I have been continuing wiring up the VPX and the avionics but mostly the VPX. In an effort to help with wire lengths and routing of wire I mocked up where the panel was going to sit and I made some mounts for it out of 4x4 so I could hang the panel without the dash to give me extra working room. With that done I have been pulling more and more wiring and I have now finished pulling all of the wire for the VPX. A lot of the wires are hooked up on both ends but I have a few more to be fully done connecting the power wires from the VPX. I also need to go back and lace all the wires where I am confident I am done pulling wire.

Another milestone is I finally decided where and how I am going to have all of my ground wires terminate. I haven't seen much on this topic on the forums and I even posted some questions with no answers. I went with a forest of tabs from Stein Air and mounted it in a mostly central location on the inside of the firewall. My son also help with mounting it by helping me remove the primer on the firewall where the tabs were going to be. After we cleaned the exposed steel I applied some No-Ox electrically conductive grease and bolted and riveted the tab plate in place. Now I can start terminating all those grounds.

I figured out where the 1.5K and 600k resistors go that I received from Midwest Panel Builders. They go to the Rotax lane lights. I soldiered them together as indicated by the Sling electrical manual. I dont know why I put two resistors per light the way that I did but I am just trusting in the instructions. I did test the lights with a 9 volt battery and they do still work.

I also went to mount my autopilot panel and was a little surprised when it went right thru the panel. It turns out I need the optional mounting bracket. I would have assumed the panel would have been cut to just mount the A/P right to the panel as it was designed. I can only guess Midwest was trying to keep the cut out in the panel uniform for aesthetics. Its not a big deal just another "oh I need to buy something else" moment.

lastly, I am trying to decide on a propeller, I was going to go with MT and the RS flight system but #1 they are expensive and #2 I have been hearing that they MT prop used with RS and the Sling has been having some problems. I have reached out to DUC propellers and am going to explore possibly using on of their props.
