NSTRUCTION
Thank you for purchasing a G190 gyro, a rate gyro for small electric powered helicopters. G190 is a
small and light-weight gyro with high-performance, employing small size piezoelectric sensor of little
temperature drift. In addition, the G190 unit is well deigned as any side of its case can be used for easy
and stable mounting.
Features of G190
Small piezoelectric sensor
G190, utilizing a small piezoelectric sensor of little temperature drift, has achieved a very stable
performance.
Small, light-weight and all-in-one
Our high-density assembly technology has made it possible for G190 to become very small
(22.2x22.8x8.9mm, excluding protrutions) and light-weight (6.7g).
Newly designed case capable of using any side of the case for mounting
The newly designed case, any side of which can be used for mounting, is very small and highly
flexible for being correctly positioned and correctly oriented on the limited space of a small-size
electric powered helicopter. Consequently G190 can maximize its gyro performance.
Applicable to the micro servo S3108
Combination of G190 and S3108 micro servo would further reduce the total weight.

Set Contents
The G190 comes with the following accessories:
G190
Double-sided tape
(3 sheets)
Functions and Connections
LED monitor
Rudder input connector
Connects to the receiver rudder
channel output connector.
Rudder servo connector
Connects the rudder servo.
LED monitor:
• Quick Blinking: The LED continues blinking quickly as the initialization of the G190 au-
tomatically starts immediately after the power is turned on.
• Always On: As soon as the initialization is completed, the LED turns on continuously
and G190 is ready for operation.
• Slow Blinking (about 1Hz): If the G190 receives any abnormal signal from the receiver,
the LED starts slow blinking.
