I searched for kopis 2 but many seller are out of stock.
I only found there https://www.getfpv.com/holybro-kopis-2-6s-fpv-racing-drone-pnf.html .
But at the https://docs.px4.io/master/en/flight_controller/kakutef7.html the picture at the top says that kakute f7 is v1.2 .
What a chance 
kopis 2 has v1.5.
What about kakute f7 hdv which is installed on Kopis CineWhoop. Is PX4
compatible with that board?
Note: Paypal is forbiddened in my country and swift is too expensive so i don’t check Holybro’s own site.
