The standard instrument panel is quite flexible anyway, to the extent that a g-meter installed in mine gets 'flicked' to stupidly high readings on a hard landing as the panel rebounds elastically. A resilient foam gasket under the panel mounting flange may provide some useful damping.

However, I decide to follow the instructions from the original build manual, and I am glad that I did, as I have never noticed a problem in the couple of years my aircraft has been flying. Obviously some pilots have had a problem (hence the MODS), but it has been my experience that it is best to build the aircraft as designed, only making changes when experience has proved them necessary. I have attached a couple of pictures of my panel, one showing the attachment points during the build, and one of the finished article. -------- Bob Dawson Europa XS TG || 912 ULS || G-NHRJ || Dynon Skyview || PilotAware || SmartAss3 Read this topic online here: http://forums.matronics.com/viewtopic.php?p=495982#495982 Attachments: http://forums.matronics.com//files/sg_cockpit1_157.jpg http://forums.matronics.com//files/panel_01_211.jpg ________________________________ Message 3 _____________________________________ Time: 07:53:01 AM PST US From: david park Subject: Re: Europa-List: Instrument Panel Advice re placement on Firewall options G-LDVO BUILT AS PER MANUAL NO RUBBER INSTALLED AND NOT HAD A PROBLEM IN 180 hours FLYING.
