well ive been using the g6 but allways seem to lose out in a turning battle see my thread what am i doing wrong the k4 is even more of a flying brick when it comes to turning etc you have to really keep an eye on your speed
all i can say is stay FAST and get really close before you let rip with the guns becuse at close range they will eat any other plane in seconds

i think they are best suited to boom n zoom tactics so if you good at boom and zoom (i aint lol) then these are ideal planes to use
ive just started using la7 yak 3 and they seem to be a lot more niffty
