so the competition has released yet another machine and in the meantime Yuneec sit on their hands and H520 sit on shelves gathering dust, what is going on in Yuneec ?
If you're talking about the P4P v2, I'm not sure that's exactly an awe inspiring leap. The H520 has had the quieter blade technology since release, and with six motors runs its engines under a lot less stress - so it's quieter and reliable. It's nice that DJI are catching up though

Yuneec are being pretty quiet, but we're coming up to the second anniversary of the Typhoon H launch, so the H Pro is likely to land fairly soon. That's probably why DJI are making so much noise about a minor upgrade.
We'll see what happens with the H520, but I suspect we'll be seeing an update or two before long. After the last year, they seem to be being ultra-cautious about firmware releases.
