The great evil holly bush at the corner reached out and batted my Phantom Vision 2 plus out of the sky.. In doing so, it broke my prop guards and one of my props. I have an extra set of props so I was back in the air in a few. I went online and purchased more stock props. The model number on them is 9443 but when I went to DJI's store, they have one the is "thrust boosted" with a model number of 9450?? Anyone have a comparison of the 2? I am thinking of cutting the holly bush off at the ground and stockpiling props. Might need a recommendation on a chainsaw as well.
