Even if you have done radio kit assembly before, please read through all the instructions before you

start. This kit is a little different, in that the mechanical components are the part of the printed circuit

board. The instructions give you the scope of the project and an understanding of the techniques we

have employed. You will be assembling the kit using five pieces of PCB material, and when assembled,

form the electrical connections. There are solder pads, registration marks, and letter coded parts, that

match each other. When you tack and solder the components it will make a sturdy mechanical and

electrical assembly.

Page 2 Refer to the figure below for identification of the individual PCB parts. On all the mechanical assembly soldering you do, you will use the same technique. You tack a single tiny point first, and then check to see that it is square and aligned with the registration points.
Page 3 Notice that the pieces are coded with letters that will match up when you have them in the correct alignment. The first two pieces to be joined are the backstop and the base. Attach the alignment gage to the base using a 4-40 screw and nut as shown in the figure below. Tighten the screw after you have placed the backstop against the gage and aligned it with the registration marks.
Page 4 Use the same technique adding the leaf holders. Space the two leaf holders with the #2 x 3/4” long #2 nylon spacer, 2-56 x 1” long screw and one of the 2-56 nuts. Match the registration letters and alignment marks. Slide the leaf holder assembly between the alignment gage, up against the backstop and light tack the pad between the base and paddle leafs.
Page 5 This completes soldering the mechanical pieces. Continue the building the kit by soldering the electrical components. Use the figure below for the part placement. Parts placement figure Install the two 3 pin headers. Install J1, the 3.5mm audio jack where indicated. The attached cable for input to your transmitter is optional.
Page 6 Assembling the paddle lever components: It’s a good idea to assemble the hardware over a cookie sheet. Any hardware is difficult to find if dropped. Secure the paddle leaves to the holders using the hardware as shown. The hardware is small but with some patience and tweezers, can be assembled.
