The vRAAF is running a server to host important flight model changes to our aircraft. At the moment, you will find changes to the F4F-4, P-38j, N1K2j, Spitfire & the Zero has recieved a much awaited upgrade. There are also changes to damage models.
This server is open to the public & we have 2 close fields for that great furbally experience 
By all means, test, test & test if you can. Please report any problems such as logging on. |

OK hero! Heres a link to log files. Two are examples of trying to load the testing module you've graciously hosted. In previous discussions, we've chatted about the inability to load certain files. Hope this is a small help...

OK, looks like you had a couple time synch errors to start. Nothing I can do about that unfortunately. The "couldn't load "/tr/planes/n1k2/n1k2_ext.anm" I will look into. |

Edit; open the n1k2j.acm file with a text editor, replace these lines;
[Graphics]
external = n1k2/n1k2_ext.anm
internal = n1k2/n1k2_int.anm
with these lines:
[Graphics]
external = n1k/n1k2_ext.anm
internal = n1k/n1k2_int.anm
My bad. We split the N1K2 & N1K1 files on the Dev copies but I forgot we even did that.
Anyone else having problems ? |

060608 06:49:28 Unable to open file "_airfoils/a6m2_tip.acm"
060608 06:49:28 SCENARIO: couldn't load model "/tr/planes/a6m2.acm".
---------------------------------------------------------------------------------
Bads, I sent you another A6M2 folder last night that has the new historic wing in it. Can you instal this plane inc foils, this should resolves the issue above.
-------------------------------------------------------------------
Sorry guys, we working day jobs as well and struggling to get enough time to keep up at the moment. There is a number of updated FMs comming through from me and i'm sure your keen to try them. This beta arena is designed to test these AC and once we get on top of the bugs, it will be a valuable asset for guaging your opinions on newer models. I have been working my way through the series increasing detail and building wings/airframes based on new techniques and data as it comes in (historic foils data for Zero found last week).
This is a two fold process:
1. To increase the detail and accuracy of existing models, and
2. To prep the planes for 0.65 and the extra capabilities it will offer.
This process will continue and we should have a set of planes ready for 0.65 with any luck. In the mean time 0.64 will have a revised set of planes to trial as they become available.
Updated
P38 (series)
F4F (series)
A6M (a6m2 only ATM until I finish the others)
N1K (series)
Perhaps the B25 next?  |

Any early indications of what to expect from the new Zero? Draggier? Faster? Squirlier? Smoother? What? |

Zero has slightly reduced performance & F4F slightly increased.
I have updated the server with some corrections. Let me know if you still can't get on. |

The Shinden George’s sight doesn't seem to be lined up correctly. I'm not sure if it was like this before though...
I wonder how the zero can be any worse in this sim. Its already slow, rolls badly bleeds speed like hell. Not sure what else could be done to keep any noob in his P38 safe  . |

Fuji, are we flying the same Zero????
Yes, it's slow, but compared to all the planes it really WAS slower than. It's on par with an F4F, and that's as it should be. It does roll poorly, but it should; that's its Achilles Heel at speed.
Still, even with these shortcomings, it's absolute DEATH to F4Fs flying alone, and to anyone stupid enough to dogfight it. Things change in later war, and that's absolutely correct.
Actually, I think our Zeros to date might have been a little ueber in the dive. While you can't match a P40 or F4F in a rolling dive, you can still stay with him pretty much until he flattens out on the deck and then doesn't have any options left. From what I understand, the dive and roll should be an absolute escape maneuver against a Zero, especially one who doesn't manage elevator trim well.
So, I'll be interested to see what baders means by, "slightly reduced performance". |

Word of advice here, we don't want insiteful comments, we need objective critisims based on data.
----------------------------------------------------------
F4Fs
The new F4F engine is based on data from the P&W engine docs I have, but the manual is OTW from USA to clarify some points. The F4F was just a plain lousy sustained turner, it has had about as much as can be done to make sure it is close to correct physical properties turn wise. Wing loading of the A6M2 is far superior to the F4F and thus it will allways out turn an F4F. You need to be aware of the fuel loads in the F4F, it really is a slug when full of fuel.
Some facts and points of interest:
1. The F4F took 5.22 secs to do a 360deg roll at 250mph (max roll 69deg/sec), hardly insparational. (AHT p475)
2. Terminal dive velocity was Mach 0.66, it will dive no faster because of drag. (AHT p488).
3. It was rated a poor diver by US pilots (AHT p489).
4. F4F-4 generally rated as completely out classed by the Japanese Zero (AHT p94).
Sustained turn on the F4F-3 is abt 18deg/sec (7150lb) and slightly less in overload fuel condition. The zero A6M2 with it's light wing loading is abt 24deg/sec 'sustained' turn.
-----------------------------------------------------------------
A6Ms
Development of the Zero is one step above the correct size and shape, the rest is to be determined as the series progresses but i'm confident it's more accurite in a lot of areas than the previous version. I spent a lot of time verifying the wings shape (thanks to Kodama who sent the historic data this week), I spent 10 hours on the foils alone making sure they are as histoirically accurite in shape as I can manage. I'm happy with the build to date and the result was a small loss of about 2 deg/sec on the lighter A6M2. I'll continue with the series over the next week and see how they shape up as well.
------------------------------------------------------------------
P38s
These have had a total rebuild as well, can we investigate the DM on these planes as they 'should in theory' be the first planes to have a damagable radiator to engine link. This has never been trialed before and if it works out OK, I can include this on all inline engined AC (a soft spot).
Don't smile too much you radial pilots, your engine has oil coolers and these are my next trial.
--------------------------------------------------------------------------------
N1Ks
I am aware of the gunsite in the N1k2, this is due to the differing art we are using ATM. We thought that the flight data of the N1K2s was a point that needed our investigation. I deceided to rebuild the planes based on what I knew and had on my HD and any data that could be supplied by our Japanese friends. The resultant N1K2 seems to be a lot closer to the expected performance figures I have seen at least. I laymans terms, it's had a lot of dimention corrections and control changes, most of which seem to have lowered performance as an end result.
----------------------------------------------------------------------------
The object of this rebuild was more accuracy, not to hinder one and boost the other because 'I want to' per say. You need to appreciate that the end results of my builds are the results that eventuate by building ACMs to identical guides and perameters, and always based on my data. There are a number of global changes I have incorporated in every model to correct issues with teh 0.64 engine, which when 0.65 is release I have marked to be set back to defaults.
I will not bend the flight engine physical parameters to majically give more turn (although I could). What I can do though is adjust the feel and perhaps the CoG control limits of the AC to be inline with correct end result data.
The feel of the planes should be better at least and IMHO closer to the turns they should have as well. I continue to develope these planes as new data indicates, so dont worry it's never finished.
It worries me that a late war fighter like the J2M can take off at 55mph and that the B25 struggles so much with its load? Both of these may have issues and once rebuilt, will probably be much more expected in the end as a result. So expect me to be busy working on FMs for a long while yet and as a result you guys get to try new planes for free |

Great Work!!!! Is there a place we can get our hands on performance data to flight test against? Unless you've flown one of these birds in RL, "feel" is meaningless, as you know, and I'd like to check out the flight envelope completely versus actual flight test data, if possible. |

a lighter a/c should have a better power/weight ratio = faster turn. |

Peril all TT's Liquid cooled planes alreeady have this feature by a long time and it work quite fine so i think that you can do it witout any problem. [/quote] |

Does anyone know what was the practical difference difference in radial engine's oil cooler leak and inline one's?
I have read Focke Wulf pilots could often return from british coast after hits in oilcooler had caused oil to spill out, while 109 pilots were less lucky. I have one such account in a book somewhere. Pilot was from channel front unit that switched to 190s and then back to 109s and thought this as one of main advantages of radial engine. I'll check it out later. |

It's not so much the difference between their oil coolers as it is that a radial is primarily AIR cooled while the inline engine is primarily LIQUID cooled.
So, while both could benefit from glycol (basically, antifreeze!) and a radiator... the inline engine was much more dependant on having that system function very efficiently.
Oil starvation is an altogether different problem, although it manifests itself with heat (plus wear) would probably be very detrimental to either engine very quickly. |

Fabry, sorry I should explain more.
TR has also had radiators for a long time in the P40s/P39s/Spits, I worked on these a few years ago; however, the previous damage model for radiators didn't really function as a component of the engine from what I understand. I dont think anyone has tried setting the radiator as the 'parent' of the engine, distroy radiator should now mean engine dead I 'think'.
That's why we need to test it, it's slightly different to TR & TTs existing radiator design. |

Yes Peril i've understand and yes we are currently using engine parented with radiators in TT.
From c202 ACM as example

fire = /tt/particles/_leak/fire.par

where a plane have radiators positioned far from the engine like under the wings or under the fuselage this kind of structure is a must , but when radiator as for P40 is really near to engine it's redundant .
That's why i say go on with it ! |
