Couldn't find it in the manual anywhere on on the drawing. We torqued them to 20 inch pounds and the arm would barely move with finger pressure. That little flap motor would have to work pretty hard to move the arm along with wind loading in flight. Thanks in advance. - Ken ________________________________ Message 2 _____________________________________ Time: 02:19:31 PM PST US Subject: Re: RV-List: F-445 bolts From: Denis Walsh Whatever the good book says for those size bolts, 20 sounds about right but check. What you need to do is add washer(s) between the blocks as necessary to relieve the pressure to a reasonable amount. Start with a "thin" washer and add as neccesary. I found one regular size washer was just right. Hark to the fact that I am going back 20 years in my memory, and I may be thinking of the rudder tubes which had the same system on the RV 6.
