My fairly new Phantom 2 Vision had something loose knocking about inside of it after my first flight. I wasn't sure what it was until I discovered one of the props was sticking a bit and the motor assembly could be lifted up a little. I took apart the housing and found that the e-clip that holds the bushing in place at the bottom of the motor spindle was lodged in a crevice and the bushing was missing. Is it possible to order a new bushing and e clip? I do not know of an RC parts store in my area that might have loose parts. Are there any after market bushings and bearings for the Phantom? This should be a cheap fix... if I could find the parts. Crickets from DJI when I emailed them. Or I could buy some upgrade motors from T-motor? Does anyone have experience with their Antigravity motors? Worth the extravagant price? Thanks!
