Up early this AM to final install the ELT and Garmin GTR 20 Remote Radio. The ELT's tray sits on three tabs welded to the fuse with lock plates installed in them. I wanted to have some vibration dampening so I purchased some large rubber fender washers to go between the tray and the fuselage. This will eliminate any noise from vibration.
I installed the ELT, it's custom tray, alarm, and antenna, tightened all the nuts and applied torque seal.
Next up was the Garmin GTR 20 Remote Mounted Radio. I got so excited about installing stuff that I got ahead of myself and installed the radio without weighing it. So, I had to remove everything, clean all the torque seal off, weigh all the components, then reinstall it. The installed weight of the radio and all the components = 2.10lbs.
I used six 1/4" thick rubber washers as standoffs between the radio and the tray. First, to give the radio some cushion from vibration and second, to allow some cooling air flow around the radio. Once the radio was mounted to the tray, I mounted the tray to the fuselage using six Adel Clamps.
I had mounted the Garmin Pitch Servo last night but after looking at it this morning I was not happy with the bolts I used (AN3-3). They were barely adequate but I reconsidered and decided to install the next size up (AN3-4). I prefer having a few threads exposed beyond the nut. In reality the bolts I had in place would be fine, but I just wanted to do it correctly so I took it back out and cleaned all the torque seal off the nuts and washers, and reinstalled with the longer bolts. I re-torque sealed everything. Happy now.
All three components installed...
