Install the pitch arm (22) onto the frames. Install the (8) bearings into the middle hole in the left and right side of the pitch arm. The center of the (8) bearings need to align with the holes in the frame that I marked with red arrows. After you get it in place you can insert the elevator control arm (15 from the previous page) in the the loops at the back of the pitch arm. Next start on the left side of the pitch arm and slide the small sleeve (10) on the screw (2). Now put a small drop of CA on the tip of the screw and install it into the left side of the pitch arm. If you get the screw too tight then the pitch arm (22) will not pivot freely. Now for the right side. The picture from the orginal manual makes it a little hard to see the small parts. If you look at the second picture you can see I edited the orginal so the background is removed.
Insert the two (7) bearings into the elevator control lever (21). Slide the sleeve (9) onto the screw (3) and then insert it through the bearings of the control lever (21). Slide the small washer (11) on the screw (3) followed by the sleeve (10). Screw this through the (8) bearing you already installed and into the frame. Make sure the pitch arm can still pivot freely. Then slide both balls (13) on the screw (4) and screw this into the elevator control arm (21). Make sure that the shoulder side of both balls face the arm (21).
Next install the link ball on the front of the pitch arm. There are two positions. If you are an advanced pilot then use the back hole. If you are just starting out and don't have a computer radio or you do but it is a Futaba 6X series then use the beginner hole in the front. All others use the back hole. The back hole will allow full collective range. Yes, you could get full range out of the front hole with a long enough servo arm, but that would make the servo have to work harder and because the pivot point is further out on the plastic pitch arm, this increases the amount of flex in the system. In other words, it's technically better to use the inside hole.
