Tank Slappers

[rev 01]

I took off over a hump @ warp speed & came down with the front crossed up due to a crosswind & the old bus shook it's head once & kept on trucking Gyroscopic force tends to keep things (wheels) in line.

There is a video I saw where a bloke deliberately induced a slapper by shoving the bars & then letting them go ..........straightened itself every time <i></i>
