Older Venti have an innovative ground-breaking (read damn-
peculiar and given up on later models) drive system for the
flaperons, using a cam-follower. Now, the track that the cam
rides in is lined with teflon. Unfortunate lubrication of said track
attracts every bit of dust and fiber-grinding-debris in the wing and
results in stiff control operation and abrasion of the teflon track.

Don't go blasting lubrication in there...

Hope this helps,

Just so no one get confused, the "older Ventii" refers to the Ventus A
and B models with the trailing edge dive brake/flap combination. The
Ventus C with full span flapperons and SH dive brakes did not use this
troublesome drive arrangement.
