Hi, I am looking for someone who is selling a pixhawk flightcontroller. I need it for a quadcopter I was making but the current flightcontroller which I have which is a APM 2.8 is proving to be very outdated and underpowered and moreover due to a crash it got physically damaged to a point that it won't work so hence looking for a new and better flightcontroller which can support latest firmware and software
