The manuals for the Hobby Eagle range of Gyros can be downloaded here:
IMPORTANT** When a gyro is powered on and the aircraft is on the ground, it is normal for your radio's throws/rates and expo to not visually appear to be working. This is because in flight, the gyro is mixing the appropriate amount of throw to correspond with your radio's preprogrammed throws/rates.
Also, when configuring any gyro, if too many changes are made to it in a row, and you detect that the gyro's behavior is not consistent with your inputs, we recommend resetting the gyro, by depressing the control button and continuing to hold it down while you plug in the battery. Follow the manual's instructions on how to reset your gyro.
