Hi,
Does anybody have an idea why a servo would not move? I plugged it in a different port and it works, just not the elev port, like its supposed to. It's a new set up and was working when I built the heli. I tried to adjust the gyro and now it just will not move. I even ordered a new servo and it's the same thing. Dx7 ar7000. Align 410m servo.

Could be a defective receiver. But more than likely, it's a setup issue.

Hell... I can fix that.
Uh oh..
Nope.
It's ***ked!!!

Just for fun, re-bind your receiver.

If that doesn't work, try a different model memory in the transmitter and re-bind.

Could be the radio is in a different mode (Mode 1, Mode 2)

Do ANY servos work when plugged into the elevator channel?

I suggested using a different model memory as a test. A new, unused model memory, or one that's been "reset" should not have any odd behavior.

I don't know what you could have done to the GYRO setup to cause the ELEVATOR channel to just stop working. The gyro controls work through either channel 5 or 7, and neither of those is the elevator.

Did you somehow dial the endpoints on the elevator channel to 0, or mix in some odd mix value that messes with the elevator?

If all else fails, reset the model you memory you're using then rebind. That should clear out any weird behavior.

I will try another servo in that channel. Good idea, I did'nt think of that! I did however reset the dx7 and it did'nt help. Thanks for all the help. I'm a total newbie to programming.

You're not doing something just plain dumb and plugging the servo into the socket upside down, are you? It won't HURT anything if you do, but the servo just won't move.

Hey -- here's a thought. Go to your transmitter's MONITOR window -- the one that shows the stick movement...

Move the elevator stick and see if its corresponding monitor bar is moving with the stick. That should help you figure out if the TX is weird or the RX is toast.

I suppose you could also use one of the mix functions, and mix -- say aileron to elevator. That way, moving the AILERON stick which you know works, should move the servo plugged into the elevator socket.

This, in addition to the info in the MONITOR screen ought to help you figure out what's bad.

If you are using the servos on a ccpm heli check transmitter settings for 3 servo ccpm.also i have had two of those receivers that have both had faulty aileron outputs(bad soldering) which resulted in one servo not working.
