What you'll build
Build a tethered lift arm and control its thrust with a throttle knob.
Before you start
You'll learn: How lift, thrust and motor speed work together — and how code controls a motor's power.
You'll finish: A tethered lift model: a motor and propeller that you throttle up and down with code.
Real world: Delivery drones, crop-spraying drones and rescue helicopters all balance lift against weight like this.
Then try: Measure how much weight your model can lift, or code a gentle take-off and landing ramp.
Who does this: Drone pilot or aerospace technician — a drone pilot licence (RPL), TVET, or aeronautical engineering.
