5.  Gyro installation

◆ 

the gyro should be installed in a vertical or horizontal alignment on a stable platform, as far as possible away 

from the engine and other electronic devices. 

◆ 

the gyro should be installed using double-sided foam adhesive between the gyro bottom and gyro mount. To 

prevent transferring fuselage vibration to the gyro, make sure the cables are not pulled too tight and that the 
case does not touch any other helicopter component.

 when installed in small electric helicopters, use a 2mm or 3mm foam double-sided adhesive pad.

◆ 

when installed in a large helicopter or when there is helicopter vibration, it is recommended to use a metal 

plate between two foam double-sided adhesive pads.
