Logically, there may be an effect in reducing the spanwise flow over the outboard section of the (fowler) flap, when the flap is deployed. But drag in that configuration is a definite advantage in getting the a/c on the ground. Might be worth exploring to see if there is any detectable decrease in stall speed?

What say yee gentlemen to that. Or is it a lot of work for no real gain Regards Craig Kit 577, final prep before paint -----Original Message----- From: owner-europa-list-server@matronics.com [mailto:owner-europa-list-server@matronics.com] On Behalf Of zwakie Sent: Saturday, 14 October 2017 7:01 AM Subject: Europa-List: Re: Full trigear speed kit vs hinge fairings only jonathanmilbank wrote: > I particularly like this quote from Bud: "The flap brackets (especially the outers) are a huge drag source. So is the gear. Gear drag is interesting. The legs and brake callipers actually produce more drag than the tyres and wheels."

Perhaps consider thinning out the cushion behind your back by 2 inches. Not much is needed for comfort and you gain 2 inches space and can possibly stretch out one of your feet between both rudder pedals while in cruise Christoph Both #223 Wolfville NS Canada On 2017-10-15, 19:17, "owner-europa-list-server@matronics.com on behalf of craig" wrote: Ok thanks frank Do not archive ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message europa-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/Europa-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/europa-list Browse Digests http://www.matronics.com/digest/europa-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
