Not a frequent Yak flyer, and most often when I do it's been the 9u. But I will offer get in close, Yak 3 especially accelerates quickly, and at low alts climbs like a rocket, but ballistics of the gun are not great, So I like to get in under 300 yds. And mostly only shoot in short bursts, if you shoot well nose mounted guns are a big plus IMHO. Also, I like to keep it fast, as I think turn rate degrades at slower speeds.
