I use a gaui 330SX.
It took less than 1 hour to build trim and fly. very easy.
It is incredibly stable and easy to fly. So I knew straight away I could FPV this without even a spotter.
I took it to the field the next day and did my first 9 minute FPV flight.
Took off and landed FPV too. No problem.
Before I wanted to use a Trex500, but was too nervous. Using The Quad 330SX I am relaxed (though I will FPV the 500 one day).
Using Sony SN555 camera
really awful nano 5.8 gig video tx/rx (dont buy one!)
Spektrum ar7000 receiver
I have on order better video gear.
Also just fitted Black Stork II OSD. That was easy to fit.,
