    Cc: Dick Navratil <horzpool@goldengate.net> --> Pietenpol-List message posted by: <glennthomas@charter.net> What I've come to learn is that if the end grain is vertical, then the grain cannot be straight on the side faces. But the specs say 4 faces. Yesterday I met with a friend building a Flizter and he told me to not be so fussy witht he capstrips because of all the gussets. My gut feeling is that I should be looking for compliant slope on the grain if the piece is quarter cut, or ignore if the grain is vertical if the top and bottom look OK.

    Barry Thanks for the Brodhead dates. I'm Bob Humbert in Battle Creek Michigan. I have a Piet project that I started in 1969. It is finally (hopefully) in the final stages of completion. Power is C-75-12. It is now out of the garage and in a hanger in Marshall Michigan, with the wings on, engine mounted, etc. There are a few issues to resolve with the engine then it should be ready for inspection. I was afraid that Brodhead would be that weekend. That weekend I will be working as an official at a national hot air balloon championship in South Carolina that weekend. That event has conflicted with Brodhead for a number of years. I will probably have a chance to visit the Brodhead airport again in June while I am working a hot air balloon event in Monroe WI. I have worked the balloon event in Monroe in June for a number of years now and have taken the opportunity to have a look at the planes and projects at Brodhead while I'm there. regards!

    --> Pietenpol-List message posted by: harvey rule <harvey.rule@bell.ca> Just riding in on this old message here to ask why most of you guys don't enclose the landing gear in fabric?I noticed a few had it done in some of the photos but most where open.Is this personal preference or is there a reason?Since in most cases the landing gear is of a cub type,I would think it would be enclosed.How does this effect flight characteristics?If at all.

    Subject: Gear Leg Fabric & Crosswind Landings
    In a message dated 4/15/2006 7:49:18 PM Central Standard Time, harvey.rule@bell.ca writes: Just riding in on this old message here to ask why most of you guys don't enclose the landing gear in fabric?I noticed a few had it done in some of the photos but most where open.Is this personal preference or is there a reason?Since in most cases the landing gear is of a cub type,I would think it would be enclosed.How does this effect flight characteristics?If at all. I seem to remember BHP wrote that the fabric covering on the split axle gear, adversly effects crosswind landings. Very little doubt that is correct, especially like the crosswinds I was facing last Wednesday. Last summer, I faired in the round tubing on the gear legs, and I'm glad I did Not put the fabric on the legs !! I show how I did that on one of the pages of my web site. Chuck G.

What would you do >> differently with this in mind? >> >> Thanks. >> Something to think about though before you do beef it up. If you really hit that hard, do you really want the gear to stay intact? The energy is going to go somewhere. You could probably build the gear strong enough to take it, but the energy of that impact is going to be transfered. In this case the thing that could give is your back. Id rather fix a landing gear and prop than order an electric wheel chair. How strong is too strong? I don't have the engineering expertise to say. Someone here might. Yet the Piet has been around for an awful long time. There hasn't been what I would consider a rash of gear failures in reasonable landing conditions that some airplanes have experienced. ( if there has been I haven't heard about it and would welcome the chance to be educated) If people were breaking gear all the time, I would definately beef it up. Insurance doesn't always come in the expected package. That breaking gear might be your insurance.
