This is consistent with s= ome limited VG experiments Len made on my airplane.
In other words=2C y= ou still have limited to no aileron authority at the stall.
Len d= id do some experiments that resulted better characteristics at the stall bu= t higher stall speed.
An interesting question is "Would you rathe= r have more control at a higher stall speed or less control at a lower stal= l speed?"
