The Great Planes Laser Incidence Meter works great for accurately measuring the
pitch of the rotor blades.
1. Attach the meter to one of the main blades close to the rotor head. Position the grips
so they are centered on the bar. This way the weight of the meter won’t try to twist the
blade resulting in inaccurate readings.
2. Using two sticks of wood and rubber bands, construct a flybar clamp that will hold
the flybar level without moving. Typically the clamp is positioned between the flybar
and tail boom.
3. Turn on your radio system and position the throttle/collective stick to the point you
want 0° pitch.
4. Calibrate the meter to 0°.
5. Slowly move the throttle/collective stick and adjust your linkages and radio to
achieve the desired specifications of your machine.
