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!
