Its not needed at all in your case. Only good when travelling because that would mean a harsh treatment at the airport etc.. In your case the. Phantom is secured and it wont fall around in your car. Zenmuse h3-3D for example never had such shippings locks. When you have a case and always level it and handle it with care you dont need it. I never used such a clamp in 3 years. Using the foam will probably stress the gimbal more than without with the constant on and off procedureDo u guys put the gimble guard back on when you transport your drone?
I have a case and only go from house to car and back. No heavy traveling
