They state, that this one should be able to take some hits before it breaks, actually, that it is nearly indestructible. This in fact is not true, it holds up far better than the original frame, but is still not up to par with something like the BetaFPV frame.
New batches of the Mobula7 will come with this improved frame by default.
The frame comes in two colors: Transparent or Transparent Black. It weighs in at 4.2g, so it is even lighter than the original frame that weight 4.8g.
Buy it from banggood.
