• If the nose of the helicopter is drifting to the right in hover, you will want to increase the power to the
left-hand motor (spinning the lower main rotor blade). This is accomplished by turning the “proportional”
trimmer pot counterclockwise. (–)
Note: You must always power down the 4-in-1 unit before making adjustments to the proportional
mix trimmer pot. Any changes made to the trimmer pot will not take effect until the 4-in-1 unit is re-
initialized and re-armed.
Also, you should always center the rudder trim lever on the transmitter after making adjustments to the
proportional mix trimmer pot on the 4-in-1 unit.
Note: Be sure to use the proper size and type of screwdriver to carefully make adjustments to the trimmer pot.
Use of the improper size and type of screwdriver or too much force can damage the trimmer pot. Also be sure
to take your time when making adjustments to the proportional trimmer pot as it may only require very slight
adjustment to achieve the desired level of performance.
As the battery output voltage decreases throughout the flight, it may be necessary to make small adjustments to
the rudder trim or rudder control input in order to keep the nose of the helicopter straight. These small adjustments
can be made using the rudder trim lever or rudder control stick and do not require additional adjustments of the
proportional trimmer pot.
