It is necessary to electronically limit the maximum thrust in order not to overpass the maximum RPM for these propellers, otherwise, they can go into supersonic tangential speed. So it was necessary to measure the RPM with a digital laser tachometer and relate the measurements to the imposed thrust.

Thorough Engineering. Sounds like rocket science. Well done.
