Bicycle Bob:

I'm planning to hinge mine at the top, as you suggest and as basjoos did on his Civic: http://ecomodder.com/forum/showthrea....html#post2112

Though once I start construction, I'll probably wish I'd followed the "rubber membrane" method Newton used on his Mira: http://ecomodder.com/forum/showthrea...kirts-398.html

I also like your idea of servos for hinge control (hadn't thought that there might be feedback if there were a direct link to the steering bits).

But I'm going to keep it simple and go with a low friction plastic stuck on the back side of the skirt which the tires will contact when they are steered. basjoos went with low profile metal rollers.

For chuckles, some pics of the camera rig, or more technically, "web cam on a metal stick, secured with duct tape, a nylon strap, rope and a bungee":



The boom is an extruded aluminum U-shaped member (the track from a large vertical blind), secured to a roof rack. Between the "skirt off" and "skirt on" video sessions, I added the rope that goes from near the end of the boom to the bottom of the passenger door, tensioned with a bungee cord to the rear of the car. That put some pre-tension on the boom and reduced the camera bounce/wiggle compared to the runs without it.





It stuck out about 4 feet from the side of the car.

I was careful not to overtake cyclists or drive close to sidewalks or utility poles!
