Very good report, Bill

The Nimbus 3 and the Genesis 2 have very small *tip spoilers*, in addition
to
normal differential ailerons. They seem to work by add a bit of drag, way
out
near the tip and help counter the adverse yaw. They are about 4" X 18" and
move
up twice as fast as the aileron, so that full aileron gives a spoiler
standing
up at 90 degrees. The early Genesis 2 had these tip spoilers actuated by
the
rudder pedals, but later models used the stick to actuate them. The return
spring used on the tip spoilars gives just enough input to keep the stick
centered. I like that because I know the stick is perfectly centered, by
just
relaxing my grip, a tad.

I was told that the original system on the Genesis was much superior to the
final version but that the "production costs" were higher given the long
control cable routing and the need to deal with differential thermal
expansion effects on the control system. I didn't quite buy the argument.

That said, the later Genesis that I flew handled pretty well.
