Hi, yeah i am wondering if the flight models for the La's will be updated or reworked aswell, looking at the inhancements, its not just eye candy in alot of cases.
If anything, im wondering if it will bleed more speed when doin' 180's to get behind someone, dive/climb better..or worse...so on and so forth.
Noticed most planes that got redone to ahII standards useualy fly a bit* different aswell.
Any word HTC?

I believe FM changes was done for all aircraft a long time ago regardless of new or old 3d model. The Mosquito recently got an FM fix without redoing the 3d model.
-
I think they're just getting a face-lift, as I have not heard anything about a FM change for them.

Pretty sure it was the first la thread aafter the pictures were released someone said no just graphics

I think the comment was to point out that changing the architecture did not change the FM.
We could speculate..........
IMO the La5FN should have a shorter WEP duration than the La7. Probably in the order of 5 minutes at best (pilots notes) compared to the La7's 10 minutes.
WEP performance figures (top speeds etc) were all achieved with the Engine cooling vanes feathered. This could not be sustained and as such it would be limited to the WEP period (5 mins on a La5FN and 10 mins on a La7).
Top speeds on the La5FN was reduced by upto 50km/hr if the engine cooling vanes were not feathered. The La7's general aerodymics around the engine cowl were improved over the La5FN but a similar drag differential would have been in play here.
So we see that both Lavochkins had a massive reliance on the Combat trim (+/- 50 km/hr) as well as Combat engine settings (1600hp/1850hp).
Combat engine settings could never be employed during the 2nd stage of boost (above 4000m) but presumably combat trim could be.
I do not know how HTC might model this within the standard FM structure.
The WEP button could assume to both set Combat trim and Combat engine settings.
Ie the WEP button induces lower drag and more thrust.
Above 4000m the engine speed would not change (when WEP is engaged)but the trim might interms of an alternative drag model. ( So above 4000m the wep button only reduces drag thrust is unchanged as are revs) Given this the engine would still "heat up" when the cooling trim is feathered.
AH's usual linking of WEP period to engine temperature is a handy mechanism because Non combat trim settings will be required to cool the engine.
Further fidelity could be achieved by linking the engine heat rate to air flow such that in climb WEP was reduced to 2 minutes (on the La5FN) and approx 5 mins (on the La7) before engine tempreature became a problem.
Above I refered to "lower drag" infact I would consider that this "lower" drag" be the default we have now. ie in non WEP setting the drag is higher than that exhibited now.
The net effect would be that the exceptional Lavochkin performance achieved in AH would then be much more dependant upon WEP being engaged. An condition that would have to be nutured carefully to prevent it's further use quickly extinguishing.
I note that the La5FN pilots notes indicates under "Weaponry" that ..............
"Precise fire can be achieved over ranges of 50 to 500 meters."
Under stall recovery.......
"push the joy stick away and do not apply any rudder. The aircraft will exit the stall immediately"
Landing............
The La5FN and to a lesser extent the La7 had a very noticable bounce on landing............ pilot attempts to correct this nearly always ended in disaster basically the ac should brought down to a 3 point landing and if it bounces ................just let it.
Pilot attempts to brake before all 3 wheels were down would cause the nose to dive with a high risk of prop loss or indeed a nose over.
Would be neat if this lot could be modelled.
-
A peculiarity of AH is that all planes are visually modelled with closed radiators/cooling vanes. This makes some planes like the 109's look a bit weird I think.
-
it could be that HTC have made a "policy decision" to ignore the effects of FM changes re cooling vane settings.
I dont know what the effect of this would be on the FM's of other ac or whether the benefits and consequences of trimimg such vanes were the same for all ac interms of the ac's subsequent abilities with or without such settings when in combat.
-
Personally when landing the la's, I have the spacebar down before I touch.
That little bit of extra drag seems to help damp out the bounce a bit.
Also flaring then hold the plane 10 feet up, wait till its ready to quit flying, don't force it down seems to help some.
-
I always three-point and stall my rides onto the runway. No bounce, no fuss.
