Just so it's clear, I didn't just put that EM chart together.  I've had it for awhile and it took quite a bit to put it together.  Didn't want to give the impression that I just worked on it for 30 min and then voila.

Funked -
Airframe data just from whatever sources I could find.   Base performance data from AH flight tests.  Both sets of data used in multistage calculations.  Methodology reviewed by Wells (bless his soul :) ).  

Not sure if I'm using the same methodology as Badboy but I wanted to give him a chance to finish his charts before comparing notes with him.

Hazed -
believe me it takes quite a bit of work- multiple steps involved in the process, all needing double and triple QA passes to make sure you've got good info.  Then the charts are only good for a given set of flight parameters.  I barely have time to fly in my free time as it is :)!  I'll see what I can do but it may take awhile.  I don't intend to post other charts but would rather wait to see the full set that Badboy publishes when he is done.  However if I put a D9 chart together I will share it.

Wilbus:

There are no piper cherokee's in AH to compare the La-7 to.  And the controls in AH aren't really connected via rods and cables to alierons etc... so you don't "feel" the aircraft the way you do in real life.  Your comparison is meaningless.  Now if you took a stopwatch, trimmed the rudder to neutral on takeoff and measured yaw with neutral controls then you might have some actual data for comparison.  Right now all you are saying is that it doesn't "feel" right to you.  if you want to show some error in the flight model you are going to have to perform measurements and make some calculations (that icky math thing again) and compare that data to real life Lagg data.  Otherwise you are just pouting because the game modelling does not match your baseless opinion.

My Masters degree in Applied Physics says Funked is spot on. :)

funkedup,

I will concede that you are correct however please explain the following problem.

Given an electric motor at 1000 rpm and 3HP what is the Torque of the motor?

Give your answer in SI units.  Show your work and explain the units that you use for angular velocity.

Back to Lame-7.

When in 190, it is the plane I hate most (together with C-Hog and Tempest). It runs down even the Dora, outperforms it in most categories and is is one of vulchee's favourites.

Even when being one of the most common vulchee planes, it maintains K/D above 1. That speaks a lot.

A cheap perk, 5 perkies, I'd say.

I agree Hristo, the 190d9 should be perked.

LOL, it takes so little to start a perk-it discussion ;)

Dunno, I have rarely seen D-9 and P51 suicide takeoffs from vulched fields. Not so with Lame-7s. That speaks something. Don't underestimate the dweeb factor - they are very good in discovering their rides ;).

Wanna perk D-9 ? No problem with me. Whenever I flew the thing I had K/D which would never rob me of it. But generally, it would make a fairly rare arena plane even more rare.

You what? That's utter BS. Last tour the D9 ranked 7th in terms of number of kills attributed to it, ahead of the 109 G10, F6F, P-38, both the 190 A5 and A8, any of the F4Us, or Jugs or Yaks.

It didn't get that number of kills, sat in the hangar. Rare? lol!

BTW, Spit9 and P-51D are both ahead of La-7 in number of kills... what does that tell you?

La-7 is an outstanding fighter...I agree about it.
but I feel AH's one is wrong in something....

In real life, La-7 was bad (unstable) at takeoff/landing.
Doesn't it mean La7 had a bad handling at slow speed?
and it had a tight tapered wing, doesn't it have bad wing-tip stalls?
AH's one is really stable at low speed....easy handling...too easy to recover from spin. I feel it is strange.

In the second place, La-7 can accelerate to the top speed like a rocket. But its engine diameter is big. Doesn't it have a large profile drag? (I mean drag setting might have error in La-7...)

Thirdly, La-7 can fly and fight without 1/2 wing very easily.  Actually I shot down bandits with it. Is this model correct?

OK Mitsu out...Sorry for poor English. :(

P.S
This is whine though...I hate to see some pilots do a high -G loop in La-7. :( It's pretty weird....

funkedup,

Nevermind I figured it out.  :eek:

Well, there is a real world tested flight envelope available for the P-51. AH is a game with a generalized flight model...
