I have no experience with your "bowing" problem. Do have a question for you about "Oil Canning" of the Rudder Skin and did you have the same problem ?? It occurs ONLY on the "right side" of the Rudder Skin: If I press down on the Rudder Skin between Stiffener 1 and 2, it stays DOWN and between Stiffener 2 and 3 the Skin pops UP and stays popped UP. Pressing down between Stiffener 2 and 3 (Skin stays down) and the Skin between Stiffener 1 and 2 pops up and stays that way. Acts like the Skin is stretched. Was VERY carefull with the Skin so as not to damage it during construction. Not sure if this will effect flight characteristics or is a common problem with other builders or can be a future fatigue problem. Anybody have any experience or ideas or knowledge about this ????? Thanks, Garey Wittich Santa Monica, CA ________________________________ Message 2 _____________________________________ Time: 07:00:49 PM PST US From: Matt Dralle Subject: RV8-List: Re: RV-List: Elevator Skin "bowing" and Rudder "Oil Canning" At 11:52 AM 8/25/2008 Monday, Garey Wittich wrote: >--> RV-List message posted by: Garey Wittich > >Matt: > >Thank you for your Matronic Web Site - GREAT help !!! > >I have no experience with your "bowing" problem. > >Do have a question for you about "Oil Canning" of the Rudder Skin and did you have the same problem ?? > >It occurs ONLY on the "right side" of the Rudder Skin: If I press down on the Rudder Skin between Stiffener 1 and 2, it stays DOWN and between Stiffener 2 and 3 the Skin pops UP and stays popped UP.
