Garmin Brackets Finished and More Avionics Planning

Last night before I went to bed I decided I needed to 3d print the components I was going to be installing in my system so I could plan space, cable runs, etc. And below is the fruit of my efforts (granted Garmin provided the models)

The first one is the Garmin GSU 25C ADAHARS unit. This will take my pitot static system and also it’s installed plane to give me my speed, altitude, AOA, and attitude. This combined with the magnetometer give me the entire picture of where the plane is oriented and at what speed. The second unit is the Garmin GAD 27 which allows me to interact with the lights, flaps, trim, etc. I won’t be using it for the trim as I will be connecting the trim motors up to the Garmin autopilot servos, but I will use it for the lights, flaps, and interior lights so far. There are other features that I’m determining how I will use them, etc.

I then spent quite a bit of time working out my primary electrical system. I will need to buy some firewall penetration posts that will allow me to pass the heavy gauge wire through more easily without the worry of it chaffing. These posts will allow me to attach the lugs to them and secure the connections as needed. There are other components that I need to discover too as I saw on quite a few installations that they had a grounding bus bar with quite a few components terminated to it. I’m not sure how many I will need but I’m going to guess there are quite a few sensors that need power that I can put there. I need to dig into this and what the Lycoming engine and Garmin GEA 24B will need to monitor the IO-540 properly.

I also got a TON of hardware sorted out and I would have finished the job but I ran out of labels to print on. So while I ordered and wait on that, I decided to finish the Garmin yaw servo mount install. I got the four rivets drilled out and installed the bracket without too much hassle.
