Hi, I'm looking at a steel tube fuselage for sale, but it's the standard length.Does anyone know if that will work with a corvair motor (weight and balance)?Thanks. jamesRead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Re: Pietenpol-List: Standard fuselage/corvair motor

Hey Michael,As mentioned, my axle fairing (Jenny style) is fabricated from aluminumsheet. Ply should work fine (did in World War I?)I attached mine by welding three sets of tabs on the spreader bars to whichI bolted three aluminum "ribs" to which the rest of the structure rivets to.The axle sits in a trough covered with a hinged flap, held down by somelight springs so the axle can come up to it's limit by just lifting the trapdoor. During normal axle movement, I don't anticipate it hitting the doorat all, but we'll see.The entire assembly weighs a bit under 3lbs and should reduce the drag fromthe axle and spreader bars, and might provide a couple pounds of lift. Allthat being said, I really did it because I thought it looked cool and I feltthe weigh penalty was likely canceled out by the drag reduction.Can send pics if you likeDouwe________________________________________________________________________________Date: Tue, 3 May 2011 09:12:30 -0600Subject: Re: Pietenpol-List: Standard fuselage/corvair motor

Hi James,Confusion is a normal state of affairs on this list - if you doubt it start looking through the archive . Seriously, though, the answer to your question is "it depends". Mike Cuy has an A-65 on a standard length wood fuselage, there are people with model A's on long fuselages, corvairs on long and short fuse's, just about any combination you can think of. It really depends on how YOU build the plane. I'm sure that helps .Kip GardnerOn May 3, 2011, at 11:23 AM, james theissen wrote:> >>> OK, now i'm really confused.

Hey Jeff,I am sure this will work. Those structural rivets will be just fine. With four struts the load is spread out. I would maybe tighten-down on the lower strut attach bolts so there is no movement; no chance of elongation of aluminum holes.Dan HelsperPuryear, TN-----Original Message-----
