The la7 is a better plane, though it doesn't perform as well as the Yak3 in the MA as a whole. They both get around the same # of kills but the Yak3 normally has a .2-.3 better K/D. The Yak3 is much smaller and much harder to shoot down from a dead 6. It takes much more damage. Planes that can escape the fight or cons on their 6 the fastest always have the best advantage. While 1v1 I might give it to the La7, most of the time it will come down to the pilot.
The C205. Now there is a plane for a real challenge. Like anybody wants that.... Lol
