Configuring the Radio Transmitter
During the configuration of the radio transmitter, the default option is that the GCS of the CC3D disables the unlocking of the throttle. You'd better check whether the throttle is locked before configuration to avoid any damage during the configuration caused by having forgot to unload the battery. Click Transmitter Setup Wizard to enter the interface of configuring the radio transmitter.
You can also click Finish and choose another way to configure the radio transmitter like clicking Configuration->Input->Start Transmitter Setup Wizard as shown below.
Pay attention to the points below before configuration:
1) Keep the receiver correctly connected to the flight controller which is powered by a battery. If not, follow steps in 2. Connect the receiver to connect.
2) Switch on the radio transmitter; make sure your transmitter works well with the receiver, and they can be paired.
After entering the interface of configuring the radio transmitter, follow the prompt on the screen to pull the rockers. You can cancel or return to the last step at any time during the configuration.
Next, choose the type of transmitter of the radio transmitter between Acro and Multicopter. Acro is suitable for fixed wing aircraft and quadcopter. Therefore, here choose Acro.
Next, select the transmitter mode of the radio transmitter. Here are two options: throttle-left mode and throttle-right mode. The default one is the throttle-left mode namely Mode 2 as below: Throttle and Rudder on the left, Elevator and Aileron on the right.
Click Next, follow the prompts on the screen to calibrate the throttle, aileron, elevator, and rudder respectively.
Firstly: When you move the throttle stick for the first time, if it is moved all the time even when you move other channel sticks, you should follow these steps to check.
1) Check whether the receiver is correctly connected to the CC3D board. Pay attention to the wire order and not to inversely connect the wires.
2) Check whether the power supply of the CC3D is turned on. Only the USB port for CC3D is not enough to power the receiver.
3) Check whether the receiver and the transmitter are matched successfully. Press and hold the button on the receiver until the LED onside blinks, and then the LED will brighten constantly, indicating the receiver is matched successfully.
4) Check the receiver’s mode. You need to be aware of the color of the LED on the receiver for each mode. Press the button twice quickly to shift modes.
If after you move one stick of Throttle, Pitch, Roll, and Yaw, the stick on OpenPilot still moves, it means the corresponding channel has not been configured well. Then click Back, and repeat the previous steps to check.
Then, calibrate the flight mode. A 3-way auxiliary channel would be better to set. Note down the aux channel for flight mode setting, since we will use it later.
Configure Accessory 0, Accessory 1 and Accessory 2. If you don’t want to do that, just click Next/Skip.
After all the configuration, keep all the channel switched at neutral. Click Next.
Please move all controls to their maximum on both directions to check whether all channels have been configured well. You should see the stick in OpenPilot moves as the real stick does. If not, please click Back to configure that channel again.
Based on the instructions, pull the throttle, aileron, elevator, or rudder or toggle the mode switch to check whether it moves in the same direction as the stick actually does.
For example, when you move the Throttle stick from lowest to highest on the transmitter, if the throttle stick on the OpenPilot also moves in the same way, it’s OK; but if it move from highest to lowest, it's got reversed. Then just tick the Throttle in the software and there is no need to configure it on the radio transmitter.
Until now, all the configuration of the channels is completed. Click Save and then enter the configuration of unlocking the radio transmitter.
During configuration of the radio transmitter, by default the throttle is locked. You can define the method to unlock it in the way you like. Next, set the time of receiving no signal to automatically lock the throttle. 30s is set by default. Usually, we unlock the throttle through Throttle off (to the lowest) and Yaw Right.
Finally, Click Save.
