While browsing the RAH newsgroup, I saw an interesting posting of a
roll-trim concept being used on canard. Designed by Mr. Wright and Mr.
Hanka, it utilizes a composite spring in the shape of a circlip, with
one end attached to the aileron drive and the other to a servo. As with
the bungee idea, there is no need to modify the aileron, but as with the
embedded aileron servo, it is still infinitely adjustable with a switch.
I found the idea a good compromise, and a keeper. I wonder if there is
room in the spar tunnel to hide the servo and spring instead of crowding
the footwell?
I've attached the jpeg of their design for John to put up on the support
site if he so wishes. The original post to RAH claimed no intellectual
rights, so posting shouldn't be a problem (the design is quite basic in
any case).
Cheers,
Pete
