After some time of flying I have found and learned ways the E-sky 4 channel 0404 transmitter can be adjusted . I don't remember the instructions saying anything about that :
1. The length og the control sticks can be adjusted. See the second picture below. Loosen the control stick and turn the small screw inside the stick until it has the desirable length and fasten the stick again.
2. The resistance in the control sticks can be adjusted. Open the transmitter by unscrewing the four screws on the back of the transmitter. See picture below. After opening the resistance in the sticks can be adjusted by adjusting the three screws shown in the last picture.
The three leftmost circes are for the resistance force in the control sticks.
3. The thrust ticks can be removed. Loosen the screw shown in the rightmost circle in the last picture and turn the metal piece going into ticks away.
Feel free to comment with more possible adjustments
