Basic Functions

DDF-350 Basic Functions

Receiver Function

The transmitter and receiver have finished binding by default, If it is a newly bought receiver accessories, you need to refer to the following method of bind:

1. Put the transmitter and the receiver close to each other(about 60CM);
2. Turn on both the transmitter and the receiver;
3. Press the button for more than 3 second and release, the LED will flash quickly, indicating that the bingding is ongoing;
4. When the LED stops flashing and is always on, binding is complete. If not successful, the LED will keep flashing slowly to notify, and repeat the above steps.

Note: The close distance between the transmitter and receiver may cause a signal block, which leads to unsuccessful binding or signal loss.After the binding is successful, if the transmitter and receiver are too close, the signal may also be lost because of signal block. Bring the transmitter and receiver father apart, the signal loss will disappear automatically.

Display Instructions

Key type

The keys of ch3, ch4 and ch8-10 of the remote control can be set to locking signal or inching signal.

• Locking signal: press the key is on, and then press it is off;
• Inching signal: press the button is on, release is off.

Steering throttle brake curve

• Steering curve:This function is used to change the sensitivity of the steering servo around the neutral position.
• Throttle/brake curve:This function makes the throttle operation quicker or milder.

Gyro mixing control

• The gyroscope of the receiver is turned off by default, and the gyroscope function of the receiver can be turned on according to the instructions of each receiver.
• To adjust the gyroscope sensitivity through the transmitter, the gyroscope mixing control option of the transmitter needs to be enabled.
• We can choose to VR – 5, VR – 6 knob or NULL, choose NULL can manually enter a value directly to the current value.
• When we change the value of the adjustment knob, the number of the corresponding CH8 channel will change, the higher the value, the higher the sensitivity of the gyroscope, the ratio value is 0, the gyroscope has no enable.
• If you find it difficult to turn on and off the gyroscope sensitivity through the knob, you can use an enable switch. By setting an enable switch, it is easy to switch between the activation/deactivation of the gyroscope function by pressing a button.
