1.4 Prepare Wolf QAV250
The assembly of Wolf QAV250 has already been completed when leaving the factory. You only need to install the propellers according to the instructions before flying. If the aircraft is left unused for a long time, it is strongly advisable to uninstall the propellers with the professional tool packed in the set and to (dis)charge the batteries to best storage status, that is, 3.8V per cell to avoid unexpected damage and to extend the product life span.
1.5 Prepare Transmitter
Wolf QAV250 PNP version is not equipped with a transmitter. You can optionally purchase a RadioLink transmitter to control Wolf QAV250, such as AT9S Pro.
If RadioLink transmitter is not equipped, please first install the receiver on the aircraft and bind your own transmitter and receiver after receiving Wolf QAV250. The detailed transmitter settings and radio calibration in Mission Planner depend on your transmitter, which will not be explained in detail in this manual.
Take AT9S Pro as an example. Before starting the flight, we need to power on the transmitter first to ensure that the transmitter works properly. AT9S Pro works with Lithium 2S-4S battery or 8 pieces AA battery. To avoid batteries over discharged, alarm of low voltage can be set after connecting batteries in the transmitter. Press “MODE”to enter the BASIC MENU => Select “PARAMETER”and enter=> Set“TX-ALARM”according to the actual battery used. For example, if batteries used in the transmitter is 2S, then it’s 4.2V*2S=8.4V when fully charged. As the voltage of a single cell is 3.7V, we usually set the low voltage alarm as 3.7V*2S=7.4V.
Chapter 2 Aircraft Setup
Wolf QAV250 consists of flight controller system, remote controller system, GPS system, power system, and image transmission system. This chapter is about the aircraft’s components and the feature of each function.
2.1 Setup for RTF and FPV Wolf QAV250
RadioLink Wolf QAV250 has 6 versions. (Please refer to Chapter 1.2)
If you have bought the version with RadioLink transmitter, you only need to power on the transmitter and the aircraft, and then arm the aircraft for flight.
2.1.1 Basic Operation of the Transmitter
As the aircraft is controlled to realize all movements by operating the remote controller, it’s important to know its basic operation.
Remote controller is also called transmitter and should work with a receiver. Transmitter in a pilot’s hand and receiver in an aircraft to work as the flight controller system.
The 4 basic channels of all transmitters are always the same:
Channel (CH) |
Movement |
Channel 1 |
Roll (Control aircraft to move left/right horizontally) |
Channel 2 |
Pitch (Control aircraft to move forward/backward) |
Channel 3 |
Throttle (Control aircraft to lift and descend vertically) |
Channel 4 |
Rudder (Control aircraft to turn clockwise and anticlockwise) |
These four basic channels are operated by the two sticks on the transmitter. Most transmitters have not only these 4 channels but also other auxiliary channels such as switches for changing fight modes, controlling PTZ and camera. These commands will be passed to the receiver on aircraft via wireless signal by the emission system of transmitter. So we usually name the channels besides 4 basic ones auxiliary channels.
Here is a picture of transmitters with stick mode 2 (left throttle). Take RadioLink AT9S Pro transmitter as an example
For Wolf QAV250 that comes with AT9S Pro, auxiliary channel mapping has already been set on AT9S Pro. The specific mapping table is as follows:

2.1.2 Arm and Disarm Wolf QAV250
Arm: Channel 6 of the transmitter is assigned to control motor lock by default. If RadioLink transmitter is not equipped, please assign a two-way switch for channel 6. If AT9S Pro transmitter is equipped with Wolf QAV250, you can unlock/lock the motor with SWA switch. Push SWA up. If the indicator light of the flight controller is solid blue or green (Solid blue means the flight controller has been unlocked, but GPS positioning has not been performed; solid green means the flight control has been unlocked, and the GPS has been Positioning), and the motor and propellers start to spin slowly, the motor is unlocked.
Note:
Please ensure that the SWD is in the low position by default. If SWD is in the high position, it will automatically enter the RTL mode, which will result in the inability to arm.
When GPS positioning is not available, if the flight mode is Pos-Hold mode or loiter mode, which rely on GPS positioning, the arming will fail.
Please connect 6S lipo batteries to Wolf QAV250. Otherwise, the flight controller will issue a low-voltage alarm and fail to arm.
If the SWA is pushed up before the flight control self-test is completed, the aircraft will not be unlocked, but the motor lock will be removed. At this time, the flight controller indicator flashes blue. You can push SWA down and push it up again to unlock the motor.
Push SWA up. If the indicator light of the flight controller flashes yellow, there is some errors when arming. Please connect the flight controller to Mission Planner and make corrections according to the error prompts.
For more details, please refer to the detailed manual of CrossRace Pro: https://www.radiolink.com/crossracepro_manual
Disarm: Push down SWA, the motors and propellers will stop rotating immediately, and the flight controller indicator will turn yellow and flash, which means the motors are locked. This locking method can be used for emergency locking. In the event of an emergency, pushing down SWA can force the motor to stop rotating. If the aircraft is in the air, please use this function with caution to avoid property damage.
2.1.3 Flight Modes Introduction
Wolf QAV250 has five flight modes by default: Stabilize Mode, Alt-Hold Mode, Pos-Hold Mode, Manual mode and RTL Mode.
In Chapter 2.1.1 Basic Operation of the Transmitter, the functions of auxiliary channels were mentioned. One of those is to switch the flight mode.
For AT9S Pro, the 3-way switch (SWC on the right) by default, UP is Stabilize Mode, MID is Alt-Hold Mode, DWN is Pos-Hold Mode. Push SWB from down to up to enable Manual Mode. Push SWD from down to up to enable RTL Mode. For more flight modes, please refer to the manual of CrossRace Pro:
https://www.radiolink.com/crossracepro_manual
Note: The flight mode of the aircraft always remains the last selected flight mode. If you push SWB up first and then SWD, the aircraft is in RTL mode; If you push SWD up first and then SWB, the aircraft is in manual mode.
RTL Mode Enabled:
Besides manually enabled by pilots (SWD of AT9S Pro), RTL Mode of Wolf QAV250 can be automatically activated under the below two situations:
Signals lost.
Low voltage. Wolf QAV250 comes with a 6S lithium battery. RTL mode is enabled when the battery voltage is lower than 21V by default. You can modify it according to your own usage habits and flight plan. When the voltage is lower than 21V after a period of flight, the aircraft will automatically rise up to a certain height (15m by default) and then land on the point that it takes off. By the moment, Wolf QAV250 won’t move even if pilots toggle the transmitter sticks. Please arm the aircraft once landed and disconnect the battery and get it charged. If you need to operate the aircraft during the RTL process, you only need to switch the flight mode to another mode and then switch back to the original mode to exit the RTL mode.
After the aircraft returns to the take-off point, it will perform a landing operation. At this time, the pilot can fine-tune the position of the aircraft as needed to ensure that the aircraft lands at a suitable location.
2.1.4 Manual Mode of Wolf QAV250
Push SWB up to enable manual mode of Wolf QAV250. In this mode, the angle and speed restrictions of the flight controller will be completely released, and the flight attitude will be completely controlled manually. The aircraft will not automatically return to center after the joystick is returned to center in manual mode. Note: Pilots without manual mode flight experience are advised not to use this mode! In manual mode, the maximum flight speed can reach 180+km/h, please pay attention to flight safety.
2.2 PNP Version Setup
After receiving PNP version, the parameters of the aircraft have been set at the factory. PNP version does not come with a transmitter, so the pilot needs to set the transmitter.
Pilots who purchase PNP version of Wolf QAV250 need to: install Mission Planner to work with the flight controller, bind the transmitter and receiver and get the parameters set, and install the propellers.
Note: Wolf QAV250 PNP version is also compatible with the transmitter and receiver of the other brands. But please make sure that the receiver is SBUS/PPM/CRSF supported. When using a CRSF protocol receiver, please connect the receiver to TELEM1 or TELEM2 of CrossRace Pro. Please see Chapter 5.2.3 of the CrossRace Pro manual for details: https://www.radiolink.com/crossracepro_manual
2.2.1 Bind Transmitter to Wolf QAV250
Every transmitter owns a unique ID code. Before using, binding transmitter to receiver on aircraft is a must. When done binding, ID code will be stored in the receiver, no need to rebind.
If your transmitter has done binding with receiver, you only need to connect the receiver to the CrossRace Pro flight controller after receiving the PNP version of Wolf QAV250.
Connect RadioLink R12DSM receiver to CrossRace Pro
Binding the transmitter to the receiver is essential. Otherwise, the aircraft cannot take off.
Binding steps of all RadioLink transmitters and receivers are the same as follow:
Put the transmitter and the receiver together within 50 centimeters.
Power on the transmitter and the receiver. The receiver will bind to the closest transmitter.
Press the ID SET(binding button) on the side of the receiver for more than 1 second, the flashing LED means binding starts.
When LED stops flashing, binding is complete. A signal tower appears at the top of the home page of the AT9S Pro indicates successful binding. If there is no signal tower, please repeat the above binding steps.
When binding is done, please check if the receiver change to SBUS/PPM output . Generally we use SBUS signal. LED on all receivers from RadioLink is blue/purple means SBUS signal while red means PWM or PPM signal. Pilots can short press the binding button to switch the signals output of the receiver. For more details, please refer to the manual of RadioLink receivers (R12DSM manual: www.radiolink.com/r12dsm_manual). If receivers from other brands are used, please refer to their manuals.
2.2.2 Installation of Mission Planner
Before setting flight parameters, please install the Mission Planner for parameter adjustment of CrossRace Pro.
To run the Mission Planner installation, NET. Framework from Microsoft is needed. Link is as below

2.2.3 Transmitter Parameters Setup
The flight controller of Wolf QAV250 has been set with all necessary parameters by default. For the PNP version, please calibrate the radio, set the flight modes and Fail Safe.
2.2.3.1 Radio Calibration
Before the radio calibration in Mission Planner, please make sure the model type selected in transmitter is multi-rotors. Below detailed steps take RadioLink AT9S Pro as an example. For the calibration of the transmitters from other brands, please kindly refer to the its instruction manual.
Press“MODE”for more than 1 second to enter the BASIC MENU and choose“MODEL TYPE”, rotate the dial to select “MULTIROTOR”and press“PUSH”to save, then“END”to exit.
Note: For RadioLink transmitters, the throttle phase needs to be set REV. Throttle of AT9S Pro is set REV by default. Press“MODE”of AT9S Pro for 1 second to enter the BASIC MENU and choose“STEERING REVERSE”and select 3: THROTTLE. Then “PUSH”to select and rotate the dial to“REV”and“PUSH”to confirm then“END”to exit.
Make sure binding between the transmitter and the receiver is complete before connecting CrossRace Pro with Mission Planner on computer via USB cable with the Baud Rate of 115200. The connection between CrossRace Pro and Mission Planner can be also achieved by data transmission with the Baud Rate of 57600. Then power on the transmitter.
Open Mission Planner => select the corresponding Baud rate and port => click to connect
Note: Ports varies from different computers. Please select the correct port to connect. Connection may fail with several ports in use. Please remove the other connections, or enter Device Manager to view the port of CrossRace Pro, just as below:
.
Click INITIAL SETUP =>MANDATORY HARDWARE => RADIO CALIBRATION =>CALIBRATE RADIO
There are two tool pop-ups after you click “OK”, one for make sure both your transmitter and receiver are powered on and connected, and the motor of your drone does not have power and without propellers.
And then click“OK”and move all RC sticks and switches to their extreme positions so the red bars hit the limits.
Joysticks can be calibrated as following , both (CH1 to CH4) are pushed to the limits(up/down/left/right)
If the red bars have not any change when you move the sticks, please check the receiver have connect success or not, make sure the receiver (maybe R9DS) is output SBUS signal (the blue LED of R9DS means work as SBUS signal). You can check if every corresponding red bar for every channel is work as below:
CH1: low position = roll (towards the left), up position= roll (towards the right).
CH2: low position =pitch(forward), up position =pitch(backwards).
CH3: low position =reduced speed, up position =speed up.
CH4: low position = yaw (towards the left), up position = yaw (towards the right).
2.2.3.2 Flight Modes Setup
Set flight modes in the transmitter (refer to the following steps for RadioLink transmitters. When using transmitters from other brands, select channel 5 to set flight modes, and select the SBUS signal for the receiver. The settings of the flight controller in Mission Planner is the same as the following steps). QAV250 also uses channel 6 and channel 7 as two special flight mode selections. Please check the channel mapping table for more details.
CrossRace Pro has many flight modes, and you usually choose six. If the six are not enough, you can also add the assistance of CH7 and CH8, up to eight flight modes. But Wolf QAV250 is with five flight modes as factory setting by default including Stabilize Mode, Alt-Hold Mode, Pos-Hold Mode, Manual Mode and RTL Mode (See picture below). Therefore, if no other flight modes needed, pilots just set the flight modes in transmitter corresponding to those in flight controller.
Flight modes setting steps(Take AT9S Pro as an example):
1. Connect CrossRace Pro and receiver (connect the RC port of CrossRace Pro, and make sure receiver work as SBUS signal).
2. Make sure transmitter bind to receiver successfully.
3. Make sure CrossRace Pro connect to Mission Planner success and click INITIAL SETUP—Mandatory Hardware—Flight modes, you can setup the flight modes you want in this menu.
In flight modes menu, it’s very clear that the flight modes, the PWM numerical interval of six flight modes you have set and choose Simple Mode/Super Simple Mode or not.
Most of the RC fans setup the Flight Mode 1 is Stabilize, the other five flight mode will be setup according to users’ flight habit.
First, you have to setup flight mode in transmitter. The setting steps as below:
1. Power on and turn on your transmitter.
2. Press Mode button twice to into ADVANCE MENU, press Push button into ATTITUDE setting menu, CH5 is default to the attitude control channel and please choose a 3 Posi-SW and a 2 Posi-SW to control the attitude. (For the flight mode settings of CH7 and CH8, open Mission Planner--- configuration/debugging
---extended parameters---Channel 7 opt/Channel 8 opt, and then assign 2 control switches for the two channels in the transmitter. ) The attitude settings on AT9S Pro are as following:
3.Setup Flight Mode 1 is Stabilize both in Mission Planner and transmitter.
Make sure the -swt- is ON (by press the 3 Posi-SW or 2 Posi-SW to make it ON or OFF) and then you can setup the PWM data.
Setup the PWM value according to the default numerical interval (change the value by turn the dial, press the Push button when you choose the right value.)
4. Mode 4 needs a two-way switch. Turn the switch to the corresponding mode. Set it in the same way as step 3.
5. When using other transmitters to set flight modes, please first set the mixing control of channel 5. Mix a two-way switch and a three-way to channel 5, and set the value range according to the following chart:
Flight mode |
Value range(us) |
Flight mode 1 |
0-1230 |
Flight mode 2 |
1231-1360 |
Flight mode 3 |
1361-1490 |
Flight mode 4 |
1491-1620 |
Flight mode 5 |
1621-1749 |
Flight mode 6 |
1749+ |
For example, Wolf QAV250 has 3 flight modes by factory default. A three-way switch is assigned to control Channel 5. In Stabilize mode, We set the value range to 987 for Stabilize mode, between 0-1230, so Stabilize mode is flight mode 1; The value range is 1500 for Alt-Hold mode, between 1491-1620, so Alt-Hold mode is flight mode 4; The value range is 2000 for Pos-Hold mode, flight mode 6. Manual mode and RTL mode are activated by separate switches. Please check the channel mapping table for details. The order of flight modes can be modified according to your own flying habits.

2.2.3.3 Failsafe Setup
CrossRace Pro supports Return-To-Launch in cases where contact between the Pilot’s RC transmitter and the flight controller’s receiver is lost. This page explains this failsafe’s setup and testing. Note the“Radio failsafe”was previously called “Throttle failsafe” because of the way in which some receivers use the throttle channel to signal the loss of contact. Make sure the connection between the transmitter and receiver is successful and the receiver supports SBUS signal.
F/S setting steps:
Receiver and flight controller CrossRace Pro setup:
By default, a newly purchased receiver will be set-up to simply hold all channels at their last known position when the receiver and transmitter lose contact. This is not good because the flight controller has no way to know that the Pilot has lost control of the vehicle. Instead the receiver must be set-up to signal to the flight controller it has lost contact and there are two ways that it can do this (the method depends upon the receiver):
“Low-Throttle”method - the receiver pulls the throttle channel (normally channel 3) to a value below the bottom of its normal range (normally below 975).
With the LiPo battery disconnected:
1. Connect your flight controller to the mission planner and select Initial Setup >> Mandatory Hardware >> Failsafe.
2. Set the Failsafe Options to one of the three options:
(1) “Enabled always RTL” to force the vehicle to always RTL even if flying a mission in AUTO mode.
(2) “Enabled Continue with Mission in AUTO” to allow the vehicle to continue with missions even if it takes the vehicle outside of RC range (not recommended). In all other cases the vehicle will RTL.
(3) “Enable always LAND” to force the vehicle to Land immediately if it loses RC contact.
Set the “FS PWM” value to be:
(1) at least 10 PWM higher than your Channel 3’s PWM value when the throttle stick is fully down and the transmitter is off.
(2) at least 10 lower than your channel 3’s PWM value when the throttle stick is fully down and the transmitter is on.
(3) above 910.
Click OK to into the failsafe setting menu.
You can turn off transmitter to check if the Failsafe setup success(the PWM of CH3 is smaller than 975)
If enabled and set-up correctly the radio Failsafe will trigger if:
(1) The pilot turns off the RC transmitter.
(2) The vehicle travels outside of RC range.
(3) The receiver loses power (unlikely).
(4) The wires connecting the receiver to the flight controller are broken (unlikely).
1. Set battery fail safe
Set battery fail safe according to the aircraft power consumption, battery voltage, and flight distance. When the battery voltage is lower than this value, there will be enough battery voltage to return the aircraft. Set the low battery value (This value is set according to the battery voltage. When you fly long distances, Please set the single cell to 3.8V, the voltage value is 3.8V*S, the 6S battery is 3.8*6=22.8V; when at a close distance, you can set 3.6V for each cell), and set the action to RTL (return to home). RTL mode is enabled when the battery voltage is lower than 21V by default. You can modify it according to your needs.
The battery monitor has been calibrated at the factory. If the voltage measurement is inaccurate, please follow the steps below to re-calibrate it.
2. Set the radio fail safe (throttle fail safe). Set the action to RTL , and set the fail safe PWM (generally no need to change). Set the fail-safe setting in the transmitter, because we set the fail safe to start after the throttle is lower than 975, so we need to set the throttle fail safe value. Push the throttle trim button in the transmitter and check the input value of channel 3 in the transmitter in fail safe, so that the value is less than 10 or more than 975. Take RadioLink AT9S Pro as an example. Press the Mode button to enter the basic menu and select FAIL SAFE. Press Push to select Channel 3: Throttle. Turn the dial to select F/S and press Push button. When a value appears, the setting is successful. Remember to turn trim button to restore.
When a radio Failsafe is triggered one of the following will happen:
Nothing if the vehicle is already disarmed.
Motors will be immediately disarmed if the vehicle is landed OR in stabilize or acro mode and the pilot’s throttle is at zero.
Return-to-Launch (RTL) if the vehicle has a GPS lock and is more than 2 meters from the home position.
LAND if the vehicle has no GPS lock OR is within 2 meters of home OR the FS_THR_ENABLE parameter is set to “Enabled Always Land”
Continue the task if in automatic mode and the failsafe option is Enabled_continue_in_auto_mode.
If the failsafe is cleared (the throttle is above 975), the aircraft will continue to fly in the flight mode corresponding to the previously set failsafe, and will not automatically return to the previous flight mode of normal flight.
For example: the RTL mode is set for the fail safe, and the aircraft is flying normally in stabilize mode. Suddenly the fail safe is triggered due to signal loss, causing the aircraft's flight mode to automatically change from the stabilize mode to the previously set RTL mode. Even if the transmitter and receiver signals are reconnected during the return journey and the fail safe is released, the aircraft will still fly in the RTL mode. If you need to fly in stabilize mode again, you need to move the flight mode switch to another position and then back to the position of stabilize mode.
Set attitude fail safe in the transmitter. The prerequisite for setting attitude fail safe is that there is a fail safe mode in the flight mode settings. Taking RadioLink AT9S Pro as an example. Turn on the transmitter, flip the setting switch to RTL mode or the fail-safe mode you want to set, press Mode to enter the basic menu, select fail-safe, press Push to select 5: Attitude, Toggle to select F/S, hold Push, and the numbers below will change. Open Mission Planner to verify it. Turn off the transmitter and check that it is RTL in Mission Planner.
2.2.4 Propellers Installation
Wolf QAV250 PNP version is NO propellers installed for the package reason. So when the above steps are done setting(parameters set, ESC calibrated, arm successfully after powering on), propellers are ready to be installed. Make sure the correct installation of each positive/counter propeller. otherwise the aircraft may fail to take off.
As the image shown below, put the head with camera forward when installing propellers and make sure propellers on Motor 2 and 3 rotate counter clockwise while that on Motor 1 and 4 rotate clockwise.
Note: Never install the propellers before finishing setting parameters of aircraft to ensure the safety.
Wolf QAV250 is equipped with RadioLink MINI GPS TS100 as factory setting. If the Pos-Hold Mode and RTL Mode needed, please go to an open space and wait till the satellites searched to enjoy the flight.
Green indicator on GPS TS100 flashes means satellites searched. It’s advised to wait some time (about 1.5-2 minutes) for searching satellites at the first flight. And it will be a bit longer in cloudy weather. The quantity of the satellites searched reaches 18 or above will ensure the pos-hold and RTL accuracy.

Chapter 3 Flight
3.1 Visual Flight
At the beginning, it’s advised to flight visually by practicing basic movements like flying forward/backward/
leftward/rightward and hovering.
For example, beginners can try hovering under the stabilize mode by toggling the joysticks to adjust the aircraft to remain the same position. Then the horizontal 8 training for the next step.
3.2 FPV Flight
Different from visual flight, FPV is first person view with the help of a goggle or a screen. Theoretically, FPV flight is easier than visual flight because pilots can clearly judge the moment to turn or forward with goggle or screen.
Note: The image transmission, goggles and FPV monitors included in the FPV versions of Wolf QAV250 have already been linked by factory default and can be used directly without the need to link again.
