Gyro not initializing properly all the time
I have a JR 7000t gyro and lately it has not been initializing properly. On first start of the day it will start up and push tail blades all the way to one side; and not respond to stick inputs correctly on the bench. I then turn off electronics and try again and now it centers up fine and responds correctly. (some times takes two times.) I am then able to do a flight just fine; all works well in the air.

My questions
1. Does this mean the gyro is going bad? (it has lived thru a few crashes)

2. Is it ok to fly as long as I am able to get gyro to initialize properly.

I really dont want this thing to let loose when in the air.

I am not really familiar with the JR/Spec binding process,but I have seen a few posts where issues like this were solved by re-binding.Compass helis Support Team

+1 on re-binding.

Also wait for at least 5 seconds after switching on tx before you switch heli on.
60% of the time, it works every time!

If a Spektrum/JR radio, bind the radio with the gyro gain control switch set to the position you want it to be at power-up. This will guarantee that the RX outputs the proper signal to the gyro during initialization while the TX and RX link up.

If you are messing with rudder trim AFTER you let the gyro initialize, or if you have different rudder trim settings for different flight modes -- 1) stop fiddling with rudder trim AFTER the gyro initializes, or 2) make rudder trim in all flight modes identical.

Well I rebound the rx and it seems to have worked. Before gyro would not initialize properly half the time. Now after 10 bench test's it has not messed up once. Thanks for the help. Will do flight test when it stops raining.

During the period where the TX and RX are linking up, the RX needs to send out what the gyro expects to see when it is going through its initialization process. Binding the RX with the gyro control settings in the correct position will make sure that the RX sends those positions out before the TX and RX are fully sync'ed up. If you don't go through this particular step, the RX can send out information that in not what the gyro is looking for during, and after initialization.-----

The amount of time that is required for the Rx Tx connection varies quite a bit. The amount of time between power on and when the gyro tries to initialize is pretty constant. If the switch was in the wrong position at bind time, and if connect time is longer than gyro initialize time, you will have the problem. As you said, about 50% of the time.
