire assembly and ensure it is at the very center of the drone. Should there be a weight imbalance, certain motors may need more power than others, and the flight characteristics may change significantly.

116	116	The MES frame supports using either one centrally mounted battery (below or above the main frame) or two batteries mounted on either the landing gear tubes or above the center plate. In a two battery configuration, we strongly recommend using identical batteries to ensure weight balance and uniform discharge. Note that both batteries should be fully charged before use, and your method of power distribution should support a two battery configuration. The battery is held in place by rubber foam and velcro straps, which supports a wide variety of different sizes. The battery's voltage should ideally match that of the BLDC motors selected, and the continuous discharge current rating ('C' rating) should be above the sum of the maximum current consumption of the motors used.
