Used for maximum range only — flight time comes from the power model and does not change with speed.Battery Voltage (V): 11.1V
Multiplier relative to hover power. Depends on airframe drag and speed.
Battery Discharge Graph
⚠️ This is a simplified ideal discharge pattern for visualization. Actual voltage varies with C-rate, temperature, and battery age. This graph does not affect flight time calculations.
Assumptions
- Hover-centric estimate (not forward flight optimized)
- Assumes 80% usable battery capacity for safety
- Uses average discharge voltage (3.5V/cell), not nominal 3.7V
- Cruise time uses a multiplier on hover power (adjustable in Standard/Advanced)
When This Estimate Breaks Down
- Actual flight time varies with wind, temperature, and flight style
- High current draw causes voltage sag, reducing usable capacity
- Forward flight efficiency depends heavily on airframe design
