22-Elec.&Avionics
Chapter 22 Electrical and Avionics
The two hardest decisions for the project are the avionics and the wiring diagram.
I am intalling a full IFR, "glass" package and an engine controller and monitor specific for the Renesis rotary.
Some builders use a panel design software. I decided to go "old school" and went with a paper template of the IP and I cutout paper templates of all avionics and intruments and moved them around for best position. The placemet of my manual front LG "rod" and my parking brake and heater controls are already set and a paper template shows those better than anything else. Also, I have the larger pictures of the componets.
As for the wiring diagram, I selected one from Bob Knuckolls' book Aeroelectric Connection. I will use the Z-19/RB diagram. That is for a two battery, one alternator, and EFI engine. I will make a mock up of the IP-conduit-FW and make the wiring harness and transfer that to paper for the wiring schematic to keep with the POH. I will use the number group system for labeling and on the schematic as referred to on page 1-5 of Bob's book. Bob seems to not like a lot of colors for wires, but I will use white and black(grd.) and number them. Bob's book is great.
Now, here are some pictures of what is on the IP.
Thanks to Ben Myburgh, IFR instructor, for his help in the panel selection. The core of the panel is the Dynon Skyview system and the Garmin 430. Next shown is the Garmin 240 audio panel, then the Garmin SL30 Nav/Com and the Narco transponder. I added the backups of airspeed, attitude and altimeter (all are Falcon). The pilot side will be the 10 inch primary display and the copilot side will have the 7 inch display to leave some IP real estate for future addons.
The Renesis rotary is not supported by the Dynon engine module, so I am using the "ECU" EFI ignition controller (EC3) and the engine monitor, EM3, from Tracy Crook at Real World Solutions. I will use the EM3 for the engine monitoring and add an "old school" type Falcon dual tank fuel gauge for the signal inputs from the 0-5 volt Princeton fuel probes. The Dynon engine monitor supports the Lycoming engine, but not the Renesis engine. If it were possible, I would like to add some of Al Wick's ideas for my IP.
