If you are looking to throw a little drone party, you might be considering having multiple drones flying at the same time. Almost every drone on the market operates in the 2.4 or 5 GHz frequency ranges. That said, they usually differ very slightly within a few channels. On the racing scene, you'll mostly find up to 40 different available video channels, but there may only be about 8 clean control channels. If your chosen drone uses a basic analog connection, then you may see cross-talk with just a few drones connected, more advanced drones can dynamically scan frequencies to find an open channel, higher-end drones will use a digital connection, which is sometimes encrypted, making it very hard to hijack the drone with unauthenticated signals. Bottom line, the exact number of drones you can connect simultaneously differs based on the manufacturer and drones in use, but we expect you can get at least four at the same time without much trouble. Note: You are legally only allowed to fly one drone per pilot. If you were looking to throw a drone light show, you'll need to work closely with the FAA to get all of the requisite waivers for the operation.
