I had an accident yesterday with my Phantom2. A USA Flag knock down my Phantom, now i got a broken 3D Gimbal and broken Gopro Hero3, but i got the shot. Watch the video here. https://www.youtube.com/watch?v=-UY9Spi ... e=youtu.be My 3D gimbal is gone and needs to be replace. My Gopro Hero 3 + Black is still working, just the lens glass broke off. See attach picture. I need to replace the Gopro Stock lens. Any ideas? Comments or suggestions. I saw some options but i don't want to spend $100+ for a lens. I am looking for a 4mm decent lens for under $100.
