Mi-2 Rotor Balancing

Like the Mi-24 balancing act shown in a previous post,

the Cold War Air Museum, Mi-2 got its turn with the electronic balancing machine. As the blade tracking is adjusted to perfection (or as near as possible), the plane view of the rotor disk (as seen from the side) tends to get smaller or disapper completly. Johnny studies the readouts from the sensors attached to the tailboom.

Before the run, the sensors were attached to the tail.

Other runs were made with other sensor placements. Here sensors are being placed by the transmission while the usual crew of "supervisors" discusses the operation.

After each run, the pilots, techs and mechs talk things over.

  3. The reason I and most heli pilots who advocate safety recomend this is simple.
    When a pilot uses the Thro hold as a method to shut down the motor while working on a heli, they become complacent after some time. Inevitably they begin to rush of forget, and take it for granted the motor is shut down and this opens a door for a terrible accident. Working on a heli at such a close range, it is always best to aire on the side of safety! 
    The Throttle hold is to prevent damage to your gears should you find yourself going down durring flight, most newcomers will do what comes natural and as they panic, the first thing they do is slam the collective down .
