Nizar is right, those drone motors are 3 phase permanent magnet, brushless
DC motors with PWM controllers which are very noisy. This would require
sophisticated noise canceling software as well as hardware mitigation.

Make sure the Drone electronics is quiet enough to not interfere with the

Considering you can buy a small drone with a camera for less than $100, an
amateur FSD could cost less than $200.

OK, what is an FSD? It is a Field Strength Drone. It’s an idea I am sure
others have had, and I don’t expect to get around to designing or patenting
such a thing. But inventions are often just the merging of new
technologies, and this is not much different. I don’t see any YouTubes
about this or any other reference, so here’s the idea:
With all the capabilities of little drones I wonder if anyone has designed
one which can carry a field strength meter and fly a grid around an antenna
to evaluate antenna performance. The guts of my little Radio Shack FSM
would have weighed way less than an ounce.
Ideally, the field strength meter could communicate to the base through the
drone transmitter, reducing weight. Software at the base could link the
drone 3D location data with the FS reading. The drone would have to wait at
test locations for the operator to transmit, and ideally would move to the
next location. Finally, the software might be able to link with existing
simulation software for comparison with theory and allow for simulation
model improvement. This looks like it would take a small team to develop.
This sounds like it would have many uses besides antenna evaluation, like
RFI evaluation.
What about it? Has anyone done this?
