Was originally worried about buying a 550 Hex clone frame but I am very impressed with the quality of this frame. All holes lined up as expected and the integrated power board soldered up great. I have built several name brand frames and would put this right there with them.
With this frame I strictly use it video photography and soon FPV. It does not get tossed around or abused so keep that in mind.
Plenty of room for my Naza M Lite flight control board along with the receiver, as well as my brushless gimbal on the front.
If you are looking for a sturdy, well built hex for video then I would suggest this frame.
