That just wears out the controls. I have run this same radio in 2 planes over the last 15 years, no problems. It was in a C150A with the pull starter and generator, no avionics master, not even the 'dump the radios while the keyswitch is cranking' facility. Those 'older' radios are compliant to DOD 160, something that some of the newer round hole mount types seem to be lacking. You can tell the cheap ones by the messages on their websites about "must install after avionics master and xx,000 uF capacitor" The problem with these is they actually have no physical switch of their own, and the electronic switch is 'susceptible', so this class of device does benefit from a separate switch. I'm with Bob's philosophy here, and if things go bad on a murky day you really just want to fly the airplane without getting mixed up in complicated systems that lead to more troubles than you started with. Sorry it doesnt make for a very impressive cockpit, bit like when I got into a Piper Cub after training in C172's and literally wondered if I could safely fly this machine because it lacked almost every item that I thought was needed for the journey. And it didnt have an avionics master.

I'm taking for granted that the remote magnetometer and the vertical card compass are not simply duplicating each other's errors since they are situated very close to each other. You have probably checked their readings on a compass rose with everything turned on and running, right?

This is useful not only that you have a reading of the air temperature, but it also means that the airspeed will be corrected for altitude and temperature. By the way my remote head is in the back of the luggage rack. Tim Shankland Thanks for all your replies. Seems that the tail is a better place to mount the remote compass. That means that I can put off the purchase for a little longer.

Wade Jones South Texas 601XL plans building Cont. 0200 ----- Original Message ----- From: Terry Phillips To: zenith-list@matronics.com Sent: Friday, November 09, 2007 12:03 AM Subject: Re: Zenith-List: riveter nosepieces Darrell I have a Central Pneumatic riveter and a couple of HF hand riveters. The riveter heads for any one of these will not fit any of the others. I haven't tried to get back-up heads, but that seems like a good idea. I have found that the pneumatic riveter is too large diameter to set some rivets, so I used a hand riveter for those. I suggest that you buy the pneumatic and hand riveters at the start and send the heads for both in one shipment to ZAC to save postage. You only need to send the heads for the 1/8" and 5/32" rivets. I just painted all my A5 riveter heads red. Don't ask why I decided this was a good idea.

I did finally buy the nose pieces from Zenith. I use them on the cheap pneumatic Harbor Freight riveter powered by the $89.95 HF 2hp compressor. I would recommend the nose pieces from Zenith. These three tools are the some of the most used tools on the project.They are a bargain especially if you can buy the riveter and compressor on sale. I think I have about $150.00 invested in all three. Would not attempt the project without them!
