The APEX 3inch drone frames have a designated size class, based upon the longest distance from motor to motor measured in millimeters, typically taken by measuring diagonally across the frame. A-frame measuring less than 150mm motor-to-motor is categorized as a micro. A-frame larger than 150mm motor-to-motor is considered a mini

In summary, carbon fiber composites offer great benefits in drone making. Its malleability allows machining carbon fiber sheets into various shapes relatively easy. The high percentage of carbon atoms in it gives it the advantage of high tensile strength, high stiffness, and low weight
