A few months ago i bought a DX 3.0 for my electric cars.I noticed that often i lose my cars control.Without a reason,communication between transmiter-receiver stops for some seconds and the car is uncontrolable,without steering,throttle or brakes.This happens with both receivers i have for my two cars.I have to tell you that with other brands radios i don't have this problem and this is not caused by the distance as i remember that i noticed this issue on 5m ,on 25m or 50m.As you can understand is very risky to run my cars like this so im asking for some help.What can cause this issue and what can i do for this?
