On the return to Gloucester today ATC gave winds of 220/12kts , I taxied back to the hanger and stopped to turn to fly down taxi way Hotel roughly 090 when I ran out of left pedal pulling 23inches manifold pressure ending up facing 160 roughly. I had 1.5 inches manifold pressure spare left to the limit, just a Beta.
I turned back round into wind and waited in the hover for about 30 seconds still IGE and tried again....fine no problem.
Has anyone experienced anything similar?
I think the wind was gusting slightly more than forecast

Hmm, interesting one there PW. Can't say I ever had that happen in 2 years of instructing on 22s'. That was in the NE of Scotland, where we were consistently out in 25-30 kts, so I can only imagine you've had a decent old gust come thru. _________________ Generally wrapped in rubber, be it in the air or on the water.
If you were taxiing towards Bond/Rise/Heliflight, I often get a strong "shimmy" from the wind tunnel created by the buildings around that Taxiway by Heli South, especially Taxiway Hotel. Chances are you got caught in a particularly strong gust around there. I've never ran out of left pedal myself, but it's usually pretty lively on the pedals just at that point.

The R22 has very good tail rotor authority. Frank Robinson was a tail rotor designer for Hughes before he set up Robinson, so thatīs one good thing about the Robbie that came in handy a few times in the stiff scottish breezes.
If you find it too difficult to hover taxi in a cross wind which is getting close to the pedal stops, then simply hover taxi side-ways and slowly. I would rather I saw my students do that then try and fight a loosing battle. Loss of tail rotor effectiveness is not fun. But at the end of the day ask your instructor for advice, and mention some methods you have read. He will be more current on the R22 then I am!
