Can I use this on a flying field with other planes using 2.4 GHz systems such as Spektrum or FASST?
Yes you can! However a few precautions should be taken to avoid static/interference on your video feed. When there are 2.4 GHz fliers at your field, situate yourself 30-40 feet away from them. With FPV you don’t need to be right up on the flight line to fly, so this is usually quite possible. When flying FPV, it’s sometimes hard to see to the side of you without physically turning the aircraft, so be respectful of others in your airspace and fly away from them if possible.
