NX3 Evo Flight Controller System Manual
VERY IMPORTANT!
Please release or turn off the emergency switch when the plane become level
flight and under control. Emergency mode just for emergency situations.
Please use good quality BEC or ESC as power supply. Do not use Ni-Mh and
dry cell batteries.
When use NX3evo in Delta wing or V-tail plane, please turn off mixers on your
transmitter, and set the DIP switch on NX3evo.
For the first flying, it’s better to keep a lower sensitivity (-20%~+20% gain,
10~14 o’clock is recommend) and then increase it gradually.
Check every axis gain direction befor flight.
When you triggle the emergency switch, The elevator will move up and then
move down slowly. If it is not, please reset this function refer step 4.8 radio
stick direction calibration.
Must keep the plane level and stable when power on the system.
When switching on the radio control system it is essential to keep the
transmitter aerial at least 15 cm away from the receiver aerials at all times.
Otherwise,NX3evo will read the wrong center position of receiver signal .
The Controller has to re-learn center position after installation,or replacing a
new radio system, or making a trimming(or Sub-Trim)change within the
transmitter, otherwise the servos may move to one side automatically.To do
this,just quickly flip the flight mode switch twice within 1 second!

4. Installation:
WARNING: PLEASE READ THE FOLLOWING STEPS VERY
CAREFULLY BEFORE YOU START TO INSTALL A NEW PLANE!
Step 1:Configure the plane without NX3evo.
Create a new model in your transmitter. Do not engage any mixer on your
transmitter.Assign two switchs for NX3evo.One is for AUX(flight mode change),two
or three steps. Another is for Emergency(Rebound Toggle Switch is better).Make
sure all servos moves smoothly.
Step 2: mount
NX3evo need to be
firmly mounted near
the gravity center of
the plane with
provided
double-tape . Please make sure the long side of NX3evo is in line with
the fuselage. And the logo side should face up. After mounting, please check again
whether the board is firmly attached to the aircraft.
Step 3: DIP configure
1. If you are a beginner, please turn the switch (T) to the right.
2. If you want yaw attitude locking, please turn the switch (Y) to the right.
3. For delta-wing plane, please turn the switch (D) to the right.
4. For v-tail plane, please turn the switch (V) to the right.
Step 4: Wiring
Connect NX3evo and the receiver using wires in the package according the following
figure.
Step 5: AUX Channel or Master Gain channel Setting
NX3evo use AUX channel to change flight mode.The travel of AUX channel also
controll the Master Gain of NX3evo.Decrease the AUX travel will decrease all three
axises correction. NX3evo will be in Beginner Level or Expert Level if AUX channel
do not connect to the receiver.
Step 6:Individual Correction Gain and Correct Direction Configuration
Using the provided screwdriver to adjust the gain
pots on NX3evo board control the correctional gain
(sensitivity) and correct direction for the following
controls: pitch (ELE), roll (AIL) and yaw (RUD)
axis. You'd better start with a lower sensitivity for
your first flight (-20%~+20% gain was recommend)
and then increase it gradually. The aircraft will
become vibrative if the gain is too large.
Before configure the Correct Direction, please switch to Practicing Level or
Promotion Level at first, power on the system, pick up the airplane and check it by
following the three steps below:
AILERON Quickly move the right wing upward around the roll axis, the right
aileron will flap up and the left flap down.

ELEVATOR Quickly move the tail upward around the pitch axis, the elevator will
flap up as shown.
RUDDER Quickly move the tail to the right around the yaw axis, the rudder will
turn to the right as shown.
Step 7: Emergency Mode (must connect the emergency cable) configuration
The emergency mode need an assigned switch in your transmitter (Rebound
Toggle Switch is better).Toggle the switch to activate the emergency
function(switich channel signal 100).When you release or turn off the emergency
switch(switich channel signal less than 100),NX3evo will return to the previous
flight mode.When Emergency Mode activeated, the plane will flying level and up
rapidly for about 3 seconds.If you do not release or turn off the emergency
switch ,the plane keep roll levelling and pitch climbbing flying attitude.
Step 8: Radio Stick Direction Calibration
When active emergency mode, the ELE will flap up and return original level slowly. If
it is not, you must calibrate the direction of your radio stick follow the steps below.
1. Please refer the picture on the right: move the switch ‘D’ & ‘V’ on
the right side, and switch’T’&’Y’ on the left side.
2. Power on the radio and NX3evo, wait patient until NX3evo LED
flashing slowly. Then move the two stick to the lower left corner
and hold this position until the LED turns off. That means the
calibration is done.
3. Re-set the DIP refor to 4.3.
5.Dual Aileron Setting
NX3evo support single aileron signal and dual aileron signal.If the Aileron R IN
cable be attached to the receiver ,Dual Aileron function will active automatively.
NX3evo also support Y-cable function if the Aileron R IN cable not be connected to
the receiver.
NOTE: if Dual Aileron function activated, please don’t use the beginner mode
simultaneously.
6. Re-learn center position
The Controller has to re-learn center position after installation,or replacing a new
radio system, or making a trimming(or Sub-Trim)change within the transmitter,
otherwise the servos may move to one side automatically.To do this,just quickly flip
the flight mode switch twice within 1 second!
7. Flight mode details:
1. Beginner mode
feature: Aileron auto-leavel . roll angle limit to ±75 degree.
When the aileron stick back to center position, the aileron will keep level
automatically.
The elevator will be control by youself, there is no auto-level function. But will
provide obvious assist,the pictch have attitude locking function.
Beginner mode is for very beginner player.Also can be used for short-range FPV.
2. Practice mode
feature: attitude locking for roll,pitch,yaw.restriction on roll and pitch speed.
Practice mode do not have auto-level and angle limit function.
Practice mode is for practise flying.
If you want yaw attitude locking, please refer 4.3 DIP configure.
3. Promotion mode
feature: attitude locking for roll,pitch,yaw.
Promotion mode is very likely from practice mode.It provide aititude locking
function.Compare to practice mode,promotion mode supply more sensitive
sense of control .
If you want yaw attitude locking, please refer 4.3 DIP configure.
4. Expert mode
feature: simple Gyro correction.The best control sense.
It supply a simple Gyro correction and anti-wind function.
5. Emergency mode
feature: Roll auto-level,climb up.
You can triggle the emergency switch in beginner mode,practice mode,promotion
mode and expert mode to activeate emergency mode.In emergency mode,airecraft
will keep roll level and then climb up by a small degree.
