New firmware V184.108.40.206 update; H3-3D latest firmware: V220.127.116.11 • Quick start guide and user manual will be updated, for more information please visit www.dji.com Firmware update: The firmware optimized the H3-3D gimbal Yaw axis tracking (or follow), the gimbal Yaw axis will move as well when you turn the Phantom. This greatly reduces the probability of capturing the Phantom landing skid. 2. Securing kits mounting guidance a. We recommend mounting the securing pins and washers to the diagonal locations shown below. This will prevent YAW axis blocking during flight. b. Insert the securing washers to the first clamp ring slightly, if you over tighten, it will stop at the second clamp ring. This will affect damping. 3. Add a standard accessory: anti-interference reinforcement board. If you have any suggestions or questions, please contact us at firstname.lastname@example.org, thanks!
