Been flying La5 bit this month, I've always preferred it over the La7, as for all it's short comings only one I consider is fuel range, you have to climb and cruise and low rpm to gain any range and chance of RTB. Turns ok, awesome vertical and acceleration, WEP seems to last as long as there is fuel in the tank (not long under WEP)
As for guns they can take down most fighters in one pass under 250, lot more powerful and more ammo then the Yak

Probably point I dislike the most is views compared to the Yak, but at least the La's have been updated to AH2 which makes up for it.
