I picked up an Argonaut Hexacopter V2 frame from Multirotor Superstore. The frame offers some nice features and is reasonably priced for a carbon fiber composite design. Overall, it’s design is too asymmetric for my taste and requires fairly high PI settings in order to hold pitch attitude while flying in manual mode. I also disliked how the FPV camera position left the camera lens vulnerable during a front impact. I would recommend other hexacopter frames over this one, like the Grasshopper or Venom.
I designed an ABS bracket that mounts the FPV camera further back, preventing it from crashing into the ground. If you’d like a bracket, please message me!
