Drone Weight & Frame Size Calculator
EveryDroneFind minimum frame size to avoid prop strike, and check disk loading
Weight & Frame Size Calculator
Assumptions
- Motors arranged in regular polygon (equal spacing)
- Frame diagonal = motor-to-motor distance
- Disk loading: Low (<50) = efficient, High (>100) = review needed
When This Estimate Breaks Down
- H-frame or stretched-X layouts need custom calculation
- High disk loading may cause efficiency loss and noise
- Frame class matching is for reference only
