Update: Just received and installed the upgraded arms. Definitely sturdier.
Will let you guys know on durability as I put more batteries through it.

Wanted to build a new quad with some extra parts I had laying around, Just needed a frame. Ran across the TBS Source V Race frame for under $30 so figured lets give it a shot. Could not find any instructions that were helpful, but managed to get through it after a little trial and error. After building and flying for first time, I fell in love with the way this thing handles. I think the saying is "on rails"
It could be a lot lighter if i had used different parts, but im not going to be racing, and the thing is plenty fast. Especially on 5s.
