Since I am never happy with something the way it is when I buy it, I decided to do some modifications. My Phantom 2 Vision Plus always had a little vibration issue from day one. I swapped out props with no luck. Checked balancing and still a small vibration. I had 4 extra DJI 2212 920kv red motors which are basically the same as what comes with the phantom, so I decided to install them. I also installed the Graupner 9-5 E-Props. The result... Buttery Smooth!!!! Oh.. And battery life... I am getting about 1 minute more flight time. This mod doesn't cost much, but made a huge difference with my Phantom! Plus it looks cool!
