Rotor Nut,
On a little flight into Leeds from Egnh, whilst passing over the outskirts of Keighly leading into Baildon two of us each in a R22 I was acting as radio man and leading when something happened to both my radio and at the same time the compass went walkabout and left me guessing for the direction( not good viz) after about 2 mins everything was back to normal but left me feeling a little twitchy flying into Leeds airspace. Tech chaps did not know why and could not find anything wrong with the equipment on the R22, I also have heard the clutch on the Rad.
