Bigtime! Apparently the bungees are not tight enough and/or old. I have decided to go with the coil spring system. Several others including William Wynne have done a spring in a can system. It also has good reviews. I am inclined to do it the way WW describes it on his website. https://flycorvair.net/2015/05/01/steel-tube-pietenpol-fuselage-with-landing-gear-and-12-x-4-8- *tires/* The local welder looked at the system and like many non EAA types started talking about seamless tubing and much more expensive materiel. He said he would weld what I wanted. I just want to confirm with those who have built it. , The interior is a one inch rod. The Can is 2.25 ID seamed tubing. The washer inside is a 2 inch washer. The washers on the can are 2.25 washers. It is not a precisely machined item exept the welds should be square and flush. Anything else I need to know? Wag Aero sells a set for $319.99 and you still have to cut it to length and put eye holes in the ends. The spring is exposed. The system has good reviews. https://www.wagaero.com/wag-aero-kit-airplanes/sport-trainer/landing-gear-kit-options/sport-trainer-die-spring-shock-strut-kit-fabricated.html Opinions invited! -- Blue Skies, Steve D ________________________________ Message 5 _____________________________________ Time: 06:40:06 PM PST US Subject: Re: Pietenpol-List: DIe Spring gear From: "Andre B.

I absolutely agree with William's opinion that sitting taller on the gear looks better and gives a more positive 3-point landing. The tail on my airplane sits just a bit higher than some, so I think I get a little more float and slightly less solid 3-point landings than if it sat higher on the mains. The springs on mine are not captive, instead using the "Bingelis-style" sliding setup with bolts riding in slots. I've always thought that the slots create the weakest points in this spring strut system and they have more parts and fussing to assemble than William's "spring in a can" arrangement. I'm not sure where you're seeing that the Wag-Aero spring struts only cost $319.99 though. The link you provided goes to a page that shows them as $575.75. Given that they are for the Sport Trainer which grosses at 1200+ lbs, there should be no reason why the Wag-Aero struts won't work... and they are already assembled and just need to be fitted to length. -------- Oscar Zuniga Medford, OR Air Camper NX41CC "Scout" A75 power, 72x36 Culver prop Read this topic online here: http://forums.matronics.com/viewtopic.php?p=469135#469135 ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message pietenpol-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/Pietenpol-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/pietenpol-list Browse Digests http://www.matronics.com/digest/pietenpol-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
