Brief Description:  Avionics planning; horizontal stab mounting

A momentous and productive day! Last night, I researched the dimensions of all the avionics I plan to install, just to verify the suitablility of their locations in the panel. I'm glad I did this, because I soon realized that if I placed my radios and transponder where I'd originally planned, it would severely limit my ability to mount items on the avionics access door. The Garmin 430W GPS/nav/comm, SL-30 nav/com, and GTX-330 transponder are very deep units. These will have to go on one side of the panel, not separated like I'd planned. The audio panel is a much shallower unit, and will fit on the right side of the panel while still leaving plenty of room for the electrical buses behind.

I decided to take a big step today. My horizonatal stabilizer has been hanging in a cradle on my hangar wall for over five years. Its presence in my hangar was a constant reminder of my uncompleted airplane project. It has silently marked the time since my airline employer's bankruptcy and has been, in a way, a symbol of all my career frustrations. Despite my employer's continuing financial difficulties and my career's instability, I decided to jam a stake through all the demons.

With the help of a friend, I leveled the fuselage, removed the horizontal stab from the wall, and clamped it in place on the fuselage. I spent an hour studying the tail-mounting process in the assembly manual and reading the plans. Very satisfying. I now know I WILL finish this airplane, no matter what happens to my career.
