This is a manual for building the CNC Head assembly for the Walkera DF59/60 Heli.
Items needed for this build
2 x 1.5 hex wrench
2.0 hex wrench
Precision Screw driver Set
CA ( Loctite )
non silicone Grease
Loctite RED/Green
Main Rotor Blade Grip Assembly
Dis-assemble blade grips using 2 x 1.5 Allen wrench
( Blade grip, Hex Screw , Washer, inner bearing, outer bearing, tapered
washer, Rubber O-ring, feathering shaft. Head holder)
Clean all parts with alcohol and assemble back in the correct manner
Add a thin film of non silicone grease on the feathering shaft and the rubber O-ring
Insert the rotor head Pin on the Main Rotor head assembly
Screw back The main rotor head cap make sure to add loctite on the screw thread before screwing in the cap
Screw back the red Lock ring on the Rotor head pin. Dont forget to put some red Loctite on the thread.
Push the feathering shaft thru the rubber O-ring. Make sure the shaft is filmed with a thin coat of grease to prevent damage on the rubber O ring
Add some loctite on the hex screw before screwing in thru the feathering shaft
Using 2 x 1.5 allen wrench tighten the screw on both blade grips. Make sure that this is tight and packed to prevent play on the blade grips and possible popping out during use.
Walkera DF60 Head Assembly:
Unscrew all ball links on the head assembly and add red loctite on the threads. These are really not tightened when it arrives from the factory.
Clean all ball parts with alcohol and put some red loctite on the links thread then assemble back in the Ball Links grips.
The Ball links included with this Head are all one way links, Note this links only go to the ball one way. If you notice the hole on the links have different diameter. The larger side hole diameter must be facing the ball when snapping. Doing it the other way around will damage the plastic link and may come loose during flights. In adjusting the links make sure to make one full turn 360° since the links cannot be plugged it at 180° no half turn allowed.
Main Shaft assembly:
The new CNC head comes with a main shaft. The original DF60 main shaft will not fit the new head. There is a difference in the hole locations and length of the original shaft with the new shaft.
To install the new shaft remove the pin connecting the shaft with the main gear. Be very careful in removing the pin. Do not use too much force of hammering down the pin. Too much force will damage the one way bearing inside the red metal plate. Either use a vise to gently pop out the pin or just tap it lightly with a small philips screw driver with the same diameter as the pin. Once remove the shaft will slide out and can be replaced with the new shaft.
Walkera DF60 Head Assembly Settings:
The New DF60 CNC head differs from the Original head mixing, As the swashplate goes up the blade pitch is negative and as it goes down it becomes positive pitch. This is because the swashplate is directly liked to the blade grips unlike the original Walkera head this passes thru another mixing arm at the top located at the Flybar area.
Because of the different mixing there should also be a Fix on the Electronics on the WK 0701 TX dipswitches to accept new Swash plate collective mixing. Please follow this table below for the New Head to work on the New CNC head.
NOTE: The Aileron and Pitch servo must also be interchange on the RX this is the no 2 pin and no 6 pin. Just interchange the J pin location on the two servos and the mixing will now work correctly.
