Tail Rotor Proportional Mix Trimmer Pot Description and Adjustment
After establishing a stable hover, you will first want to adjust the tail rotor proportional mixing. The “proportional”
trimmer pot adjusts the amount of tail motor to main motor mixing.
In hover, with the rudder trim centered and no rudder input, note which direction the nose of the helicopter is
trying to spin. If the nose of the helicopter is spinning to the left, you will want to increase the amount of tail motor
to main motor mixing. By turning the “proportional” trimmer pot clockwise (+), you increase the tail motor/rotor
rpm for a given main motor/rotor rpm. This increase in tail motor/rotor rpm will help to push the nose of the
helicopter to the right when in hover.
If the nose of the helicopter is trying to spin to the right in hover, decrease the tail rotor proportional mix by
turning the “proportional” trimmer pot counterclockwise (-).
Note
: You must always power down the helicopter before making adjustments to the proportional mix trimmer pot.
Any changes made to this trimmer pot will not take effect until the 4-in-1 unit is initialized and re-armed.
As the battery output voltage decreases throughout the flight, it may be necessary to make small trim
adjustments to the rudder in order to keep the nose of the helicopter straight. More experienced pilots may
also choose to adjust the proportional mix to better hold the tail during aggressive climb outs and aerobatics
rather than in hover only.
The amount of tail rotor proportional mix required may vary based on the type and performance of the chosen
flight battery. When switching from 8-cell Ni-MH to 3-cell Li-Po for example, adjustments to the proportional mix
will be required.
