Had a minor TRCF as a stude. After pulling to a hovering stop on the helipad I turned the H300 around and began a hovering taxy towards the hangar. As I picked up speed and started relaxing the left pedal I got no response, a slight push on the right pedal did nothing, so I tapped the left pedal a few times and normal control resumed for an uneventful landing. Although the problem was a binding cable it didn't seem like a big deal at the time. Reported it to maintenance nonetheless.
TC in your notes would you include something in there about short shaft failure as on some models full T/R performance is still available when it happens. Does anyone know if the engine surges and overspins the T/R before the fuel control eventually compensates for the sudden loss of engine load?
