1) What are the colors on the main rotor blades and hub, the dots that are red, white, blue...
2) What is 2per rev, 4 per rev.....
3) Can a Governor failure (low side) lead to a Bell 412 crash?
4) During Uncontrolled yaw and descent at low Rotor RPM, can the mast bump, or can the main rotor hit the tail boom ??

1.- RED-BLUE and GREEN-ORANGE
2.- Vibs associated with a frequency equivalent to 2 per rev of main rotor, 4 per rev of main rotor, etc...
3.- Sure
4.- Dont know for sure but my logic says yes to both questions
