Got a used Tarot 810 I am rebuilding. Any advice is welcome.

Hi everyone. About 4 months ago I got a Syma X5, then the X8G, a cheap racing 250 quadcopter, and then the Phantom 3 advanced. Now, I just bought a used Tarot 810 Hexacopter I am going to rebuild. I wish I got into this years ago. I have always been into photography and video, and when you add these two hobbies to high altitude shooting.... Wow! Anyway, check out the progress of the build if you like.
