I would like to try using a Gurney Flap rather than a conventional trim tab
to take out about one pound of stick force on the ailerons. Does anyone
have suggestions on the size of such a device as a starter and position along
the trailing edge spanwise?

I was advised (by Graham Singleton I think) that before adding tabs etc to
resolve roll trim issues you should look closely at the flap settings in the
up position.
slight asymmetry in the flap settings could easily cause uncommanded roll .
To show my own level of ignorance what is a Gurney flap ? if fancy I should
know but!!

So slit a round pencil lenthwise then experemented the length by bonding
under trailing edge of offending aileron. Problem cured.

In a Europa you would need 2 pencils - one with pax, one without (or
perhaps just one removable one).

Folks,
It=92s that time of year again =96 the PFA EC nominations! They have to be in by
23rd July.
This year we have 2, possibly 3, long-term members of the EC standing down.
We also have a spare place that was not filled last year. So a minimum of 3
new folks are needed, and more are always welcome.
It would be great to get more of a Europa community presence on the EC =96 we
already have Alan Twigg and David Corbett as well as myself =96 so if you
think this is for you, please get your nomination in.
If anyone wants to discuss what EC membership involves, I=92d be happy to
discuss it one-on-one. It=92s certainly an eye-opener, and very rewarding.
Kind regards,
Jeremy
