I need help.... My DJI phantom 2 vision (with aftermarket gimbal -- Cyclops Vision Brushless Gimbal for Phantom Vision [AF-CVG]) has got a very shaky camera. I noticed this phenomenon shortly after the quad had crashed into a building (sorry, no footage of that). I found it upside down and beeping like it had one of the motors disconnected. However, that was not the case. In an effort to try to fix the shaking, I replaced all four stock motors with Emax MT2213-935KV brushless (2xCW, 2xCCW). I Balanced all of my propellers and have done my best to balance the motors using a seismographic app for my iPhone (and instructions from YouTube). I have included a short video: If anyone has any ideas on how I might fix this, I welcome them!
