AKK FX2-Ultimate and AKK Nano 3 5.8 GHz VTX reviews and tests

Continuing good relations with AKK Technology, I have received 2 new 5.8GHz VTXes for review.

First is FX2-Ultimate, with power output up to 1200mW.
Yes that is a lot and in the mean time, during some FCC rules , they announced that maximum power will be limited to 1000mW on next production line in the future.
That is quite OK and enough
