Surely there's a service center somewhere in Europe. Maybe try Ripmax in the UK?

The North American service center for Futaba cannot perform warranty service upon those items sold outside of North America, nor can we service radio equipment that is not FCC type accepted. Here's the list of international Futaba distributors:

Hi
You can change the sensor, it takes 5 minutes.
I had a problem with the sensor cabel, so i've just changed the sensor.

For what it's worth...

Futaba will tell you not to do that. They say the control box and sensor are calibrated together.

This is from the manual, page 4:
http://downloads.hobbico.com/softwa...912_CGY750_V1.4(E)_print.pdf
Gyro sensor replacement:
• Each CGY750 gyro control box is calibrated specifically for
the gyro sensor included. Do not attempt to use another
CGY750 sensor with the control box as performance will suffer
due to being out of calibration. The calibration process
must be completed by an authorized service center.
If your sensor needs replacement, please send the complete
unit to your region’s support center for repair.
I have no piratical experience with changing just the sensor so I'm not going to say it can't be done. You have obviously found you can successfully change just the sensor - sometimes. Just know that Futaba says they are a matched pair...

During manufacture and assembly of the CGY750 Gyro Sensor the following 6 parameters are detemined for that particular sensor.

When you bought the CGY750 in the box should be a card with the 6 parameters for that sensor. The FUTABA service centre closest to you should be able to confirm whether those values are in fact programmed in to your controller and correct it if nessasary (provided you include the card with your repair).

There are 6 alignment parameters in Degrees.
1. RA: Roll axis (aileron) offset to the yaw axis (rudder)
2. EA: Roll axis (aileron) offset to the pitch (elevator)
3. RE: Pitch axis (elevator) offset to the yaw axis (rudder)
4. AE: Pitch axis (elevator) offset to the roll axis (aileron)
5. AR: Yaw axis (rudder) offset to the roll axis (aileron)
6. ER: Yaw axis (rudder) offset to the pitch axis (elevator)

This data is saved to the controller and will be paired by 0.1 degree accuracy.

Sample Label Values below

The alignment offset data is pre measured at the factory and the values are written on a label as shown below which is contained in the sensor package.
Sensor Alignment Table
RA -0.4 d EA -0.4 d
RE +2.4 d AE +0.0 d
AR -0.4 d ER -0.1 d

When you get a replacement sensor the above Factory values should come with it, and should be programmed to the Control Unit.

Hope it helps

It occurs to me to ask...

What makes you think the sensor is malfunctioning? Do I understand you correctly - you believe the sensor was defective new from the box?

I have mailed in countless Futaba gyros after extended use at the field and been told they are out of calibration but I've never heard of a gyro being defective from new. I suppose anything is possible.

Can I ask, what problem are you experiencing?
