ESky Alloy Head Assembly:

How to assemble the ESky CNC alloy head for King and Belt-CP.

Parts required:
1. Main Blade Clamps
2. Alloy Rotor Head
3. Alloy Swash Plate
4. Alloy Washout Assembly
1. Firstly, you'll need a philips screwdriver and 1.5mm allen driver. Also, thread lock and CA glue for use where neccesary.

   2. In addition to the alloy components you will need the control linkages from your original rotor head. Its best to work on a clean, clear surface.
 
3. Insert the flybar holder through the head and attach with the 2 silver screws. Use thread lock on these. Ensure the screw hole is on the right side.

   4. Screw and slide one of the alloy levers along your flybar. The length between paddle and lever should be about 56-59mm with the paddle fully screwed in.
 
5. Push the flybar through the flybar holder, attach the other lever and paddle. Centralise everything and tighten - ensuring the levers are level with the paddles.

   6. Assemble the components of the pitch levers...
 
7. and attach them to the flybar holder in the direction shown here.

   8. Assemble the bearings and washers as shown here, with the smaller holed washer on the inside.

 
9. The collared washer should have its raised edge towards the bearing. The spacer shim washer should be left out if the blade clamps don't move freely once tightened.

  10. Insert the rubber o-rings and slide the shaft holder into the head.

 
11. Pop the plastic linkages onto the levers and insert the shaft through shaft holder. Attach the second blade clamp and tighten both shaft end screws.

   12. The head is fixed to the main shaft with a pin and grub screw.
 
13. Insert the pin here, and fit the grub screw using thread lock.

   14. Slide the washout assembly up the main shaft and onto the two locating pins.
Connect the battery  
15. Slide the swashplate up the shaft and attach to the plastic washout linkages.

   16. Finally connect the control linkages to the head, as shown in these pictures.

When installing onto the heli; note it is important that all the parts are free and do not bind. If this is the case, loosen where needed, making sure thread lock is re-applied to secure the metal to metal bolts and screws. If they bind, this will cause battery drain and possible damage to the servos. I would recommend building the head onto a new main shaft - removing the old shaft and head for use as a guide of direction and alignment.

Also note: you will have to re-setup the blade pitch once the installation is complete.
