MAIN GYRO PAGE



THE GYRO TRUNCATES THE LAST 40% OF MY STICK MOVEMENT
The addition of a gyro onto the control surface of an airplane will affect the control throws.  The affect is often manifested in that you may set your dual rates into your transmitter but the settings do not have any affect as you inspect the expected changes on the ground.  Many gyros in rate mode will reach full difflection at between 40%-60% input from your transmitter when the gyro is not rotating (when you have it on the ground sittings still).  This is normal and expected. These gyros will change the aileron difflectlection in the air (less than you see on the ground) basd on the stick input, the gyro gain (rate mode) and the roll rate of the plane at the time. Since the maximum difflection the gyro can move the servo is based on the dial on the gyro (if it has one), the Travel adjust (endpoint adjust or ATV on some radios) adjust the rotation rate the gyro CONTROLS while active.

What I recommend you do is the following
1) Set the Travel adjust (endpoint/ATV) to 100%
2) Set a Dual Rate setting so you can switch from 100% and 50%
3) Set the limit dial on your Gyro (if equipped) so that you get the maximum difflection you want (or can have without binding). If possible,  adjust the linkages mechanically if your dial is above 110 or below 90
4) Set the gain to 30% rate mode
5) Test the sytem
6) Go fly it.
7) After flying, adjust the dual rates or Travel adjust to increase or decrease rotation rate in the air.

WHAT ABOUT IF I WANT TO USE THE OFF MODE (low rate gain)
But how does this affect me in the OFF condition? Well, there's where we have a bit of a problem. In the air, the control surface stick movement will be truncated like you see it on the ground. Negating basically the 2nd half of your stick movement.  If you have a gyro that is exhibing the behavior I'm discussing and you want to use it, the best way is to fly it always on rate mode.  Use OFF as an emergency condition. However, some may find that for the rudder, OFF is fine for most of the flying and your not really needing that much resolution out of it.  Another way you can handle it if your Radio permits it is to have a dual rate setting that is high (125% for example) for normal flying. Set your travel adjust to around 60%. Thus when you turn it off you can flip your dual rate switch.  Your going to have to experiment here in any case.
