yup!,,,,I lost one of the motors e-clips, taking one apart to balance motor housing, any idea of where to get a set, Ebay has them for 450 but can't seem to find some for P330
I had one pop off, and when I tried to replace it it broke, I actually bought some that did the job from a local rc shop, but I found these while searching
I also bought a bearing kit on ebay and got them with in a week. I have not installed the bearing yet,but they look like they are good ones and they come with e-clips.
If you are going to do any kind of bering work, white lithium grease is your friend! I had an anti grav motor take a face plant into some beach sand. I cleaned it all out and used white lithium grease on the bearings. It worked like a charm!
