Did you try to rebind the transmitter and receiver?

I tried but there is no signal been sent to the reciever

Did you connect the Max8 properly to the receiver? Just to be sure the receiver has power.

Does the screen mentioned 4.07 volt? That seems low.

The receiver has the red light on showing it is blinded to the sender but there is no signal to the receiver and after confirming the 4s battery is connected it starts flashing red also the Bluetooth programming unit has power red light on but does not give a Bluetooth signal to my phone its so frustrating i used it las in October last year and haven’t touched it til now just changing the esc .

Maybe the receiver died, alway good to have a spare or another car with the same receiver.
Did you connect the receiver to a different esc?

Yes same problem red light is on but does not get signal from hand set I think that there is only one way communication but I don’t know hw yo i plugged it back into the esc i was using last time i ran it but it’s exactly the same . All i can say about fly sky is cheap Chinese poop .but i only have one hand so im very limited to the controllers i can use one handed in my right hand the only on i have that works . There is no signal being transmitted from the controller
