Hi there.
It is likely that the ESC or the little box that sits between your receiver box and servos/motor has gone belly up. This device controls not only motor speed but the action of any servos connected to it. Essentially it interprets the signal it gets from the transmitter and turns it into physical movement of the servos. If this device has died, or is damaged, those interpretations will not be correct or accurate. I would look at trying to replace this part first.
Hi, well form what you describe, it would seem as though you have had some sort of, after, the receiver failure, in particular the servo driving discriminator, has failed, (Quite common).
There is no real "Fix" the only way to remedy this issue is by replacing the receiver in it's entirety :(
Well that's unless you have a surface mount rework station and access to the IC's, & semiconductors, that need replacing? In that case it's a simple fix? not.
Please inspect the balancing needle at the top. Bring this into its original position. This will balance the helicopter. Then it will work fine again.

that doesnt seem to do anything to help at all
That doesnt seem to fit with my problem, i will re write and hope that will to be more of an explanation to you.Model MD 500 hughes co axial helicopter from Blitz rc works.
I was flying the helicopter when it just droped from a hover with a high pitched noise and the lcd light on the top was blinking rapidly. I disconnected the power and then reconnected it and with that the two servos went into full lock and the whining returned. There is no drive from the motors and there is no resonse from the transmitter. It just sits and whines at me. I try tried re binding the the transmitter and receiver but that wasnt done anything. The lcd light on the PCB flashes red and green then goes to a constant red light.
Not that much of a help lol noticed the advert says a 3 ch model is actually a 4 ch heli but never the less still stuck and grounded. So your saying i have to change the receiver unit then ?? Bloody Banana Hobby they wont even reply to the mails sent them. Thanks for your suggestions though.
