Just a thought...Jury struts should not be mounted at the center of the lift strut. Theyshould be offset a few inches. With them being in the middle there is equaldistance of the strut on either side. Either side of the strut will have aresonating frequency that is the same as the other. This COULD cause acondition where the struts begine to vibe at that frequency and get out ofcontrol until it literally shakes itself apart.Now... that's what the math tells us.... In reality the Piet probablydoesn't get going fast enough to see this condition..... but what theheck... it takes no extra time to install them offset a bit. Typically theyare offset to the outside of the wing.DJ VeghMesa, AZGN-1 Builderwww.raptoronline.comN74DV-----Original Message-----
