I have 5 flights on mine now, seems to be pretty straightforward to fly. I keep it on full elevator throw with no expo, it seems soft on the elev.

180 RX works well especially witht he grass runway for now. I tried to balance at 220mm, I am pretty close, it just is a little nose heavy with TO since the tank is a little fwd. So far no issues. Looks great in the air although it seems a little small!
