The VR166 type Ford regulator (mid-70's LTD) that 'Lectric Bob shows in some of his schematics and many of us use is solid-state and doesn't have any adjustments. Since it only costs about $10 it is easy to replace if it has drifted out of spec. But they seem to be very reliable units and mine has been fine for eight years.

This event has been happening close to 40 years and is one of my favorite fly-in's to attend. It is a well run event that does not have a real structured program. It is an aviation social event and the main rule is for you to have a good time. If you are tired of poorly run events with bad facilities, give this one a try next year. It happens the second week-end in October every year and is open to all types of aircraft. There is also a great private collection aviation engines on the field. It is always open for viewing during the fly-in and contains rare engines you might not have ever heard of. Go to http://picasaweb.google.com/RV455J/Thomasville2007 for a few pictures from this year. ________________________________ Message 3 _____________________________________ Time: 06:32:59 AM PST US From: Richard Seiders Subject: Re: RV-List: PC-680 Performance --- MIME Errors - No Plain-Text Section Found --- A message with no text/plain MIME section was received.

Regards, Jim Ayers -----Original Message----- From: Kyle Boatright Sent: Sat, 13 Oct 2007 7:07 pm Subject: RV-List: PC-680 Performance Over the years, the Odyssey PC-680 has gotten very good reviews for its small size and high cranking amps. So, about 3 years ago, I selected one to replace a 4 year old Concorde battery. My first Odyssey battery became weak after just under 2 years. The vendor replaced it under warranty. Today, my ~14 month old replacement battery barely turned the engine over on a 80 degree day. Sure, the aircraft sat outside in 45 degree weather last night (Thomasville GA Fly-in - a really fun one), but the airplane had 8 hours of South Georgia sunshine to warm up, so is isn't like the battery was chilled or anything. To get to the point, what is the RV-list's collective experience with this battery? I know it is light and has good cranking power when new, but I'm interested in what sort of longevity people are seeing. Is it lasting 1 year, 2 years, more, or less? I'd hate to go back to the Concorde, but I'd prefer that to a battery that goes soft after less than two years. KB _____ Email and AIM finally together.

This location also ensures a straight line prior to the inlet. I've read on previous post that it is better to have the sensor level, how critical is this?

The aircraft had sat for 2 days since its last flight. Then, I went flying. The engine's starting performance was *much* better than on Saturday. I checked the charging system's performance several times on the ground and in the air, and the system voltage was always 14.2 - 14.5 v. After I landed, I let the aircraft sit for long enough to roll it back in the hangar, and checked it with the meter again. The reading was 12.8v. So, the question is: Was Saturday's reluctant start a freak event caused by unknown reasons? Or should I expect to see more than 12.6 - 12.8v on a "charged" battery? I know that 14.3-14.5v output from the alternator is within the appropriate range. Thanks in advance.

Also, on standard lead-acid batteries, heat can affect their performance. Most people think a battery is most likely to "act up" when it's very cold outside. They also "act up" when they are hot (like in places like Georgia)....No idea what makeup the PC-680s are... http://www.engineersedge.com/battery/discharge_rate_temperature_effects_battery.htm Scott http://corbenflyer.tripod.com/ Gotta Fly or Gonna Die Building RV-4 (Super Slow Build Version) Kyle Boatright wrote: > After Saturday's marginal starting performance, I thought it was worth > getting quantifiable measurements on the battery and charging system, > so today I checked the battery and it showed 12.6v.

This is true, but keep in mind that 13.2 is at zero load. If you are reading the voltage by turning on your electrical system and reading the number off your volt meter, I wouldn't be surprised if there is enough in your system to draw the voltage down somewhat. 12.6 seems pretty much in the ballpark. -Rob ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message rv-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/RV-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/rv-list Browse Digests http://www.matronics.com/digest/rv-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.
