This is the elevator control arm. It goes in the top section of the frames. The key to getting this together is to make sure you put the 'A' arms (14) on the correct direction. If you put them on backwards you might crack them. Test fit each A-arm. Place the link on a ball (the swashplate would work for this test), don't snap it on, just push it against the ball and notice how far it goes on. Flip it around and try the other side. The side that goes on further is the correct direction and needs to go toward the center. Install them on the elevator control arm (15). Make sure you have the side with the flat surface up and keep it this way when you install it in the frames. You don't get it upside down. This would then make the A-arms backwards.
After you get the A-arms on and pins installed, you need to install this assembly into the frames. Fold the A-arms straight out then angle the assembly about 45 degrees and insert it through the top/back of the frames (as viewed in the 3rd picture). Once you get it inside, angle it back flat (with the flat side facing up). The round center pivot points will fit in the slots on the left and right sides.
