I can't remember this question being asked. Probably because it is soobvious, but I can't see it.If you have to move the wing to balance the center of gravity doesn't thatthrow off the alignment of the upper bolt holes where the lift strutattaches to the wing? How do you handle this? Make the holes big enough toallow for the movement? Hold off on drilling or welding until you knowwhere the wing will be placed?Help.Thanks, Ted BrousseauGlad to be moving along enough to ask this question.________________________________________________________________________________

I don't know of any other aircraft, that has the plans type fittings on both ends of the struts designed to allow movement of the wing. Ya just loosen all the hardware on the struts and cabanes, and move the wing to the new location, andtighten them back up, and use paint or torque seal on all the hardware. Do Notoversize any holes. All drilled holes should be a good fit for the bolt. If the wing has to be moved very far, new cables will have to be made up for the lift struts, and the cables on the right side of the front cockpit. Note: I've never heard of the wing needed to be moved forward, it's always moved aft, to compensate for the notourious tail heavy condition of Pietenpols. This is because B.H.P. was only about 160 lbs, and today's flyers average around 200 lbs. This sets up the tail heavy condition. Moving the engine forward a couple of inches from plans location, will help...especially if you'rethe type that doesn't miss any meals !! :)Chuck GantzerNX770CG________________________________________________________________________________

Henry,Yes.Some guys do the X cables till they get the wing position, CG where theywant it, than change to the hard cabane type after they know how long tomake them.Skip>>> My question to the group is:> If you use the hard ( cabane strut type - or - rod and fittings ) fromthe > top engine mounts back to the top of the front cabane struts, doesnt thisgive > the needed rigidity so that you can do away with the right hand side Xcables?> Henry Williams ________________________________________________________________________________

I did everything I could think of and decided to fly it a few milessouth to the best shop around Dallas. The engine began to run rough on descentand failed on landing. A wrist pin had worked it's way up against a cylinder wall and made so much metal that it clogged the oil fliter. The engine was junk.The engine had 364 hours since one of those high-dollar blueprinted overhauls by Ultimate Engines of Mena, Arkansas. The good news was I had a "520 hour unlimited warrranty". The bad news was new owners had bought the assets but notthe liabilities of the old owners of Ultimate and refused to even discuss a warranty claim. I had to pay for another overhaul but you can bet it wasn't fromUltimate Engines.
