no rudder control mcpx

[dge]

I'm having rudder control issues with my mcpx. When I give it rudder it doesn't respond. It's an intermittent problem. It will fly just fine and then all of a sudden it won't respond to rudder controls.

I've checked connections, radio settings and everything else I can think of. I thought it might be a radio issue but I can fly my msrx and mqx without any issues. I'm just wondering if it's a tail motor but it doesn't really seem like it. they usually either work or don't work at all.

I did just change out the mainframe. But I don't think that's the problem. I'm afraid it might be board related. I was just wondering if anyone else has experienced this and might know what the cause is.

The only advice I have is to try rebinding the heli to your radio. Someone else may have other ideas. If that doesn't work then you may have a bad 3 in 1 board.
