Since I'm partial to the La-7 in MA, but play a lot in Mid-War, I read this thread and thought I'd give the LA-5 a whirl. The thing is, I know the LA-7 has a reputation as something of an uber plane, but I don't use it as a BNZ'r, and it was also my favorite plane in my old sim, Fighter Ace, when NO one else flew it.
So, last night I upped an La-5 in Mid-War for several hours. One thing I like about the La-7 is that it is a decent handler at both high and low speeds with the right combination of throttle, flaps, and rudder. The La-5 seems to compress and lose torsional rigidity at high speeds. For instance, I had someone on my six, low alt at >300 mph and pulled a full throttle split-S and barely avoided the ground, whereas the La-7 would have had room to spare.
Anyway, just thought I'd throw that observation out there from an La-La'r.
