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 Features: High tensile strength High stiffness Light weight Made of carbon fiber Easy to assemble high durablity Long life Specifications: Brand Name: Readytosky Material: Carbon Fiber Recommend Age: 7-12y Recommend Age: 12 y Recommend Age: 18 Tool Supplies: Cutting Upgrade Parts/Accessories: Frame RC Parts & Accs: Carbon Fiber Quadcopter Frame Size: 150mm 190mm Use: Vehicles & Remote Control Toys Quantity: 1 pcs Technical parameters: Value 6 Model Number: APEX5 APEX 3 inch / 4 inch Remote Control Peripherals/Devices: Remote Controller For Vehicle Type: Airplanes Four-wheel Drive Attributes: Assemblage Parameters: Name: HSKRC-APEX-3inch/4inch Propeller: 3 inch / 4 inch Wheelbase: 150mm / 195mm Arms plate: 4.0MM Top plate: 1.5MM Bottom plate: 2.0MM Side plate: 1.5MM Recommended configuration: ( Not included) Flight Controller size: 20 x 20mm Motors: 1406 /1507 ESC: 20A-30A Propeller: 3 inch / 4 inch Battery: 4S 850mAh-6s 850mAh Packages Includes: 1 x APEX 3inch 150mm Carbon Fiber Frame Kit Category: Drone Kit Tags: APEX, Carbon Fiber Frame Kit
