Diatone ZMR 200 is ready to fly.

The power distribution board is a complete fail, don’t buy it. It burns out or if you are lucky you get horrible video noise and the OSD vanishes when applying throttle. There is a fix for this: soldering external capacitors. However I don’t feel like fixing complete boards like this with huge capacitors which make the build look like crap. This quadcopter needs a rebuild with new PDB and maybe even a cheap FC with OSD.
