[Land-speed] Aero Surfaces...

[Glen Barrett]

Art Arfons had a movable wing on the Green Monster jet car. Others have 
tried different things over the years but I don't have a record on who tried 
what. It don't take a lot of movement to upset the balance. What works in a 
wind tunnel may not work on the salt. But that's what LSR is all about , 
trying things.
