Wild thumper trex controller wifi receiver problem!

Recently, I have bought a wild thumper 6wd with a trex controller to make a robot. I started to use it with a EZC-RC wifi receiver.

I used the 4 wire with the trex controller to connect the receiver. After connecting the receiver and turnig the controller on (using the dagu high power switch) I hear 3 beeps mean that it enters the RC mode. I can control the robot with the android app comes with wifi receiver and every thing is fine. But after some minutes playing with it, specially if I change dirction (forward & backward) quickly, receiver stops working and I loose the wifi connection (it is not displayed anymore in wifi connection list).

For connections, I have used 16AWG wires which are I think strong enough. I
am using a 6000maH 2s batteries:

and I am using the code comes with trex board (not made any changes).


I don't know what is the reason. Noise of the motors or power problems. I have put the reciever far from the board, but it is placed above the first row motors.

Any help will be appreciated!

Thanks a lot!

maybe battery voltage dips?

what power source are you using?
