Bob will probably comment as I got a lot of flack when I reprinted it in the Experimenter. It has been printed and re-printed numerous times BUT it doesn't make it accurate.

Perhillian Designs has a solid-state driver that will work with them. Or you could use the RAC servo to position a lever (straight bellcrank) with a longer arm, trade torque for distance. Neal > I could use another .5" as I've run out of travel for the custom captured spring design on my elevator trim system. Anyone have any ideas?

I noticed in your FAQ that you weren't overly happy with the moving map software that you are running. You might want to take a look at www.pocketfms.com They have a PC and an iPAQ version. Good software, good support and... for free! I run it on my iPAQ and am very happy with it. Take care, Hans ________________________________ Message 6 _____________________________________ Time: 09:50:01 AM PST US From: "Jones, Michael" Subject: AeroElectric-List: mag switches --> AeroElectric-List message posted by: "Jones, Michael" hi all is see in my aeroelectric book on z-11 generic system that 2-5 switches are used for mag control, in the section under switches pg 11-18 however 2-3 switches are described for use on the mag controls, which is correct or are both correct if using the 2-5 switches i see there is no push button for a start, is this because of the spring loaded 2-5 switches, so what happens at each switch when starting the engine right mag, position 1 off, position 2 ??. spring position 3 ??? left mag, position 1 off, position 2 on, spring position 3 start then back to position 2 on guess what i need is what does off-start/on refer to on the 3 switch position thanx mike murphy rebel NOTICE - This message is the property of HATCH.

The multi-meters I have access to only measure up to 2 amps, but I'm sure my light uses more than that (on the order of 5-10 amps, I believe). Can you tell me where I can get an ammeter that measures more than 2 amps? Is it inadvisable to use the ammeter I will install in my plane? Any help is appreciated. Thanks, Grant ________________________________ Message 8 _____________________________________ Time: 10:35:49 AM PST US Subject: RE: AeroElectric-List: Measurements From: "Chuck Jensen" --> AeroElectric-List message posted by: "Chuck Jensen" Poor mans measurement. With your master on, check the amp draw. Turn no landing light and note amp draw. After that, the math is simple....and accurate enough to tell the difference between 2, 5 or 10 amp draw. -----Original Message----- From: owner-aeroelectric-list-server@matronics.com [mailto:owner-aeroelectric-list-server@matronics.com]On Behalf Of Tinne maha Subject: AeroElectric-List: Measurements --> AeroElectric-List message posted by: "Tinne maha" Bob/List, I would like to measure the current used by my landing/taxi light.
