Not sure if this belongs here or in the RV-12 section . . . .
Flew an S-LSA RV-12 the other day and there was a short yet pronounced vibration that even seemed to affect the arc of the prop spinner (appeared to be ecentric during the life of the vibration).
The owner told me the vibration was short lived and consistently occurred about 250' AGL on takeoff.
We were able to determine that the vibration occurred as the nose wheel spun down to "0" RPM.
This was determined by doing a touch and go while keeping the nose wheel off the pavement - no vibration whatsoever.
Any one else experience this?
Any thoughts or recommendations as to a cure?
