Has anyone every experienced a situation where there is a consistent " surging " or fluctuation of the engine caused by governor. I recently visited a Helicycle owner to purchase a Helicycle and at idle there was a constant fluctuation of the engine RPM verus smooth and steady running . It did appear to go away during a flight he made but was again noticeable afterwards. You could see the governor control arm moving in almost a rythmic cycle causing variations of RPM of 5-10%. (example : at 80% you would get fluctuations above and below by 5-10%. You could hear the turbine reacting to the changes. There were no inputs being made .
This may not be explained well but has anyone noticed this before?
