Lobster, I have been having the same problem. The arms still seem to be too flexible even at %50 infil. I went nuts balancing my props, best balance job I have ever done in my humble opinion. And things got way better. I got it in the air and flyable but there is still some resonance and the whole quad will twitch randomly. So its back to the drawing board to beef the arms up a bit more. Compared to the first design the second gen arms work much better but there is still a was to go hopefully arms 3.0 will be the ticket. Also I am going to release parts to use a carbon fibre tube instead of the 3D printed arms if people would rather do that.
