Hey, got some questions about my gy401/9253/9CHP.

1. ~50% throw on the rudder gives me 100% throw on on the servo. My rudder ATVs are 100%. Neither adjusting this or the limit setting on the gyro seems to fix this. How do I get get full throw on the stick to equal full throw on the servo?

2. The instructions say that a a steady flashing light indicates ACVS mode. If I turn on the gyro while the radio is in ACVS mode, the light come on solid, no flashing (after the initial setup flashing). Otherwise it seems to work ok. Is this normal.

3. If I turn on the gyro while the radio is in normal mode, the light gives me a steady flash, and doesn't change when I switch to ACVS mode. I assume this has something to do the the gyro needing to be started in ACVS mode. So what do I do if I want to fly with the gyro in normal mode and have the radio in normal mode (no idle ups), becuase the 9CHP errors is I'm not is normal mode when it turns on?

Not sure about the first part of your question but on the gyro you must always turn on your RAdio in AVCS mode. Once the gyro finds center then you can go ahead a switch it to normal.

If you boot your gyro in normal mode it will give you a blinking red this tells you to shut down and reboot in AVCS.When you boot your gyro up in AVCS mode you will get a steady red light until you give a rudder command then it will go off then back on when the servo returnes to center .

In the 9c to set the gy 401 gyro you don't use gyro sens mixing. that must be inh. U use instead the end point adjustment. You set the sensibility of the gyro as a normal servo rate (channel 5). Channel five is related to a 2position switch so when It's up you set the avcs mode when you flip it down you set the normal mode.
Then you turn on the radio in avcs and after you just flip the switch.
If you would like the switch to operate in the poosite direction (IE avcs down, normal up) you just reverse channel 5 like it is a servo
