It's like many people with FWD vehicles, if they need to use it, they don't know how, or didn't even know they had it. ( thought FWD was just something that sounded impressive ).

" Rudder " however doesn't sound at all impressive - not like FWD.

Maybe it would be useful if the ailerons failed, don't throw it away!

Wouldn't like to take off my taildragger without a rudder!
