Motor tests

All motor tests are done with a Turnigy MultiStar BLheli_32 51A ESC, with the 32.7 BLheli firmware. ESC config is available in our repository. Current and voltage measurements are done by the ESC and thrust is measured with a 5 kg load cell, coupled with a HX711 amplifier. Tests are done with fully charged lithium batteries, as we do not have a powerful enough adjustable power supply. Tables starts at 50% throttle and continue to 100% throttle in 10% increments.
