as far as maneuverability math guys go the usual suspects here like to isolate a single issue and claim that it determines the maneuverability of an aircraft
These are not claims. These are facts. You can look up the formulas for turn rate and turn radius yourself, if you care to. The fact that you do not understand the physics involved does not invalidate it, anymore than heavy objects fall faster just because most people believe they do.
when we all know it is a combination of several factors that can only really be sorted out in real world testing ...
Actual side by side testing is mostly unavailable for most aircraft in-game, and when available, frequently contradictory.
Further more, if you actually believe there are "way more factors" in maneuverability than are known to physics, then you can't apply ANY test across the board in a blanket way. Since you apparently believe that happy thoughts or whatever $#Q%@^%@$% it is this week can contravene the physics of lift, thrust, and drag, there is no way one could expect the results for a G-14 with an Mg 151 onboard to be applicable to the same G-14 with a Mk. 108 onboard. No sir, you can't just figure for the extra weight and go from there...'cause you don't believe in physics. You have to get out your tape measure and check the turn radius of a real G-14 with one, then re-arm and try it again...'cause you got to account for all the mysterious and magical factors, don't ya know. And of course, this will only be Thorsim's turn radius for the G-14 in game, surely another pilot's size and weight would throw all kinds of un-calculable factors into it.
Hmmm...physical laws are mutable nothing can be known except by word of the "learned authorities"? Just who is an "authority" is a matter of debate of course...of course, if you're Thorsim its whoever supports your original idea most neatly...My God, we have a valuable example of the Medieval mindset in our midst that I have never appreciated up until now.
