My antenna is mounted inside the nose cone and the coax runs about two feet back to the built-in radio. That may have helped. Tkx I think I'll attach more. I am trying ALL suggestions to reduce radio noise, as I like to hear traffic and control towers, a/ Ferrite chokes on the Antenna. Antenna in nose cone (Shortest route to radio) b/ Reduced the wiring to the headset plugs, Used shielded wiring. c/ Am covering the sparkplug leads to shield them. d/ I have not yet directly attached the Radio positive and neg to the battery but I have attached ferrite chokes along the power cable. e/ I am using a Noise cancelling headset but earbuds may also help. Any other suggestions??

I ended up with two after ordering one which must have been shipped on a mule, so out of urgency I ordered another one, ergo two. Of course they were both delivered on the same day by UPS, one after two weeks on the road and the next one after three days on the road. go figure!

Phil H/Kolbers: Garmin Etrex GPS is great for a pickup truck to determine speed, but it will not give you airspeed. GPS gives you ground speed which doesn't take wind into consideration. Recommend flying your Kolb with an airspeed indicator, as a minimum. The airspeed indicator is the most important of all instruments in an airplane. Something to give you stall and VNE speeds. john h mkIII Titus, Alabama le, List Admin. le, List Admin. -- kugelair.com ________________________________ Message 5 _____________________________________ Time: 01:51:32 PM PST US From: Dana Hague Subject: Re: Kolb-List: Skywriting in a Kolb?

Can't see why not, if you put a smoke system on your motor. Might make a mess on the prop though, most planes with smoke systems are tractors. -Dana -- I don't like the idea of term limits for politicians.

Shouldn't require any aerobatics, except tight turns perhaps. I know it requires careful planning (time and turns) though modern GPS would probably make it a lot easier. -Dana -- Anyone who cannot cope with mathematics is not fully human.

If so, how? > John, Nikasil is a trade name for silicon carbide (a ceramic) particles that are fused to the aluminum cylinder wall in a nickel (a metal) matrix. The silicon carbide gives very good wear properties, and the nickel provides very good thermal conductivity. The total coating thickness can be any where from 0.002 to 0.004 inches thick. With improved heat transfer through the coating to the aluminum cylinder, one can run very tight piston to bore clearances with less fear of cold seizure. Also one can run higher EGT with out fear of melting the pistons. With reduced piston to wall clearances, one can run simple very thin, light and inexpensive piston rings. When I purchased the Victor 1+, which has a Nikasil coated cylinder, I asked about TBO. I was told to replace the piston rings after 600 hours, at 1,200 hours replace the piston and rings, at 1,800 hours replace the rings, and at 2,400 hours to replace the cylinder, piston and rings. As to if ceramic is tougher than steel, carbide ceramic tool bits are used to machine steel and cast iron parts. I hope this helps. Jack B.

Do you have knowledge of an owner that has attained this much time on a Victor? I wonder if those figures are for the user or lab environment? john h mkIII Titus, Alabama ________________________________ Message 11 ____________________________________ Time: 07:55:27 PM PST US From: "Jack B.

Do you have knowledge of an owner >that has attained this much time on a Victor? > >I wonder if those figures are for the user or lab environment? > John, There are other ceramic coatings that are used as thermal barriers that can be applied to the top of the piston, the head inner surface and the exhaust ports. When these have been applied, one can run higher EGT's. I do not know of anyone who has run a Victor 1+ up to these hours. 600 hours for a ring replacement is not all that high when little four cycle diesel engines run several thousand hours with no ring replacement. Also in searching the web I found: http://www.ncccoat.com/PDF/NCCSAEtechnicalpaper.pdf and: http://www.mt-llc.com/tour/98winter_snowtech_article.pdf The first is pretty technical. The second describes repair. I suspect these hours were found by running an engine for a given number of hours and then the engine was torn down and measurements were taken of the rings, piston, and cylinder. And then from the wear found, extrapolations were made to come up for the TBO, ring, piston, and cylinder replacement. Jack B.

Hart FF004 Jack H/Kolbers: Not really any comparison between longevity of a diesel four stroke and a gasoline two stroke. There is a facility in Auburn, Alabama, that recoats cylinders. I rebuilt my son's 450 Yamaha MX engine. The cylinder was really buggered up. They did a good job, but it was expensive. Good luck with the Victor. john h mkIII Titus, Alabama ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message kolb-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/Kolb-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/kolb-list Browse Digests http://www.matronics.com/digest/kolb-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.
