Nuckolls, III) ________________________________ Message 1 _____________________________________ Time: 07:51:22 AM PST US Subject: RE: AeroElectric-List: Vans RPM Transducer IE VTACHGEN 12 From: Bob, I got their website from Van's, http://www.instrumentsales.com/ Vans could not give me any additional documentation. The website is rather limited. The way the Dynon doc reads is simply to set the pulses/revs to your particular equipment. I talked to Dynon and they admitted that this combination has been used before (and recommended because they don't sell an RPM transducer) but they do not document or support it directly. Yup, looks like a little experimenting is in order. I'll post my findings to Van's and the list as to make life a bit easier for others in the future. Thanks Glenn From: owner-aeroelectric-list-server@matronics.com [mailto:owner-aeroelectric-list-server@matronics.com] On Behalf Of Robert L. Nuckolls, III Sent: Friday, September 24, 2010 2:57 PM Subject: RE: AeroElectric-List: Vans RPM Transducer IE VTACHGEN 12 Seems like all the Van's folks use the EIS 4k, I'm using the Dynon 180 which is similar but different. What you're needing is the SCALE FACTOR for the transducer in pulses per revolution of the engine crankshaft. No doubt the setup instructions for the Dynon will tell you what calibration code or dip-switch setting to use for that particular transducer scale factor. Unless someone on the list has installed that combination of hardware items or incidental access to those two values you're going to have to do some legwork. Does the transducer have a brand and part number on it?

I remember seeing an article on how to fabricate hold-down screws for db connectors installed with no shells, but now can't locate it. I know it's not exactly rocket science, but would like to re-read the article. I'm pretty sure it was aeroelectric list related... Thanks! -- Regards, J.

A Lancair builder put me on to these screws AN500-AD4-7* which I ordered from aircraft spruce. They are drilled fillister head screws and were perfect for the task.

I'd like to disable the flaps-down function if the airspeed is above some reasonable value. I can find electronic sensors, but I'd like to eliminate any electronics for simplicity.
