The hardest part of turnfighting the La7, and the thing that 99% do wrong in every plane but is particularly bad in the LA7, is they never chop the throttle. Lots of folks think the La7 (and several other planes) dont turn well because they never back out of WEP. They throw it too the stop and run wide open, but the key to the La7 (and again several others but the La7 in particular) is throttle control because of its incredible acceleration. Learn to use the throttle, which in the La7 can mean long periods at 0% throttle, and it can turn with almost anything.
