(Matt Dralle) ________________________________ Message 1 _____________________________________ Time: 06:09:30 AM PST US From: Denis Walsh Subject: Re: RV-List: Matco nose wheel axle I have to admit that after 4500 landings the problems with nose wheel in the RV 6A are still mysterious to me. Still I believe that tire scuffing is the most serious problem, causing flats and perhaps shimmy. For the past year I have been using 40 psi in all three wheels, no flats and no shimmy. easier to shove back in the hangar. If I were you I might give it a try.

No rubbing and less shimmy than with the Vans nosewheel bearing design.

Yes .. the antennas are sold separately .. the Delta Pop blade is on the site (I think about $59.00) ... the instructions (which you didn't get) list the GPS antennas that are compatible. The least expensive I could find was the RAMI AV-GPS for $209 on Spruce. Give them a call for the lastest install instructions.. they'll send them to you as a PDF. Have fun... David W.

Listers, I got a voicemail and a nice email from Bill at NavWorx this morning. He confirmed that the unit doesn't normally come with the antennas anymore, but he graciously offered to send me a UAT antenna free of charge. That was really nice. Bill also included the latest version of the installation/operation manual in PDF format along with his email. He said that they are working on adding the manuals to the web site, probably in August sometime. So, I'm good to go. I'll report later on my installation experience. Looking at the wring diagrams, it seems like it should be pretty straightforward connecting up between the GRT HX's and the 327.
