Swash plate function rate settings (SWASH AFR) reduce/increase/reverse the rate (travel) of the aileron,
elevator (except H-2) and collective pitch functions, adjusting or reversing the motion of all servos involved
in that function, only when using that function. Since these types utilize multiple servos together to create the
controls, simply adjusting a servo's REVERSE or END POINT would not properly correct the travel of any
one control. Since H-1 uses one servo for each function, there is no need for AFR in H-1.
Since aileron always uses no more than 2 servos, check it first. Either both operate properly (no change
needed), both operate backwards (reverse the whole function), or one servo operates backwards (reverse that
servo alone). Next check elevator. Remember, the aileron servo(s) operate correctly, so if elevator does not,
we should only have 2 choices left—the whole function needs to be reversed, or the servo(s) not shared with
aileron need to be reversed. If aileron and elevator are not working properly, the only thing that could be
wrong is the whole direction collective operates (reverse the whole function). In our example, HR3 is 180
degrees off from the swash plate of the Caliber. Therefore, it is very likely that several functions will not
operate properly. The collective pitch operation is backwards; but reversing all three servos would also
reverse the aileron and elevator operations. Changing the collective pitch rate, however, from +50% to -50%,
will reverse the collective pitch without affecting the aileron action.

5.3.1 THR-CURVE and PIT-CURVE:
These 7-point curves are utilized to best match the blade collective pitch to the engine RPM for consistent
load on the engine. Curves are separately adjustable for normal, idle-up 1, idle-up 2, and idle-up 3. In
addition, a separate collective pitch curve is available for throttle hold. Sample curves are displayed in the
appropriate setup types (ex: normal flight condition) for clarity.
