(Jeremy Davey) ________________________________ Message 1 _____________________________________ Time: 01:35:47 AM PST US From: freefolk@screaming.net Subject: Europa-List: Gurney Flaps --> Europa-List message posted by: freefolk@screaming.net 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?

To show my own level of ignorance what is a Gurney flap ? if fancy I should know but!!

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.
