Hi Tim. You may want to redo you throttle setup to eliminate the differential
you've created. Ideally, the normal throttle curve should be linear from fully
closed to fully open, with hover throttle at about 45% open. This is
regardless of the engine, fuel, muffler, etc. being used. Additionally, the
linkage should be at 90 degrees to the throttle arm AND servo arm at hover.
Adjust only the pitch curve to achieve the desired RPM's. That way, the engine
can "keep up" with the load. The way I've interpretted your current setup, the
throttle is lagging too far behind the pitch curve, and your engine will bog
under the increasing load as you open it up.
