Here are a few pictures of the mod I did to my aviator to relocate the "Zoom in" and "Target cam (Arcade) Trim (Sim)" buttons to a reachable area.
The Button at the top is the LSB button (Zoom), the one below it to the left is the RB (Target cam/Trim). This ws fairly easy to accomplish and took about 30 minutes once I figured out the correct wires. My good camera is broken and I had to use my phone for the pics so I'll try to explain in detal.
Here is what you will need.
2 push buttons (available at RadioShack $2.99 ea.)
Electrical tape
extra wire (speaker wire works well)
wire stripper
drill with appopriate sized bit (for new button location holes)
soldering iron
