I can't hit anything unless I'm within 200 with taters.
Yea, deflection shots are a different story though, get enough lead and 600yrd shots aren't hard to make.
When I fly the K4 I try to keep my plane above 250mph at all times, gives me enough speed to climb up or dive quickly if I need to get away from trouble.
Don't make the mistake of trying to turn often, for people new to the K4 it's more important to E fight a bit more than you would and learn the torque/stall characteristics at slow speeds. When you get more familiar w/ the K4, going from a turn fight to an E fight in the blink of an eye won't be hard. Practice Practice Practice and experiment w/ different things, best way to learn a new plane.
