Info

To set up your new MK EASY Okto V3 all you need is a screwdriver.
Solderings are not required. All components can be bolted and / or plugged.

Please read this page before you start to assemble your copter
This is an electronic flight instrument. A careful and accurate building assures you a flawless function and much joy with your new MikroKopter.

The Basicset includes GFK Centerplates. The CFK Centerplate shown in some pictures can be ordered as an option (Link).

Step1 - The arms

The riggers are mounted in the pre-assembled centerplate.

What is needed:

• 1x arm 460mm - red with LED
• 3x arm 460mm - black
• 2x arm 355mm - black with LED
• 2x arm 355mm - black
• 16x screw M3x16 (metall)
• 12x self locking nut M3 (metall)
• 4x dampener M3x15
• 12x screw M3x16 black (plastic)
• 12x nut M3 black (plastic)

On "Image1" you can see how to mount the single arms into the Centerplate.
The writing of the centerplate and the motors are pointing upwards.
Please pay attention to the arrangement and lengths of the booms (siehe Bild 1).

On "Image2" you see the 2 mounting holes you use on all arms. Fix them with 2 metal screws.

Important:
Insert the metal screws from the bottom of the Centerplate.

At the top you fix the screws with a self locking nut (Image 3).

Only on the 4 points where you see the circle on the top, you use a dampener (Image 4).

Please take care that you will not hurt or cut the cables.

At the edge of Center Plate, the arms can be fixed with 2 plastic screws and nuts.

Use only in 4 places instead of the plastic screw a metal screw (without nut). And this from top to bottom (see right picture).
Here we mount the LiPo-holder later.

If all is assembled it look like this:

Step2 - OktoXL V3 Combi PCB

Now we can install the OktoXL V3 Combi PCB.

What is needed:

• 8x screws M3x8 black (plastic)
• 1x cable tie

The LiPo cable is guided through the recess between the arms 5+6 und 6+7.

After the LiPo cables are properly laid, you can fix the PCB with the 8 plastic screws.

Important:
The arrow of the PCB is pointing to the red arm #1.

If this is done, fix the LiPo cabels with the bigger cable tie on the frame.

Important:
As you can see in the pictures, the LiPo cable must be twisted.
This prevents compass error!

Connect the PCB

In the next step we can connect the motors, the LED's and the buzzer with the PCB.

Important: Take a look on the pictures in which direction the plugs are connected.

Motor 1-8

The direction of rotation of each motor is determined by the plug-in order of the three cables.
On the PCB you will find a note for each color you have to plug in.

This is for the motors:

• 1,3,5,7 => A=gray, B=blue, C=black (left turning Propeller)

• 2,4,6,8 => A=blue, B=gray, C=black (right turning Propeller)

(Declaration of propeller rotation direction: see "Step7 - Propeller".)

TIP:
If the turning direction is wrong, change only 2 of the 3 cables.

Lighting

Connect the LED cables in the right way.

A wrong connected LED will not work.

The front LED strip is switchable !
This indicates e.g. the battery warning.

For this purpose, the gray cable from the Combi PCB is later connected to the switching output "L" of the FlightCtrl V3.0.
The two rear LED connections are supplied with 12V.

Buzzer

You can also plug the buzzer. Also here take care about the direction. If it is inserted incorrectly, there will be no signaling via the buzzer.

Step3 - FlightCtrl and GPS

Now the FlightCtrl can be installed.

What is needed:

• 4x spacers M3x10 black (plastic)
• 4x spacers M3x15 black (plastic)
• 1x Molexkabel 5pol
• 1x Tiny Servo Adapter
• 4x nut M3 black (plastic)

Install a plastic spacers M3x15 on each dampener (see Image 1).

On this spacers we mount the FlightCtrl.
Then fix the FlightCtrl with a plastic spacers M3x10 (see Image 2).

Important: The arrow of the FlightCtrl is pointing to the red arm #1.

Connect the Combi PCB with the FlightCtrl via the 5pol molex cable.
The gray cable of the OktoXL V3 Combi PCB is connected to the switching output "L" of the FlightCtrl.
With this output we can switch the front LED.

Connect the Tiny Servo Adapter with SERVO on your FlightCtrl (here you can connect later a camera gimbal).
(see Image 3).

The two receiver cables of the FlightCtrl and also the cable from the "Tiny Servo Adapter" are inserted through the outer recess between booms 5 + 6 downwards.
(see Image 4).

Now you can plug the two molex cables of the MKGPS V3.5 into the FlightCtrl. Her use "GPS" and "Compass".

If this is done you can mount the GPS and fix it with 4 plastic nuts.

Step4 - LiPo-holder

The LiPo holder is mounted under the copter. Max. 2x 6S/4500mAh LiPos fit into the already assembled LiPo holder.

We fix the LiPo holder with the 4 metal screws on the bottom of the Centerplate.
Please note that the opening of the LiPo holder points to arm #7..

Step5 - Hood

To save the electronic we use a hood. Install the hood on the copter that the 2 holes are pointing to the left and right side of the copter.
Fix the hood with 2 tapping screws on each side.

Step6 - Landing gear

The MikroKopter will get now a safe state with the landing gear HiLander26. For this we assemble a HiLander26 on each short arm (2,4,6 and 8).

What is needed:

• 4x HiLander26

Step7 - Propeller

In the last step we mount the propellers. Please note the direction of rotation.
The left turning propellers we mount on the large arms 1, 3, 5 and 7,
and the right turning propellers on the short arms 2, 4, 6 and 8.

Here you see how to fix the propeller:

After everything has been assembled, the finished MikroKopter looks like this:

Congratulations. The assembly of your OctoXL is finished.

Initial startup

After your MikroKopter has been properly assembled, it must be set.
