My Posts This: Topic Forum | The two knobs do not directly adjust RPM. The RPM changes due to the changes in the Pitch made by the knobs, relative to throttle (which is not adjustable in relation to the stick position).
PLT determines the extreme limits of the pitch (i.e. how much overall pitch travel there is).
PZT displaces the entire curve (if you started out with -10 to +10, then increased the PZT, you might be at -9 to +11. Same amount of pitch travel (as determined by the PLT knob), but displaced, relative to the stick position (and therfor the throttle position).
The tail will settle down more at lower RPM. You can try moving the PZT a bit towards positve, and see if the wagging slows down. Once you get the wagging under control, punch the throttle and make sure that the motor does not bog. If if does, tweak the PLT towards negative and go through the process again.
Run the heat sink on both the main and tail motors, and check the main motor to make sure it is not running hot (too much pitch in the hover, too low an RPM, and it will begin to get how-which you do not want).
