Jeff, Wow do those lights make it happen at night! That is some real flying skill there! Isn't that recovery a rush!! Excellent job with this. That vibration gets a bit more of a problem the higher you go and that has been my experience also - exactly. We'll get that down a bit as we go along. I take the flyer down in an arc across the sky now to avoid that prop downwash. No snow where you are but we are still covered here.
