There seems to be an uptick in Political comments in recent months. Those of us who are long time members of the site know that Political and Religious content has been banned for years. Nothing has changed. Please leave all political and religious comments out of the forums.
If you recently joined the forums you were not presented with this restriction in the terms of service. This was due to a conversion error when we went from vBulletin to Xenforo. We have updated our terms of service to reflect these corrections.
Please note any post refering to a politician will be considered political even if it is intended to be humor. Our experience is these topics have a way of dividing the forums and causing deep resentment among members. It is a poison to the community. We appreciate compliance with the rules.

Hi TiAr, first of all, you did an magnificent job sofar, I would gladly pay money for such an outstanding looking aircraft!
I am not a native german or english speaking person but understand both languages well enough (have to if you're Dutch...) If I could help you in any way just let me know.
kind regards,
Marijn

Just used the google translation about the Zweitluftsystem (Alternate Air System) in Mark 1:
Zweitluftsystem: Das System verhindert das Eindringen von Feuchtigkeit in die Sammlungskammer des Triebwerks. Das muss unbedingt verhindert werden, da sonst das Triebwerk nicht mehr ordnungsgemäß funktionieren kann. Das System besteht aus zwei Staudruckeinlassklappen, einer Ventilationsklappe und einer Zweitluftklappe an der Sammlungskammer.
Bei normalem Betrieb sind die beweglichen Staudruckeinlassklappen aus der direkten Staudruckluftzuführung heruntergeklappt. Bei Kaltwetter-Operation (5°C oder darunter), unter sichtbar feuchten Bedingungen oder bei Schneefall, müssen diese Klappen geschlossen werden, um die Staudruckluftzuführung zu blockieren. Der nun entstehende Unterdruck öffnet die Zweitluftklappen hinter der Sammlungskammer. Die Luft strömt nun aus dem Triebwerkraum in die Sammlungskammer. Zusätzlich öffnet sich eine Außenklappe an der Unterseite der Motorhaube, um den Triebwerkraum mit kalter Luft zu versorgen. Diese und die Ventilationsklappe sind im Außenmodell animiert.
Dieses Zweitluftsystem wird über einen Hebel auf der rechten Seite der Konsole bedient (ähnlich wie der Hebel der Kühlklappen bei der Piston). Oberste Stellung ist das System offen (NORM), in der untersten Stellung komplett geschlossen. Wenn man noch im Cockpit den Engine Anti Ice-Schalter aktiviert, ist das Zweitluftsystem aktiv. Wie in der Realität hat der Betrieb des geschlossenen Zweitluftsystems einen deutlichen Leistungsverlust zur Folge.
Secondary air system: The system prevents the ingress of moisture into the collection chamber of the engine. This must be prevented at all, otherwise the engine may not function properly. The system consists of two dynamic pressure inlet valves, a ventilation flap and a second air damper on the collection chamber.
In normal operation the movable back pressure inlet flaps are folded down from the direct impact pressure air supply. In cold weather operation (5 ° C or below), under visible humid conditions and snowfall, these valves must be closed to block the ram air supply. The now resulting negative pressure opens the secondary air flaps behind the collection chamber. The air now flows from the engine compartment into the collection chamber. In addition, an outside flap opens at the bottom of the bonnet to feed the engine room with cold air. This and the ventilation flap are animated outdoor model.
This secondary air system is operated via a lever on the right side of the console (similar to the lever of the cowl flaps in the Piston). Supreme position, the system is open (NORM), in the lowest position completely closed. If the engine anti-ice switch is activated even in the cockpit, the secondary air system is active. As in reality the operation of the closed secondary air system has a significant performance loss.

Sounds good. Three points:
The collection chamber. To what part of the turbine engine is that referring? I think combustion section?
1. The inlet section
2. The compressor section
3. The combustion section (the combustor)
4. The turbine (and exhaust) section.
"Supreme position" : upper position.
"flaps": doors

I know, the collection chamber? Sammlungskammer is inside the engine cowling. Behind the inlets - at least the Mark 1 has three intakes - one is on the top of cowling (I am quite sure this the important one) and 2 are left and right. German Manual says nothing more about them.
Wiki says about the Allison 250 C20:
Allison adopted a reverse airflow engine configuration for the Model 250: although air enters the intake/compression system in the conventional fashion, the compressed air leaving the centrifugal compressor diffuser is ducted rearwards around the turbine system, before being turned through 180 degrees at entry to the combustor.
Perhaps, collection chamber is wrong translated, better is centrifugal compressor diffuser...
English handbook would be nice - but I have only a German one...
The "Zweitluftsystem" is important for me, because inlet-flaps are animated in models and system closed impacts performance like real.

I was only being sarcastic about google translate, but actually it didn't do too bad for a total translation. That's the thing with google translate; you really need to keep translating sections, or sentences back and forth between languages to find the correct translation, and sometimes you need to concentrate on one word at a time. Sorry my German is not good. I can sometimes figure out individual words, but for text translation I would be useless.

Yes I noticed it some time ago. But there is no 3D-adaption possible at the moment. But I am quite sure, you can use it without working 3D knobs in P3D instead of RXP (which is not available for P3D).
News - German Manual is 100 % finished, send it today to the betas. If you have a bit time the next days and you are willing to help me out for English translation, PM is more than welcome.
And there is a new picture out of P3D VC Floats with some new details to see.

Looks very beautiful. The Flight1 page says you run their tool and choose the "replace Reality-XP" and it works.
