First time changing my lovely mark4 frame to another one, and I would like to say - its hard to assemble it.
My guess is that this frame is not best option for DJI ( its not enough space at back ) only VTX can be assembled.
The space for stack, its kind of enough, but can be more...

its a CLONE frame, previously I was fly about 2Y on 6inch Mark4, and it was good experience... not getting back to 5inch, well... next days I have plans to test it. and will try to update my experience.

IMHO: for sure will not buy this frame original !!!
