C) Adjusting The Piezo Gyroscope - Reely SKY Dragonfly Pro Bedienungsanleitung

c) Adjusting the Piezo gyroscope

• The Piezo gyro's task is to ensure that the tail of the model always points into the right direction and is not pushed
to the side due to air swirls or gusts of wind.
• The gyro is switched between the receiver and a tail servo and has a Piezo element to help it detect rotations of the
helicopter around the vertical axis (rotor shaft) and counteract these via evaluation electronics.
• The gyro transmit direction changes initiated by the pilot to the tail servo.
• The gyro has various switches and controllers for adjustment, which were already set by the factory. However, you
can adapt these settings to your special wishes.
Operating and display elements of the Piezo gyro:
1 LED display
2 Delay regulator
3 Controller for the servo path limitation
4 Switch for changing the servo direction
5 Switch digital/standard servos
1. LED display
The LED display serves to display the different gyro statuses
• LED blinks fast: Initialisation and matching (performed right after activation).
• LED blinks slow: Missing servo signal from the receiver.
• LED is off during operation: Gyro works in normal mode.
• LED is lit during operation: Gyro works in AVCS mode.
• LED always blinks twice: The current neutral setting of the servo deviates from the saved neutral setting.
2. Delay regulator
The gyro is able to emit rapid correction control signals to the connected servo.
With slow analog servos, it may happen that the gyro controls faster than the servo can execute the control commands.
In this case, increase the signal delay. To do so, adjust the potentiometer with the help of the enclosed adjustment
screwdriver step by step to the right. When using a digital servo, the delay must be set to 0.
As an analog but very fast servo was installed for the tail function in the factory, you should also set the
delay to 0 with this servo.
