6. Einrichtung

6.1 Einlegen der Batterie

The MT12 controller uses 2 x 18650 cells or a 2S 7.4V 5000mAh battery pack. Ensure correct polarity when inserting batteries into the provided tray or connecting a LiPo pack.

6.2 Bindung des Empfängers

To establish communication between the MT12 controller and the R85C receiver, a binding process is required. Refer to the detailed steps in the included manual for your specific receiver type (R85C or ER3C-i).

For receivers with built-in gyro functionality, ensure the gyro is activated and configured correctly after binding. The sensitivity of the gyro can often be adjusted via a potentiometer on the receiver or through the controller's menu.

This video illustrates how to activate and configure the gyro function on a compatible receiver. It covers switching the receiver to gyro mode, checking the gyro phase, and adjusting sensitivity. While the video features a Radiolink receiver, the principles for gyro setup are generally applicable to the MT12's R85C or ER3C-i receivers.
