Step 2: Calculate the overlapping ranges for the Compensation Curve
adjustment points.
Please refer to the above diagram for the overlapping ranges chosen for the
compensation curve adjustment points. These ranges were defined by Mike Shellim for
his ‘Crow-aware adaptive elevator trim’ developed for OpenTX (see rc-soar.com) and are
used with his kind permission.
I have made a small modification to extend the Pt2 range all the way up to +100% for
reasons explained further down.
As the flap stick is deployed, from +100% downwards, curve point 2 is the first one to be
active and adjustable. Then when the flap stick is between +45% and 20%, both points 2
and 3 will be adjusted simultaneously. When the flap stick is between +20% and -20%,
only point 3 will be adjusted. Then when the flap stick is between -20% and -45%, both
points 3 and 4 will be adjusted simultaneously. When the flap stick is between -45% and
-90%, only point 4 will be adjusted. Finally, when the flap stick is between -90% and -
100%, only point 5 will be adjusted.
Step 3: Configure logic switches for the comp curve adjustment points
For each of the four adjustable curve points, we need to set up a Logical Switch that will
be active when the flap stick is within its defined range.
