After couple rebuilds with my KISSv2 electronic around my frames I decided to settle it on ImpulseRC Reverb. Pretty pleased with this decision. All fits nicely.
It is bit too heavy with Hero7 and CNHL 1000mAh 6S so I am thinking of buying Session5 or Runcam5.
I've put some Reveb PIDs I took from user shared pids and it is running very smooth with clean HD video so I am satisfied on that part.
