Just wanted to know if anyone has experienced a mild pulsing type vibration when pushing during a slow roll? Been doing them for years and just noticed it on the last flight. Same speeds and G's as usual. Not evident under positive G. Won't have time for a few days to start pulling panels, but nothing unusual noted on post flight. Thanks
