Video transmission: power, antennas and control
Analog and digital systems use different cameras, transmitters, goggles and control protocols. Check compatibility, voltage, dimensions and cooling for the exact components. Matching connectors do not prove compatibility.
Guide notes
Identify the video system
Analog and digital systems use different cameras, transmitters, goggles and control protocols. Check compatibility, voltage, dimensions and cooling for the exact components. Matching connectors do not prove compatibility.
Wire and power safely
Follow the specific pinout for power, ground and SmartAudio, Tramp or MSP control. Connect the correct antenna before powering the transmitter. Verify BEC capacity and protect wires from propellers.
Configure and check
For analog video, match the VTX table, band, channel and goggles. For digital systems, follow the manufacturer's binding and MSP/OSD instructions. Respect local frequency and power requirements.
Diagnose missing video
Remove propellers and power briefly. Check supply, connectors, camera and antenna before channel or binding settings and control protocols. Provide required bench cooling and disconnect if abnormal heating occurs.

Frame: dimensions, screws and wiring
Check supported propeller size, FC mounting pattern, camera width, motor mounting, internal height and battery mounting. Digital video systems also need sufficient transmitter space, cable clearance and cooling.

Brushless motors: selection and propeller-free testing
Stator dimensions, KV, shaft diameter, mounting pattern and supply recommendations are separate specifications. KV describes unloaded speed per volt, not thrust. Use the manufacturer's battery and propeller recommendations.

Propellers: direction, fit and replacement
Propeller diameter, pitch, blade count, centre bore and mounting method must match the motors and frame. A different propeller changes load and handling. Start with manufacturer recommendations.
