Sounds like maybe you have some binding in the tail or the control rod to the tail. Try popping the ball link off at the tail servo and move the control rod forward and back. Everything should move very freely with no binding anywhere.

How are you setting the gain?

Maybe the problem lies in the transmitter. What kind of Tx are you using?

I am using a DX6I with the stock reciever for the blade 400.
I checked the controls for binding, everything was good.

I plugged in a new servo to the gyro and it seemed to work, so I plugged my original servo back in and it started working.
I zip tied all my wired and the servo stopped working. If I thiump the gyro with my finger I can see the servo jump around like
it is trying to work.
I found a friends esky gyro and plugged it in, and it seems to work and function with the servo great. I am wondering how I
could have burnt up two gyros within minutes.
I am also using a common sense 45a esc. Do you think it can be giving to much voltage to the reciever and the gyro cant
handle it?

So you were saying that the 2 servo was burnt ? i would suspect bindings at this time make sure that the servos are not being obstructed and they can move freely, also check your gyro connections and settings it might be reversed some of the few things i can think of right now.

I tried re-binding, that didnt fix anything. No obstructions anywhere.
The servos work correctly except the gyro wont head lock it. Like if you rock the helicopter back and forth, the gyro will correct for it by moving the servo, it doesnt do that.
I tried a third gyro a little while ago and it seemed to work, so maybe I burt up two gyros.
I just can for the life of me figure out why that happened and if it will happen again. I could only assume I am getting to much voltage to the gyro and burning them up.
I will keep tinkering and see what I come up with.

you say it worked till you tidied the wiring up, may be it's a brake in the wire or a lose plug? it might even be a brake in side the servo,if you have a volt meter you could check to see if you ESC is under 6 volts, but I doubt it's that, chance of having two broken giro's is quite small if there is no under lying course,
one thing worth a check is the head speed or pitch at a hover, if it's to much you might run out of counter force, i.e. not enough tail,
it would be well over the norm of 6 degree's, more like 12 to have that affect but it can happen, just unplug the motor and hold the throttle where it normally hovers on the stick and check the pitch. your know as soon as you put the gauge on, or belt slip can do the same,so the belt is worth a quick check.
I've had servo's that seem fine on the ground but play up in the air, I don't know why, I just put it down to them reaching the end of there life,
If your buying a new servo I found the hitec 5084mg a good up grade from a 5065mg on my 450 and it's just a few $ more, it's a tad bit larger but not much and for the speed is well worth it,
