3. Installing Control Surfaces

We need to install the threaded inserts into the 2 short control surfaces and 2 long control surfaces for the Aft Cap

Heat set the threaded insert into each of the control surfaces using a soldering iron.

Cut the 4mm Stainless Rod to length. The length for the short control surfaces is 208mm

Cut another 4mm Stainless Rod for the long control surfaces at a length of 212mm

Optional: You can grind/file a flat onto the control rods to give a better surface for the set screw to screw into holding the control surface in the correct position.

Install 1 of the short control surfaces onto one end of the 208mm control rod.

Insert an M3 set screw into the threaded insert and screw it down onto the control rod to fix it in place.

Ensure the control rod is flush with the end of the control surface.

Slide the Control rod through the first hold of the Bottom Aft Cap.

Slide the 4mm Bevel gear onto the control rod.

Now align the 4mm bevel gear with the bevel gear on the servo and fix into place with the set screw on the 4mm bevel gear.

Once the control has been inserted fully into the Bottom Aft Cap. Install the second control surface and fix into place with an M3 Set Screw

Slide the 212m Control rod through the vertical hole of the Bottom Aft Cap.

Slide the 4mm Bevel gear onto the control rod.

Now align the 4mm bevel gear with the bevel gear on the servo and fix into place with the set screw on the 4mm bevel gear.

Don't install the second long control surface until you have fitted the top aft cap.
