Kind of sounds like the design analysis and combat flight reports I was reading today. It had a superior low alt sudden climb against the Bf109-G6 and earlier models. And it regained speed quickly at lower combat alts. Supposedly the small narrow tapered wings gave it low speed stall problems that happened suddenly starting at the wing tips and landing\take off stability issues. I don't see many Yak3 in the game wing stall and auger low and slow. They just seem to float out of it while spits around them auger. But, the manuals for Yak3 and spit from WW2 never tell you to pop flaps to low speed turn fight. Online games are hotbeds of pushing the limits of simulated things that were never pushed that way in real life due to the problems with dieing. In our game we try to fly everything like it is an RV8 on steroids with guns. I'm not sure many would know how to evaluate Hitech's rides like a real WW2 pilot would for the same conditions and outcomes that existed in his real life.
I was reading A6m analysis reports today of combat tests against allied fighters. Could not find any references to popping flaps, dragging for an overshoot, spiral climbing to pitch back against the lower plane's stall. All references to HOing did not sound good for the A6m and was considered a reasonable tactic against A6m. Then in our game, I see A6m win HO all the time and fly on.
Now I did watch a film of a Yak3 in NZ this year on landing clip a loading crane with it's wing. The wing snapped off at the mounting point for the landing gear motor mount. The rest of the air frame handled the subsequent grinding around on the ground and the pilot got out OK. Since the Yak3 became the magic ride dejur, I've listened to many complaints about the wings being indestructible while the air frame absorbed all kinds of hits with no damage. Or, fly the Yak3 and it will screw your Internet connection until you land. Who knows................
