Carbon Aeronautics quadcopter

What the base build uses

Project 1 lists a Teensy 4.0, a GY-521 MPU-6050 orientation sensor, a GY-BMP280 barometer, four GEPRC GR1105 5000 kV motors with HobbyKing 6A ESCs, Gemfan 3018 propellers, a Turnigy 2S 1300 mAh battery with a HobbyKing B3AC charger, and a Flysky FS-i6 transmitter with an FS-iA6B receiver. The lower and upper frames are Carbon Aeronautics parts. The manual gives the basic build's weight as 247 g. It reports tested alternatives, including 1000 or 1500 mAh 2S batteries and a GR1206 4500 kV motor with a 12A ESC, and says the heaviest combination weighs 278 g. Propellers are limited to 10.2 cm diameter. Required tools include a soldering iron, wire stripper and cutter, 1.5 and 2 mm hex keys, a multimeter and a computer that runs the Arduino software with the Teensyduino add-on. [S004]

The upper frame is a printed circuit board that carries the control electronics, power distribution and most of the wiring. The Part 0 README says the frame PCB was designed in EasyEDA and links it on OSHWLab. Those design files were not preserved or inspected for this profile, so their completeness and license are unknown. [S005] [S006]

Claims to read carefully

The cover lists a 10-minute flight time. In the simulation chapter that figure is calculated from hover current with a 1300 mAh battery and described as an upper limit, with real flights expected to be shorter. The worked numbers also shift from 7.4 A to 7.8 A within the calculation. Treat it as an estimate, not a measured endurance. [S003] [S005]

The safety page tells builders never to charge batteries unattended and to check their country's rules on altitude, speed and weight before flying outdoors. Its motor guidance needs care: one line says to remove the propellers until the program is known to work, and the next says never to run motors without propellers. The page does not reconcile the two, so the intended test sequence should be confirmed in the relevant project chapter or with the author. The manual makes the user responsible for complying with local unmanned-aircraft regulations. [S003] [S004]

Rights, cost and gaps

The manual's text and figures are licensed CC BY-NC-SA 4.0, and the headers of the Part XVI angle-mode and Part XX vertical-velocity code apply the same terms. That permits noncommercial adaptation with attribution and share-alike. It does not grant commercial-use rights, and no separate license file was identified in the repositories. GitHub reported no license for the manual repository. [S002] [S003] [S007] [S008]

No upstream price, BOM total or kit price was identified, so no budget is given. No assembly, flashing or flight was performed for this profile. [S004]
