    Actually, you guys are right. The BD-4 guys have been using a vane at the corners of the windshield to steer the flow for years. I thought I'd just lay up some fiberglass over a piece of large PVC pipe and then cut them out. The covering on Zulu Delta's pod is junk anyway so a couple of holes for standoffs and a little RTV to seal them back up and we're there. I'm also trimming back all the doors and windows to try and kill those little turbulence makers, too. The wind is blowing so hard here I don't want to fly anyway, might as well build something.

    Chris, The third video showing your house location got me to wondering. Do you have access to the open water via the creek without having to go under a low bridge? If so, have you ever considered floats for you Xtra? -------- Thom Riddle Buffalo, NY Kolb Slingshot SS-021 Jabiru 2200A #1574 Tennessee Prop 64x31 The world is round; it has no point. - Adrienne E.

    Same field as my last post, but recently mowed. The bumpy ground tries to launch me before I am up to speed but I just bump along until I have enough speed and then take off.

    Subject: Re: Tuft video
    From: "Richard Pike" <richard@bcchapel.org>
    Thanks for the tuft video, very informative. Here's a question: I wonder if the shock wave that apparently precedes the prop may have some effect on what the tufts are doing. If memory serves me right you have a 582 so the prop on the side of the fuselage that the camera is filming would be moving from the bottom around towards the wing underside. Standing at the tail, a clockwise rotation. I suppose very unlikely up towards the doors, but perhaps it could affect at least some of the tufting?
