Trick parts for adding Ailerons to your slow stick. These horns are special and differ from the tail horns. Comes with servo mounting pads, stick these down with Foam Safe CA, GWS glue included with Slow Sticks or any other foam safe adhesive. Pad is made from 1/64th aircraft ply so it is flexible and will match contour of wing easily. Glue servo (CA or Goop) to pad. (servos glued directly to the foam can be torn off easily). Spacers are provided so you can adjust horn to fit 4 or 5mm thick wings. Enough parts to do both ailerons on one wing. The aileron is cut out from the stock GWS molding on the back of the wing. Here is how I did it.
Instructions:
1.Press hobby pins through the color side at the corners of the aileron hinge line depression molded into the wing. Glue a balsa block to the side of your hobby knife so only about 1/8" of the blade sticks past the block. This block becomes a stop for the next step to stop you from cutting too deeply. Flip the wing over and put a steel straight edge against the pins (we are now working from the white or bottom side of the wing). Use your altered hobby knife to slice the foam from pin to pin in a straight line without piercing through the top surface or colored skin of the wing. 2. Line up a steel straight edge on the top surface of the wing and cut the cordwise lines (those going for and aft) at the ends of the aileron. Once cut, Move your rule over about 1/32" and take an extra sliver out. This way the edges of the aileron won't touch and bind as it moves back and forth.
3: Aileron is now free. Flex the aileron towards the colored side and the foam will crack up (from the bottom) to colored skin.
4: Hold the aileron so it's vertical or 90 to the top surface and use a sanding bar to sand the hinge line down flat so that both the wing and the aileron end up with a 45 degree bevel in the hinge line. BUT WAIT! When you sand, do so carefully, as you see the color (of the top surface skin) begining to peek through the foam, stop sanding. You don't want to cut this skin. The top skin becomes a living hinge. I added Blenderm tape to the bottom of my hinge line while it was flexed up to make sure I had a durable hinge.
Step 5 Warning! Your making each wing a mirror image of of the other, look carefully so both servos are placed opposite each other, pads are betweed same ribs and offset to similarly relative to the center of the wing.
5: Glue servo pad to wing. GWS foam glue or any other foam safe CA may be used. After the pads are cured, glue your servos to the servo pad. Cut the slot in the aileron so the holes in the horn are lined up over the hinge line you just cut in. Use the spacers (one long one aginst the foam) so the when the clip is installed the horn is snug. Remove, add glue and put back together. Make pushrod from .055 wire (same stuff used for slow stick pushrods) and your done.
