Kilo, I'm no stranger to the 152... Before moot made his little public interest enhancement plan, I was flying this thing for a long time. I may not be as "good" as some others in it, but I am VERY familiar with how it handles.
In general while I might not be the best "fighter" I am by many other people's suggestion a good "pilot" (virtual one, that is, and talking about this game specifically).
It's very unstable longitudinally. We had even the slightest hint of instability in the Brew and it got fixed instantly. However whenever discussion of the 152 instability comes up the same old answer is thrown out as if to stop all further discussion. It's got long thin wings.
Well so do a number of other planes. Perhaps not this bad, but those other planes have rock-steady gun platforms. If any of them acted like this folks would cry bloody murder.
Only other comparable situation is the spit14 instability. This is worse than the spit14, but for all intents and purposes is just a modified 190D. The 190D doesn't share ANY of these problems. Not even in the slightest. It has a similar engine with regards to horsepower. It has a nearly identical fuselage (slightly shorter nose, less v-stab area). It simply has shorter wingtips.
Logically speaking if the 152 is a direct modification from the 190D would not the 190 series show SOME signs of these problems, even if just minor signs? The 190 series is rock steady. The 152 is terrible. It does not follow (as the saying goes).
