Frame Assembly
On each page of this manual the parts required for each
step will be listed below along with a set of images showing
the stages of each part of the build.
When you see this symbol apply a little threadlock to
the end of the screw before assembly. When reassembling
make sure you clean off any old threadlock from any parts.
Note: When putting the canopy mounts together make sure
you have them protruding from opposite sides of the frame
as per image 2 below. The screws in image 5 only need to be
finger tight at this stage, We will tighten them properly once we
add the boom in a later step.

Frame Assembly Continued
This step will add the lower frames, the tail gears & bearing block.
There looks to be a lot to do in this section but both sides are
identical.
It will probably be easier to follow the smaller images below as
they show fewer items and the best order in which to put them
together.
Note: When adding the lower frames, screws and spacers for
images 4 & 5 it is best to put them all in finger tight resting the
model on something flat to make sure the frames are parallel
and then removing one screw at a time add threadlock and
screw in tight.

Frame Assembly Continued
This is the last part of the frame assembly adding the rest of the
screws, the Battery mounting plate, Base plate, Servo Mounts &
Main Shaft bearing block.
Again there looks to be a lot to do in this step.
It will be easier to follow the smaller images below as
they show fewer items and the best order in which to put them
together.
Note: All Screws on this page will need threadlock, the threadlock
symbol has not been placed by each screw as the image is already
quite complex.

Skids Assembly, Battery Plate & Swash Restraint
Now we will add the skids assembly and the last parts that go
on to the frames.
This section is quite straight forward, Should any problems occur
the images below should help.
Note: The black ends on the skid pipes are shown connected on
the image these will need CA.
To glue the rubber stoppers on the skids slide them past the place
where they need to sit then add the glue to the skid pipe before
sliding in to place to avoid getting ca all over the pipes.
Add CA Glue where you see this symbol

Tail Assembly
This step starts the tail assembly adding the tail hub, belt, boom
and tail shaft.
This section is quite straight forward, Should any problems occur
the images below should help.
Note: Add CA to the tail shaft then slide on the tail gear before
assembly

Tail Pitch Slider
This step will add the tail pitch slider.
The only part that may cause a small problem in this section
may be the plastic pitch arm, it does require a small amount
of force to get it on to the pitch slider hub. Image 1 below shows
the angle to slide the arm on to the hub before snapping in place.
Note: Do not over tighten the screws in images 2 & 4 so that the
pitch slider and ball link arms move freely, if they are a little stiff
back the screws off slightly. When adding threadlock to the screw
in image 4 it may be better to add it to the mount so not to get
threadlock in the bearings.

Tail Blade holders and Blades
This is the penultimate section in completing the tail assembly.
Note: When adding the threadlock to the 2 blade holder screws
it will probably be better to add it to the blade hub so not to get
threadlock in the bearings. You will need 2 screwdrivers when
tightening the 2 blade holder screws, using 1 will just cause the
screws to turn in the bearings. Do not overtighten as the blade
holders need to move freely and it may crush the inner races of
the bearings. Do not overtighten the blade screws (image 5) the
blades need to be secure but able to move in there holders when
a small amount of force is applied

Tail assembly completion
This step will complete the tail assembly adding the Horizontal,
Vertical fins tail control rod and boom mounted tail servo holders.
Note: Do not add threadlock to the servo holder screws (image 5)
untill you come to add the tail servo so you can get the correct
placement. The screws in image 4 need only be finger tight untill
we add the boom struts in the next section in order to slide the
horizontal fin into place.

Attaching the Tail assembly to the frames
Note: Before inserting the tail section into the rear of the frames
the tail belt needs to be rotated 90 degrees anti clockwise, do not
twist more than 90 degrees as this will cause the tail to grind or lock
up when turning the main blades. The screws in the boom hub
may need to be loosened slightly before inserting the boom, once
the boom has been inserted and the belt placed over the gear the
boom can be pulled backward to apply tension to the belt then the
hub screws can be tightened. When squeezing the belt together
between the boom hub and tail gear both sides of the belt should
not touch each other but stop about 3 quarters of the way.

Rotorhead Assembly
This is the first step in asembling the rotorhead be sure to double
check the amount of washers needed for each section.
The images below show the best order in which to put the head
together.
Note: Do not overtighten the screws in image 2 and 6, the flybar
rocker and washout arms should move freely.

Flybar carrier and head button
This step will add the flybar carrier, flybar and blades to the main
rotorhead hub.
Note: Before threadlocking the 2 grub screws (image 4 ) make sure
the flybar is centered and there is the same distance from either end
to the flybar carrier arms, once centered tighten one grub screw to
hold the flybar in place then threadlock the other grub screw tighten
then remove threadlock and tighten the first grub screw.

Main Blade Holders
Now we will add the main blade holders on to the rotorhead.
It is easier to build one side of the blade holders first, push 2 o-rings
on to the feathering shaft then the washer then the smaller bearing.
Then place the feathering shaft assembly in to 1 of the blade
holders, place the larger bearing and small brass washer on to the
screw and isert into the blade holder screwing in to the feathering
shaft. Pass the feathering shaft through the blade hub and
complete the opposite side.
Note: When adding threadlock it will be better to add it to the end
of the feathering shaft to avoid getting threadlock in the bearings.
Be sure to check the orientation of the blade holders the side with
the ball link on should face the trailing edge side of the blade.

Washout Assembly.
In this step we will add the washout assembly.
As per image 1 below build the 2 washout arms first makeing sure
the ball link goes on the inside of the arm with the centre standoff
sticking out away fromo the ball link.
Note: As with any moveing parts you do not want to over tighten
the screws in images 2 & 3 below to allow smooth movement but
you also do not want any play in the parts. When pulling on the
washout arms there should be no lateral movement but they
should rotate freely. Also note the way the 2 black washout arms
face inwardsas per image 4.

Swashplate Assembly
Screw all 4 ball links on to the upper part of the swashplate.
Screw only 2 ball links on to the lower part of the swashplate
leaving one arm with no ball link. Th 3rd arm will have a longer ball
link that will go through the swash restraint in the next step.
Note: Add threadlock to all the screws with the ball links making
sure not to get any on the rotating parts of the swashplate. There
are 3 links to add in this section 2 long 1 small. There lengths are
as per the dimensions on the right.

Adding the rotorhead and Main gear to the frames.
Add the main gear assembly with the one way bearing in to the
frames when lowering the rotorhead in to place.
Note: There is not much to note in this section other than the bolt
in image 3 will go through the gear assembly through the main shaft
then out the otherside of the gears.

Main Blades
This is the last step of the build adding the main blades completing
the model.
Note: The 2 nylock nuts are locking nuts so will not need any
threadlock. The main blades should be tight in the blade holders
but should be moveable when a small amount of force is apllied.
