There is one central location that is not subject to prop blast,

Visualize a small hole set about an inch back from the front.
Use a local pressure sensor chip and a wireless transmitter.

The flow from off axis would module the air pressure slightly
one cycle per revolution, with amplitude in proportion to

The wiring might be a little tricky

A wireless chip to a fixed receiver chip is not a biggie. But getting
that sensor chip and transmitter chip inside the nose cone in dynamic
balance would be an issue, I reckon....
