Hello,

thank you for sharing your opinion about this sim!

To your 172 stall speed notice:
The AeroflyFS Cessna 172 was initially set up fully loaded (4 persons and full fuel tanks). After one of the patches the weight got reduced to fit the normal climb performance better. Maybe it stil is heavier than your real C172 which makes it stall quicker.

Another possible explaination is the calibration of the airspeed in your real C172. The simulated pitot tube does not simulate the airflow effects of the nearby wing. As the angle of attack increases the pitot tube messures less accurate. This effect is even bigger mear a wing because the wing affects the airflow in front of it aswell and redirects the air in an even higher angle in relation to the pitot tube. That results in a falty messurment of the airpressure which the airspeed indicator relies on.

In short: The real pitot tube suffers effects that are not simulated.

It is possible to fake such an effect in the AeroflyFS. You could reduce the messured airspeed as a function of the angle of attack and the yaw angle. It means extra work and a proper calibration messurement in the real aircraft which is also expensive. And on top of that: Not every C172 may have the same airspeed indicator. Some airspeed indicators may be show another calibrated airpseed (CAS) than others.
The saver way is to let the simulation aircraft stall earlier but with the same angle of attack.

I can't say this enough: Its not the speed that creates the stall its the angle of attack!
Technically you could fly mostly by an AOA indicator. It would be much safer than a airspeed indicator. (Speedstalls, CAS, TAS, etc...)

Many good flights,
Jan

Hi Andi,

es kann sein, dass ein 3D Modell in der tmd zweimal verwendet wird. Z.B. könnte dies in der GeometrieList der Fall sein oder auch als CollisionHull. Jedenfalls darf jedes Objekt des 3D-Modells nur ein einziges mal als CollisionHull sowie in einer einzigen GeometrieList vorhanden sein...

Gruß,
Jan

[...] Aber wo finde ich in meiner Fernsteuerung den Simulatormodus? [...]

Da jede Fernsteuerungstyp da verschieden ist, kann ich dir das so nicht sagen. Am besten die Anleitung der Fernsteuerung durchstöbern oder eine kurze Internetrecherche starten!

Edit: Wie Jürgen richtig erkannt hat ist der Simulatormodus hier nicht hilfreich, da das Signal von der Fernsteuerung ganz normal gesendet wird wie beim Flugmodell.

Hallo,

das Problem scheint offenbar nicht im Rc7 zu liegen, da bereits unter Windows das Steuergerät nicht richtig erkannt wird.

Schau (ggf. nochmal gründlich) in die Anleitung des RX2SIM und deiner Fernsteuerung (Simulatormodus?) und wende dich, falls weiterhin erfolglos, an den Hersteller.

Wenn die Steuerwerte am PC wild durch die Gegend springen, kann es auch sein, dass ein Wackelkontakt vorliegt.

Jan

Hallo,
Du musst dein Steuergerät richtig kalibrieren. Zuerst kalibrierst du das Steuergerät unter Windows bzw. Mac und anschließend nocheinmal im Simulator. Die Kalibrierung speichert für jeden Input die Wertw für die Vollausschläge und Neutralstellung.

Hi,
you know that the aerofly Rc7 offers an option to scale your aircrafts, right?
Cheers,
Jan

Quote from Lukas2.2

Gibt es schon eine Lösung ??
Es fühlt sich so an als würde das Modell Höhe und Seite gleichzeitig machen, wenn man höhe zieht.

Lösung gefunden!

Der Aerofly RC7 simuliert jetzt wohl anscheinend die Kreiselkräfte des Propellers! Wenn du die Massenträgheit (Intertia) des Propellers herabsetzt fällt der Effekt weit aus weniger ins Gewicht.
Mensch, da hätte ich echt auch früher drauf kommen können

Da muss ich Jürgen zustimmen. Ein Simulatormodell in einer guten Qualität selbst zu erstellen bedeutet hunderte Arbeitsstunden. Bei einem normalen Stundensatz könnt ihr euch selbst ausrechnen, wie viel Geld ihr zahlen müsstet.

Meiner Meinung nach ist es nicht zwingend erforderlich genau dasselbe Modell im Simulator zu fliegen wie in Realität. Wenn ihr mit mehreren Simulatormodellen eine saubere Platzrunde fliegen könnt bei verschiedenen Windverhältnissen wird euch dies mit großer Wahrscheinlichkeit auch in echt gelingen.

Ich bin früher den Easystar einmal selbst geflogen um ihn für jemanden einzutrimmen. Er ist wirklich gutmütig und robust! Wenn ihr also im Simulator Modelle beherrscht, die viel schneller unterwegs sind und viel schwieriger zu landen sind, ist der Easystar wirklich einfach zu fliegen.

Jan

Hi everyone who is involved in this thread!
I have been teaching myself to use a glider after Jan's helpful instructions and am working up to completing 4535jacks' challenge. I have a question about gliders that I would like to put to anyone who is willing to help. When I fly the discus, there is a beeping sound that changes in pitch, and gets faster or slower. What is it? I was wondering if it has anything to do with thermals maybe?:confused:

Hi,

thats the electronic variometer sound. It creates a sound for the pilot so that he can continue to look outside.
The sound layout is modulated in the following manner: If the aircraft is descending the sound is continuous and has a lower frequency if you are losing altitude more quickly. If you are inside an uplifting windfield (thermal/slope wind) and the vertical speed of the aircraft is positive (climbing) you can hear a pulsed sound that gets higher pitched if the strength of the updraft increases.

So if you hear the sound beeping thats a good sign for a thermal, if it sounds very deep then you should fly a bit faster and try to stay outside that area.

Regards,
Jan

Hi,

I don't know if its available in the ipad verion, its called "show windfield in simulation" or something similar. In the PC version it is below the sliders for the wind velocity, direction etc.

Have a great week,
Jan

This is something you cannot answer in one posting. Its best to read a lot about that topic and do some internet research. You'll find some videos of flight instructers etc. on YouTube and other video platforms.

For now take this advice: Make the thermals visible with the checkbox in the wind settings. Its best to approach a thermal of to one side and then fly constant circles around its center inside the tube that simbolizes the thermal in the aerofly FS. That way you gain the most of the updraft and the airplane gets pushed up.
When inside a thermal circling you need to fly slow, just above the stall speed. If you are to fast you'll fly around it, if you are to slow, the aircraft will stall and lose altitude.

How not to crash:
Let the airplane fly and look way ahead how the course of the airplane should be changed in the future. Use only limited control inputs to reach your target, fly with as little stick movement as nessessary. If you overreact with a huge surface deflection you risk losing the control over the airplane.
If you want to do a safe landing you need a proper and long final aproach. Stabilize the aproach as soon as possible. The closer you get to the runway the smaller the adjustments are that you can make.

Good luck and have fun,
Jan

Hello there,

I did the exact same challenge the other way around and I can agree it really is a beautiful route. I also flew once from Sion to Samedan, landed and flew back later via Saanen to Ecuvillens. I selected a moderate wind from the south and flew almost without thermalling along the ridges. I estimated the overall speed to be 160 km/h which is quite impressive for the Discus I think.

Another "challenge" I like to fly is flying from Sion to Birrfeld with the Discus, again with some wind from the south. If you are high anougth at Ullrichen you can fly pretty much straight all the way to the finish, crossing over Alpnach and gaining the last bit of altitude before a very long final glide downhill. Its pretty strategic if you try to reach Birrfeld asap. If you fly to fast you land short, if you fly to slow you end up much to high. I ended this challenge with a low pass at Birrfeld, a standard cirquit and a nice crosswind landing with rollout to the tower. That was great fun and also very challenging.

Another route took me from Ulrichen to Locarno in the south. Flying it as fast as possible makes it very interesting because you have a long way with wind from the front

Gook luck have fun,
Jan

Hello Sylvian,

yes that would also be possible, but you could also use the existing hover-trainer for training for now...
Select the hovertrainer from the menu strip and move the sliders in this manner:
Engine: 100% Manual
Pitch: 100% Manual
Roll: 70% Trainer
Nick: 70% Trainer
Gear: 100% Manual
Height as desired.
Hit "Start" and you'll have a self-stabilizing heli.

If thats not what you wanted, please load one of the quadrocopters (e.g. the MT2208) and set them up so that the flightmode is on normal not acro mode. They have a strong self-stabilizing gyro in them which can be used in helis, too, I think (havn't tried it out). Is that somewhere close to what you want your heli to fly?

Cheers,
Jan

Hallo Jürgen,

du hast zwei Möglichkeiten den Rollwiderstand eines Rades anzupassen:

1) Interner Modelleditor des RC7

Mit dem Modell im Rc7 geladen klicke auf das Menü "Modell" in der Menüleiste und wähle den Eintrag "Modell bearbeiten".
Auf der linken Seite unterhalb des Baumansicht findest du eine Dropdown-Box "Anzeigetiefe", dort auf "Experte" umschalten.
Nun in der Baumansicht im Unterpunkt "Fahrwerk links" das linke Rad ("LinksRad") anwählen und auf der rechten Seite den "Rollwiderstand" erhöhen (z.B. 0.1). Das gleiche für das rechte und das Bugfahrwerk wiederholen, dann das Modell testen und anschließend ggf. weiter anpassen.

Wenn du zufrieden bist, solltest du das Modell abspeichern.
Dabei kannst du einen Konfigurationsnamen eintippen und eine Beschreibung verfassen. Der Konfigurationsname ist der Name, der in der Dropdownliste angezeigt wird unterhalb des Vorschaubildes und der Dropdownbox für die Bemalung. Die Beschreibung wird dann darunter in dem größeren Textfeld angezeigt.

2) TMD editieren

Falls du eine eigene Modifikation erstellen möchtest und das Original behalten willst, solltest du als Erstes von den Datein "as-twinstar2-gear.tmd" und "as-twinstar2-gear.tmc" eine Kopie anlegen und diese dann umbennenen in "as-twinstar2-gear__000.tmd" (zwei Unterstriche!) und "as-twinstar2-gear__000.tmd".

Nur wenn du eine neue Modifikation erstellen willst, öffne zuerst die as-twinstar2-gear__000.tmc und verändere den "DisplayName" um in der Auswahlliste einen Unterschied feststellen zu können.

Öffne nun die as-twinstar2-gear.tmd bzw. as-twinstar2-gear__000.tmd (je nachdem ob du das Original überschreiben willst) mit einem Texteditor (Wordpad, Notepad++) in dem Ordner, in dem du den TwinStar installiert hast.
Springe direkt zur Zeile 820 oder suche nach "LeftWheelHull" und verändere dort den RollingFrictionCoefficient von 0.03 auf z.B. 0.1.
Wiederhole das Vorgehen ein paar Zeilen tiefer für "RightWheelHull" und "FrontWheelHull".
Anschließend die Datei abspeichern und das Modell im Rc7 neu laden.

Viel Erfolg!
Jan

Hello Sylvian,

its not possible to edit that in with the aircraft editor. But almost everythin is possible using an external editor for the tmd textfile.
What exactly is your intention? Does the heli have a restricted roll and pitch angle of 45° to either side? That would be possible to program!

Regards,
Jan

It's at "Meiringen", the small building in a northerly direction of the building with the tower. Didn't go though on PC...

Hello there,

if you visit their facebook page you can already see a screenshot of a helicopter!

Direct link: https://www.facebook.com/photo.php?fbid=608450885914493

So there is already at least one heli in development and it looks great

Bests,
Jan

As the developers of IPACS said several times before, they are going to publish when the program when it's complete and as bug free as it can be.

[personal opinion, don't quote them for the following text!]
They are not going to risk an unfinished version that is unstable or anything like that and they might come up with a great idea last minute and work on that for a while. But nobody hears about that, because then they don't have to argue with people that cannot wait. Sometimes they exclude some features aswell and then everyone would say: But you promised...
They are working on it, don't you worry.

--> It's coming when it's finished and it's going to be great!

Cheers,
Jan

Visit their public Facebook-Page and take a look at their screenshots: https://www.facebook.com/Aerofly.Flightsimulator

Its the exact same prosess as for aerofly 5 aircrafts. Search for and download the "aerofly5 developer tools". They include a manual how to create a new aircraft from scratch.
You can also visit my homepage aerofly-sim.de within the Google translater and read a bit about that topic there, too.

Bests, Jan
