flight controller beeping and blinking constantly

[Alex2000]

I just replaced one of the esc's on my drone and now when i power on the drone, it constantly beeps and the flight controller is blinking red as well. If someone could help me figure this out it would be greatly appreciated.

Hi can you give the guys more info what quad is it ?
Is it the same make of ESC that it came with ?

Yeah the quad is a arris c250, and yes it is the same ESC that came with it. I got the beeping to stop by resetting the quad but now I’m having trouble pairing the flysky radio to the receiver.

Do your new ESCs have a BEC (5v output)? Did everything work before the ESCs had to be replaced?

Blinking red LED on your flight controller typically indicates that it's not getting a signal from the receiver.

What rx do you have.? It can be a bit tricky having only 2 hands
Normally you have to press the bind button on Tx then press the other button on rx & apply the power. The tx will then confirm it is bound.
If you want help with Aux switches, just ask.

I did have an i6 but recently got the evolution.but both basically the same.
