Er staat wat over geschreven in de The Electric Helicopter Beginner's Guide, denk dat dit wel de info is die je zoekt Citaat:
#Most gyros (GY240/GY401) require mounting on a horizontal surface, but some gyros (Ikarus Profi, CSM LW200, GWS PG-03) require mounting on a vertical surface. Be sure to check your gyro's documentation to see how it should be mounted on your heli!
#Make sure your gyro is mounted firmly to the frame and/or to a gyro mount which is firmly attached to the frame. Be sure to use the manufacturer-supplied double-sided foam tape or equivalent to attach the gyro to the frame or gyro mount. The double-sided foam absorbs high-frequency vibration which will cause a heading hold gyro to drift, so the tape is VERY important. DO NOT USE VELCRO to mount the gyro! Do not put a nylon tiewrap, velcro wrap, or other strap around the gyro and frame. This strap will transmit vibrations from the frame to the gyro case. Also, the strap will compress the mounting foam, which will prevent the foam from absorbing vibration.
If a heading hold gyro is not FIRMLY mounted, then this problem will cause tail wag. This will occur because the gyro will be wobbling and will not sense the correct angular position, and will overshoot when trying to return the tail to the "correct" position.

Bij mijn x400 zit de gyro ook standaard bovenop de staart, maar ik heb deze verplaatst binnen het frame, toch wat veiliger
