Quick Answer
Adding FPV to an RC plane means installing a camera and video transmitter so you can see a live feed through goggles. You need an FPV camera, a 5.8GHz video transmitter, matching antennas, and goggles. Most setups can be added to an existing plane without modifying the flight hardware.
What You Need for an FPV Plane Setup
A basic FPV setup has four components: a camera, a video transmitter (VTX), antennas on both the plane and your goggles, and the goggles themselves. The camera mounts in the nose or wing, pointing along the flight path. The VTX sends live video over 5.8GHz to your goggles on the ground.
Power is straightforward. Most FPV gear runs on 5V from a BEC or your flight controller. Avoid powering the VTX from a servo channel, as the noise causes video interference. The total weight of a typical analog setup is around 30 to 50 grammes, manageable for most RC planes. Place the gear near the existing electronics to maintain the aircraft's centre of gravity.
Choosing an FPV Camera for RC Planes
RC planes benefit from cameras with good low-light performance and a wide field of view. Unlike racing quads, planes fly at altitude in changing light. The RunCam Phoenix 2 Nite offers a 1500TVL sensor with strong starlight sensitivity, making it a solid choice for early morning or late afternoon flights.
Look for a field of view between 120 and 150 degrees. Narrower and you lose peripheral vision. Wider and the horizon distorts, which is disorienting on long flights. Mount the camera as far forward as practical, angled 10 to 15 degrees below the horizon so you can see the ground during level flight.
Selecting a Video Transmitter
The VTX determines your video range. For most RC plane pilots, 200 to 600mW covers flights up to 1km with a decent antenna on the goggles. The EMAX Wyvern Link Alpha V2 800mW VTX provides the power for longer range flights over open countryside.
Match VTX power to your environment. At a club field with other pilots, 25mW avoids interference. Flying solo, turn it up. Most modern VTX units support switchable power levels. Always check which 5.8GHz channels are clear before powering on, covered in our FPV frequencies and channels guide.
Antennas and Goggles
Antenna choice has more impact on range than VTX power alone. Use circular polarised antennas (RHCP or LHCP) on both ends. A patch or helical antenna on the goggles pointed at the plane gives significantly more range than an omnidirectional one. For more detail, see our FPV antenna guide.
Analog goggles are the budget-friendly entry point with zero latency. Digital systems like Walksnail or HDZero offer sharper images but cost more. Browse our FPV goggles range to compare options.
Installation Tips
Keep camera and VTX wiring short. Long wires pick up electrical noise from your motor and ESC, which appears as lines in the video. Route FPV wiring away from servo leads, crossing at right angles where necessary. Secure everything with Velcro rather than zip ties, which can vibrate loose. Test the complete system on the ground before the first flight.
FAQ
Q: Can I add FPV to any RC plane?
A: Most planes can carry a 30 to 50g payload. High-wing trainers and larger sport planes are the easiest to convert. Foamies under 300g may struggle with the extra weight.
Q: Does FPV affect the centre of gravity?
A: Yes. Place the camera and VTX near the existing CG point, roughly a third of the wing chord back from the leading edge. Add a counterweight if needed.
Q: Do I need a licence for FPV RC planes in the UK?
A: You need an Operator ID from the CAA for any aircraft with a camera. When flying with goggles, you also need a spotter maintaining direct visual contact at all times.
Q: What range can I expect?
A: A 200mW VTX with decent antennas gives 500m to 1km of clear video. Upgrading to 600mW or using a directional ground antenna pushes this to 2km in open terrain.
