I agree with Nuchpatrich, the scissor maneuver is really your only hope if the pilot is worth a darn. Remember to use your flaps and if you happen to get a shot at him at any time, you better get hits in.
Realistically, the only true way to defend against the La7 in that situation is to not get into that situation because 85% of the time your gonna have to hit the silk.
To that end, I still don't believe the La7s flight model is based on actual Russian data from a reliable source. I don't remember one time when the Russians have ever released accurate data about any military equipment - ever. Granted they release data, especially after the cold war ended but by no means is it accurate. There is no way they produced such a stellar aircraft that has virtually no weaknesses.
Power to weight ratio: excellent
acceleration: excellent
top speed: excellent
compression at high speeds: minimal
visibility: good
durability: good
firepower: good
low speed handling: good
climb rate: excellent
At this point in reading, most people will start getting out their books and quoting numbers to dispute the above generalized assessment. Think about it though, planes are made with a purpose in mind. EX - the F6F was designed from the ground up to destroy Zeros. It does that well and proved itself to that ability in the Marianas Turkey Shoot. It can turn well, it's rugged and is excellent at carrier ops but has weaknesses in top speed and compression as well as climb rate & acceleration.
The Fw-190 was designed as a high speed gun platform to destroy allied bombers, the plane was designed accordingly and as a result it has difficulty in turn fights due to wing design etc. It has weakness due to design!
Another example, the Zero was designed to outturn anything in the sky, not designed for speed, and as a result it can't dive and compresses badly at high speeds. It has weakness due to design!
The La7 can outturn any energy fighter, can out accelerate any plane (not perc'd) except one, it hardly compresses in a dive, it climbs like a rocket, it's fast as snot, the pilot can see well out of it, it holds it's energy with the best of them.... I can go on... My point - what weakness does it have?
The sad thing is, even if HiTech drove to my house and showed me the data they used, what could we do about it? Nothing. We may never know how the real La7 flew. I just try to stay out of the way of them and relish the times when I see them going down in flames. That's what the MA is all about, the ability to fly any plane at any time.
Kuben <-- braces self for HTC'ites that think HiTech is infallible
