I used doug fur,but the grain was running the wrong way so I cut 5/8 wide strips and epoxied them atop eachother. then I planed the new board down to 3/8 inch and laminated on 1/8 okume ply on each side and lastly epoxied rails to make an I beam of 1inch wide along the rails and 5/8 in the web. I didnt put stiffeners behind each rib attach location for the center section but will be doing so for the left and right wing. -------- Paul Donahue Started 8-3-12 do not archive Read this topic online here: http://forums.matronics.com/viewtopic.php?p=464169#464169 Attachments: http://forums.matronics.com//files/img_1924_756.jpg http://forums.matronics.com//files/img_1896_117.jpg http://forums.matronics.com//files/img_1893_726.jpg http://forums.matronics.com//files/img_1916_205.jpg ________________________________ Message 2 _____________________________________ Time: 05:34:36 PM PST US Subject: Pietenpol-List: Re: Sky Scout From: "iowaboy" A suggestion would be to make a new motor mount that would be longer so you would move the weight of the engine and prop forward to help you weight and balance??? This way you don't add that much weight to the plane. Now maybe that is not a good idea? I have heard of others who had other designs who did this to help weight and balance.

The problem with that is removing the engine, the making of the mount, re-installing the engine, building a new cowling and painting it. I am moving the wing back and checking on using a metal prop. Moving the wing does the most good, even more than the motor mount....especially considering the amount of work involved. All the calculations have been kinda fun. Especially with Scott Liefeld's generous help and his putting me on the right path. But building a Piet is a journey to be enjoyed and not to rushed. I may end up doing all of the above! It's too cold to fly it this time of the year, anyway! And if I can't shake this lousy cold, I might lose ten lbs. off my butt? Thanks for your suggestions....build'em light!
