A capacitor across the battery leads is one of the cheapest, highest-impact additions to any FPV build. It suppresses voltage spikes, cleans video feed noise, and protects ESC MOSFETs from back-EMF transients. Why Voltage Spikes Happen When a motor changes speed rapidly, it generates back-EMF — a voltage spike that …

Map a transmitter lever, wheel, or switch to cycle through VTX power levels in Betaflight. Useful for pit mode on startup, low power for close proximity flying, and full power for long range. How It Works Betaflight reads an AUX channel and maps PWM ranges to VTX power table indices. The VTX must be connected to the FC …

Reduce CPU/GPU voltage to lower temperatures and power consumption while maintaining performance. Why Undervolt? Benefits: Lower temperatures (5-15°C reduction) Reduced power consumption (10-30W savings) Quieter fans Extended battery life Same or better performance (less thermal throttling) Risks: System instability if …
