I just finish my plane.
I took some extra time to build a carbon fixed gear for this plane and I tried to do it looking like a 2x2 F3A.
I'm satisfied of the result :
In flight, the plane is very neutral, knife edge is very easy to do like with an indoor plane. I fly with around 30 kph of wind, probably the hight limit for this plane of 785 g.
I use 4S 2250 hyperion. It's good for windy condition and permit to have a real good speed for schedules.
