Yeeaaa That's just so great,

Thanks a lot, (even It will brings down some mythology that was starting to appears on that forum about some planes)

But Morghot is right, can you udapte that file to say what sensitivity you used for each plane, or was it the same for each one. ???
Because it changes a lot your results. For example if you use 3 notches down for each one, you lost a lot for the LA5-fn or for BF109s.

EDIT: sorry for the Edit but I just found the info about sensitivity on your file. You say 10 of 20 clicks. With that configuration for all planes,

Even if I agree with yourcomments, the sensitivity that you chose is biasing your datas.
- it brings an over estimation of performance for Spitifires, P51, FWs
over LA5fn and BF109s

Indeed with 8 notches down (with means 10of18 notches) you only lost 3 notches from a full turn without rudder on the Spit while you lost 8 notches for the LA5fn and 7 notches for BF109-F4

Thanks for taking the time to do this.

How do you know you were at a exactly 50 degree climb?

you can see this in the virtual cockpit. Pretty good skill if you could keep it at 50 degree the whole time though. In real life this is easy with trimming, but in the game it is impossible to keep the plane exactly were you want

Very interesting widar thanks a lot for publishing the results. It's always interesting flying with you and panzergranate-you guys are incredibly knowledgable.

Nice. Although your results of turn and roll are flawed because of the constant sensitivity setting, The Top speed, Dive and Climb rate stats are all very interesting. Your conclusions are still valid and well made. Damn some of those top speeds are way off. You are right about the gondola cannons on the 109's, They were also said to ruin the planes maneuverability but in BoP the gondola 109's handle just as well as the clean 109's.

Thanks for your response.

The gondola's on the Me 109 G-6 do degrade performance in BOP, check the Me 109 G-6 test results regarding BOP maximum sustained level speed, roll and turn rate in seconds etc. as compared to the BOP Me 109 G-2 and Me 109 G-10 test results. These three aircraft in real life were not all that dissimilar to warrant the discrepancies in BOP test results.

Actually I find that to compare the aircraft honestly all must be tested at the same sensitivity setting, the conditions must be the same for the tests results to be comparable. In the end it does not make that much of a difference in many ways. I'll explain this in more detail.

For instance, I spent a lot of time testing the P51 and Fw 190 models, both in single player and online, since they are some of the worst performers in BOP. My Xbox live friends and I found that when we did this test:

Two Fw 190's flying online in formation both making 360 degree rolls at the same altitude and speed, one with sensitivity setting 20 of 20 and one at 10 of 20. The difference in roll rate was not even one second or a second at most. We could not believe this at first and tested it about five times in succession with the Fw 190 A/F-8 and with the P51. The same happened in 360 degree turns. The major difference appears to be that it is easier to enter into a spin or stall at higher sensitivity settings and not that it makes an aircraft way more maneuverable in return.

We also did some testing of this kind with the I-153 with more or less the same results. The same for dive and climb testing with Spitfires and Me 109's.

So the higher sensitivity settings are actually more hurtful than harmful online for the average virtual pilot based on testing.

So based on testing, I would have to disagree with you on your sensitivity remark.

No, he is right. You need to calculated max turn/roll rates with sensitivity at max.

For planes like La-5/7 or Yak, you will get wrong numbers because max deflection is not reached when sensitivity is reduced - a compromise they had to make on the sens slider.

Turn sens to max on La-7/5 or Yak and you should get much better turn times.

This is a huge advantage to the good turning planes when you don't mess with sensitivity.

Thanks, I hope that the forum members and developers make use of the testing results.

It is always a learning experience to be on your wing, to this date you are the only virtual pilot that I have seen that owns on an Me 109 G6, even once while being outnumbered three to one by the three Polish Spitfire pilots. Considering how bad the Me 109 G6 BOP test results are, that is quite a feat.

Thanks for the feedback.

You are right about the view, all testing was done with the virtual cockpit since this gives the degree data I needed.

Of course some aircraft are more stable than others in BOP, so with some it was easier to keep the climb or dive at a 50 degree angle. I probably should have written that down also, but flying and timing was work enough as it is.

All in all it was a lot of work and not the most exiting at that, but the results in my opinion are exiting, or at least useful. I hope that players take advantage of the data, because it gives hints about what tactic works against what aircraft. I also hope that the developers fix the historically incorrect unbalances that the testing has revealed.

I also did a lot of gunnery testing but have not gotten around to putting that test data in an table format yet, since all this takes a lot of time. Some results of the gunnery testing, to an extent, have been incorporated in the remarks in the test data list.
