Fig 2.2. Polar chart - propeller balancing
The chart shows some text in yellow boxes that describes the current point:
The top-left box contains the tacho channel name (A or B) and the current
point's propeller RPM.
The top-right box contains the accelerometer channel name (X, Y, X2 or Y2)
and the current point's IPS and DEG values.
The bottom-right box contains the date & time the current point was measured.
The bottom-left box is only visible if there is a start point defined for the axis.
It shows a “solution”, i.e. what adjustment needs to be made to the balance
weight to improve the balance. The adjustment has the form ANGLE × SCALE.
ANGLE is signed; a positive value means move the weight forward (in the
direction of propeller rotation) that many degrees and a negative value means
move the weight backward (opposite to the direction of propeller rotation).
SCALE is a multiplier that specifies the required change in weight; e.g. a value
of 1.2 means increase the weight by 20%, a value of 0.5 means halve the
