RE: Turnigy H.A.L. (Heavy Aerial Lift)
I did some testing with my H.A.L. and it seems that the GoPro gimbal is really optimized for a GoPro and amplifies the wobble when using my FlyCamOne due to the fulcrum offset.
By placing the H.A.L. on my G.P. CG Machine, I could easily move the pitch of the quad and observe both the camera and video stability. Since the fulcrum is not optimal for the FlyCamOne camera, it amplifies the servo step size. I think it's time for a GoPro!
