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 ·
For your flying fields: the hourly forecast — wind and gusts at 10 m and the wind at 80 and 120 m, rain, cloud and an estimated cloud base, visibility, temperature — and the geomagnetic Kp index, judged against each aircraft's limits as a go / marginal / no timeline for 48 hours or 7 days, with the reasons, the best windows and the runway crosswind.
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 ·
Keep a register of your LiPo packs — cells, capacity, C rating, chemistry, age, cycles, and internal resistance over time on a chart — with a quick log after each charge or flight, warnings for rising IR, out-of-balance cells, old and puffed packs, calculators for charge current and time, storage voltage, parallel charging and airline watt-hour limits, and QR labels that open a pack's record.
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.
