The length of the 142 142 143 -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. 144 - 145 145 === Battery === 146 146 147 147 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. ... ... @@ -165,13 +165,7 @@ 165 165 166 166 Should you wish to experiment with a wide variety of different configurations using a single type of motor, ESC and propeller, the following specs are suggested.

Many flight controllers require a full PWM range of 0.5ms to 2.5ms, which often requires that the remote control be configurable / programmable. 176 - 177 -
