Hover Budget Explorer
Turn the knobs of the EL01 worked-example drone and watch the design loop close: the mass budget sets the thrust needed, the thrust sets the power, and the battery that pays for it adds mass. Numbers come from the same AIR2216 II thrust table and design file as the companion code's hardware engine. Predict before you drag.
The balance: thrust you use, thrust you keep
Each orange arrow is one side's maximum thrust. The solid part is what a hover spends; the pale part is the headroom for climbing, turning, and gusts. The dark arrow is the weight. SYS-001 asks for T/W ≥ 2: at most half of every arrow solid.
