Exploration ·
From magnets and coils to a quadcopter in the air: how a brushless motor is wound, how an ESC switches it in six steps, how it finds the rotor without sensors, what field-oriented control does better, and what happens when you bolt four of them to a frame — with the simulators running alongside.
Tool ·
Plan a quad build (all-up weight, thrust-to-weight, hover throttle, flight time, prop clearance), compare and convert Betaflight rates and test them with your transmitter, diff two Betaflight CLI dumps into a script, and open a blackbox log to plot gyro, PIDs and motors with a noise spectrum.
Tool ·
Work out what a motor, propeller and LiPo will do together — RPM, current, voltage sag, power, efficiency, static thrust, pitch speed, thrust-to-weight, hover or cruise throttle and flight time — with warnings for the motor, ESC and battery, a throttle sweep chart and up to three setups side by side.
