This, however, should definitely be added. As mentioned, most people use a cable look, BUT if you go that route, be sure to make it sturdy and use a few nico sleeves if you use nicropress sleeves. I personally know someone who's bungee's failed on one side and the "backup" cable slipped through the sleeve. Busted prop and an upside down airplane resulted. I made a "U" of thin aircraft tubing, flattened both ends and affixed it to some of the AN3 bolts holding the lower "V" brackets together. Can't say how it'll work, but should be sturdy.

Just wanted to make sure I wasn't overlooking something in the plans. This looks like one of those areas where it might be fun to get a little creative with engineering. Rick, in the photo you posted, I'm guessing the downfacing rod is both a guide pin, and to keep axle from rotating with brakes. I might try to come up with something that is both a safety cage and rotational stop. If I get some time I will have to look at ideas on West Coast Piet. -------- Jon Jones Ironton, MO Read this topic online here: http://forums.matronics.com/viewtopic.php?p=464844#464844 ________________________________ Message 3 _____________________________________ Time: 12:28:35 PM PST US Subject: Re: Pietenpol-List: Re: Wood Landing GEAR From: Richard Schreiber Jon, Your are right, the down tube is an anti-rotation device since this set up has brakes. The photo I sent is not of my plane, though my set up is the same, but of Mike Cuys. A little more elegant way to set up the "safety strap" in case of bungee failure, is a modification of the loop seen on Mike Cuys plane. This is similar to what Dowe spoke of, but still uses a cable. The photo is a nice example on Dan Helspers plane. I just used a loop, but that was done an hour before first flight last year. I will do what Dan has done using 1/8" or 5/32" 1x19 cable as soon as I can. I am sure it will be strong enough.
