FLIGHT TESTING

Time spent fight testing and setting up the gyro will ensure optimal performance from the plane. Because aircraft vary in weight, size, control response, and a host of other factors, you’ll need to program unique settings. Here are some tips that apply to all gyros.

Allow the gyro to initialize after turning on the plane, per the manufacturer’s instruction. The gyro may not function if the plane is moved or disturbed during the initialization process.

At the field, double-check the control-surface direction as you normally would (with the gyro off). Turn on the gyro and verify that it is functioning properly and giving the correct commands when the aircraft is rotated about the various axes.

Periodically check that the gyro is still securely mounted to the airframe. A loose gyro will cause havoc in the air.

Perform the initial takeoff with the gyro off, if it has that capability. Once at a comfortable altitude, switch it on and be ready to turn it off at the first sign of trouble.

Fine-tuning the gyro gain may require numerous flights. The gain can be thought of as the degree of response to a disturbance. A low gain setting results in little dampening, while a high gain results in a rapid response. If the gyro gain is set too low, the gyro will not be utilized to its fullest potential with little dampening. If the gain is set too high, the plane will oscillate or hunt. Start with a low gain setting and test-fly the plane. If there is no oscillation, turn up the gain slightly and perform another test flight. Repeat this process until oscillation is experienced. Back off the gain and verify that there is no more oscillation. Depending on your personal preference, you may want to further fine-tune the gain setting.
