Phantom 3 Camera Guard, wide and slim version
The camera protection for DJI phantom 3 prof. is clamped in the landing gear and can be additionally secured with cable ties.
The length it is reinforced with 2 thicker bars.
I used thin structures to avoid too much air resistance and weight (14 gr).
In my tests, it was never in the field of vision of the camera.
Hope it could help you avoiding expensive repair. Enjoy!
Due to some comments regarding down camera and ultrasonic sensor I added a slim version. There is probably no area for a guard bar effecting none of the cameras and sensors. The Video Position System functionality may still be reduced. If somebody could test this, please post the result as a comment. Thanks
