I've since found some thinner stuff from = Aircraft Spruce that will allow the 18 bid and be within the plan spec, I = think. B.T.W. have you noticed any bowing in the middle when closing the = canopy? Any recommendations for the strip stiffener in there? Thanks Doug >>> Larry Henney 02/23/09 5:01 AM >>> Doug, I went with the 18 Bid per the plans on 3 aircraft. =20 If you are referring to the leading edge contact at the header tank thickness..?.... All 3 that I built required trimming the carbon back the width of the header tank overlap (or about 3/4"). No problems on mine 850 hrs to date. No cracking. Am I missing your question. Why would resultant calculated thickness have anything to do with plans requirement of bids?=20 Larry Henney=20 -----Original Message----- From: Doug Baleshta [mailto:dbaleshta@tru.ca]=20 Sent: Friday, February 20, 2009 12:51 PM To: lml@lancaironline.net Subject: forward hinge canopy bid thickness LN360 Hi folks, the forward hinge canopy calls for up to 18 bid of unidirectional= carbon fiber. I measured the thickness and according to the plans it = should be around .140". The only unidirectional fiber I've found measures in at .023, or about 7 bid. Has anyone else come across this and what did you = do? Did any of you use bi-directional CF with any problems?
