Taboo GT - Top Drive Wing Servo Installation

1. Make a servo pocket on the bottom surface of the wing as usual. The servo must be flush with the bottom surface. If the servo is much thinner than the wing (unlikely) then you may want to make the pocket deeper to put the servo against the top skin, and fill the space above the servo with balsa later.
2. Attach a long servo arm to your servo, position it in the servo pocket and mark the location of the skin opening. You can poke a small hole with X-acto knife or just make a dot with a pencil. You must be able to see this mark from the top surface of the wing.
3. Use masking tape for cleaner skin cuts. Draw the outline of the skin opening for the servo arm.
4. Cut the skin opening with X-acto knife. Check the alignment of the servo arm. Ideally there must be no rubbing on the sides, and the length of the opening must be sufficient for full servo travel.
5. Install the servo. Glue it with small dots of 5-minute epoxy or just tape it if the servo pocket is tight enough.
6. Finish the wing connector as usual. The free pin here is reserved for the in-wing antenna (72 Mgz), not needed for 2.4 radio.
7. Shorten the servo arm to the needed length. The hole must be just above the wing surface at full servo deflections. Carefully remove the masking tape.
8. Mark and cut the slot for the control horn directly downstream from the servo arm.
9. Fix the ailerons to the center of the wing with masking tape while installing the pushrods.
10. Glue the control horn into the slot with foam safe CA or epoxy. The horn must go all the way to the opposite skin and must be attached to both skins.
11. Prepare the pushrod with a Z-bend or a J-bend at the front end. Hold the pliers exactly at the control horn hole (actually a little forward to allow for the wire bend radius). Bend the wire - it must be exactly above the hole.
12. Cut off the wire leaving a few mm for the keeper. You can use a tiny piece of heat shrink tubing with CA to make a pushrod keeper. You are done with one pushrod. Repeat on the other side of the wing!
