So I got my new Walkera g2-d installed and again I experiencing pretty bad vibrations. My cheap chinese gimbal vibrated too, and I added a piece of innertube under the gopro and used rubber bands to secure it better, and it helped quite a bit. But still, sometimes almost ruined parts of video because of the vibrations would continue. The vibrations only happen when rolling forward to the max, so basically when the drone is doing 15-30 mph. Wind appears to make it worse. When rolling backward very fast vibration happens less. It vibrates with both stock p1 8 inch props and p2 9443s. I did a bit of reading on the forum and I saw one member that talked about his shell being cracked near the motor mounts, and that could cause vibration. My shell does have a crack on the front right motor mount. I've read that this is no big deal, and I plan on gorilla gluing it or something, and using a sewing needle to get deep in the crack. But I don't know if this could be causing the vibrations. It does appear to be slowly getting worse. I'm not sure if my props are balanced. I'll be getting a balancer here soon. It's driving me nuts, and it's highly disappointing. I'll be uploading a video to youtube here in a second to show you the vibrations.
