Workflow
Calculate Link Budget
45 minutesCompute link budget from TX power, antenna gain, receiver sensitivity, and expected range.
Assemble and Wire LR Gear
2-4 hoursInstall VTX, mount directional receiver antenna, wire GPS rescue, and configure failsafe RTH.
Test Flight and Range
1 hourFly incremental range tests with spotter, verify RSSI at distance, and test GPS rescue trigger.
Tools Used
- FPV Range CalculatorPrimary
Estimate achievable range from VTX power and antenna configuration.
- Antenna Length (Dipole / Quarter-Wave)Primary
Cut receiver and VTX antennas to correct quarter-wave length.
- Link Budget CalculatorSupporting
Verify link margin at target range with terrain and obstacle losses.
- Drone Flight Time and Discharge Telemetry CalculatorReference
Ensure battery capacity supports outbound range plus return flight.

VLOS RuleStandard
FAA requires visual line of sight — spotter required for LR.
Spotter Required
Long-range FPV exceeds visual line of sight — a dedicated spotter is legally and practically required.
GPS Rescue First
Test GPS return-to-home at low altitude over open field before relying on it at distance.
900 MHz Antennas
DIY quarter-wave ground plane antennas cost $5 and outperform many commercial options at 900 MHz.
Safety Notes
- Long-range flight requires visual line of sight via spotter — flying beyond VLOS violates FAA regulations.
- Configure GPS rescue failsafe and test it before every long-range flight.
