Bob & all, (third try at posting this request)
I'm looking for a review of my electrical system, based on Z-19RB. This is a retrofit in my little 22 year-old composite Quickie Q-200. I do a lot of day VFR cross country with this little buggy and do some cross country racing. Since I am converting to "all electric" I would be interested in your thoughts about my proposed system which is attached as a PDF file.
Besides the Dynon FlightDEK 180 the biggest change is the conversion to electronic fuel injection. I am using the EC-3 controller from Real World Solutions (RWS). You can see more about the controller here: http://www.rotaryaviation.com/eficont.html
The EC-3 controller is divided into two sides, A & B. The fuel injector control and ignition outputs exit the box from a single connector via a shared relay. The controller can receive either a primary or secondary 12V power source.
A few bullet points:
* I am using a primary fuel pump and a backup fuel pump. I also have two transfer pumps.
* I have not yet sized the batteries.
* I have an existing AEC9005-201 low voltage monitor, without the relay control.
* Output of the ECU will be shown on another page, perhaps later in the week.
* I have not yet properly sized the fuses or the wires in this drawing.
My concerns:
* By the time I add strobes and position lights, I will have around 14 or 15 switches, which seems like a lot for a 650 lb. (empty weight) airplane. Is there a way I could minimize the switch count?
* There seem to be a lot of components connected to the unswitched battery busses. I wonder if I should use CBs instead of fuses?
* Since I rarely fly at night, is the main buss, as depicted, really needed? Maybe I could combine the main and E busses.
Anything else? Your input is very welcome.
Thanks!
