Betcha you could understand non-linear math
by figuring out the source of flutter in control
surfaces, and then why a mass counter balance
is needed even for a 152.
"Flap flutter." Well, it might be news to you that flaps don't
have mass balances. They're not subject to flutter.

What? "You've never seen flap flutter". You missed the infamous
"Cherokee Dance" created by flap flutter when the ol' Johnson bar was
coupled to a pilot with a case of nerves who kept missing the catch?
Wellll...It is more of a low frequency oscillation rather than
flutter.

Johnson bar fun is when you have a sweaty hand one day in one of the early
Cessna 150's and you thumb the release catch after a short field takeoff
and it slips out of your fingers. The resulting BANG when it hits the
floorboard as the flaps come up in a nano second can give the guy next to
you a heart attack!

I remember a new 1953 Tripacer. We had four folks in it and landed on a
grass strip. After we landed we realized the grass hadn't been mowed for
quite a while. Couldn't get up enough speed to take off. I had a bright
idea. Started the takeoff roll and started pumping the Johnson Bar for the
flaps. The airplane started bouncing and everytime we bounced out of the
grass it accellerated a little bit more. We made it off before we ran out
of runway. I felt like I jacked that darn Tripacer into the air! :-)
