Another vote for being able to feel wake turbulence when doing 60 degree turns without losing height.
I have looked but not managed to find figures for how fast light aircraft wake vortices descend. I did find a suggestion that it was slower than a vortex from transport-sized aircraft. Or perhaps it's related to wing loading... same result. I'm afraid I've lost the link.
Do vortices initially descend? For example, if you were at the top of a loop, wouldn't your vortices actually go up? If so, then when doing a 60 degree turn your wing vortices will initially be cast off more laterally than downwards, and perhaps your outboard vortice will actually rise or stay level (in the pictures they always seem to diverge laterally outwards).
