SOH-CM-2025
It's been a while since we've updated the community regarding the project. We are in final testing and post production work to ready the package for release and like we've done in the past the SOH community will be getting it first in a limited discounted release. This is a 2020 package. We are timing the release to follow 2024 so we can evaluate compatibility. More on that when more is known. Here is a short video of some of the functionality. Note the Wwise sound package by SimAcoustics.

Hello,
A few words to describe the add-on, it is a complete development since the Super Stearman differs from the PT-xx in several points .
What are they?
- a different engine Pratt & Whitney Wasp-Junior of 450 horsepower with booster pump,
- fully Wwise sounds that were subcontracted to the company SimAcoustics which made these recordings on a real Stearman (D-EMDV in Germany),
- advanced engine management to have in your hands something other than a basic aircraft, including the management of wear and breakdowns that can occur to the engine,
- a new VC much more complete equipped with a GPS,
- new animations to increase immersion in the use of this plane,
- and a graphical interface for managing the addon completely new to make pre-flight visits.
Wasp-Junior engine,
This engine has been fully modeled, and its specific characteristics taken into account in this add-on. Particular care has been taken to respect the power curves and start modes of this capricious but tried engine.
The flight model was approved by two recognized pilots: BeeGee and Branstormer
I can assure you that the 450 hp are there at the take-off and with the sounds of SimAcoustics ... it’s a thrill!
Advanced engine management
The engine modeling under MSFS is quite basic and although it incorporates fault management, this one is nevertheless very basic.
We decided to go further in this modeling by managing several points left out by Asobo/Microsoft:
- radial motors require very special care due to their design which has been taken into account,
- engine oil is now considered as fuel, that is a mass that can vary during your flight and has its own characteristics (consumable, temperature, efficiency, possible leaks),
- cylinder head temperatures (influence on engine life),
- the phenomena of detonation (influence on the performance and life of the engine).
An unused radial engine has oil from its cooling system accumulating in the lower cylinders during extended shut-downs and special procedures are planned to mitigate this.
These procedures are of two types:
a) pullthrough which consists in manipulating the propeller so that it drives the engine and the oil pump, which has the effect of circulating the oil and emptying any accumulations of this liquid at the level of the cylinders.
If these instructions are not followed, the engine may start but the accumulated oil can cause harmful overpressures in the cylinders and trigger breakdowns.
The number of brewing to be realized is calculated according to certain parameters and via the "tooltips", precise indications are provided to the user.
b) priming, to be able to start as a function of the outside temperature and that of the engine, a certain number of pulses on the PRIMER are required to ensure that the engine has the correct amount of fuel in the fuel system. Again, depending on certain parameters the number of pulses needed is calculated and displayed via tooltips.
The engine oil tank is now considered as a full-fledged tank that can be filled or supplemented/upgraded. The engine oil will be consumed during flight and its mass will vary influencing the behaviour and distribution of the masses.
This substance has a very important characteristic: ts temperature.
Below a certain value which is usually 40°C, the oil cannot work properly to lubricate the engine so if the user does not respect the times of warm-up and uses the engine power too early, it degrades performance (needle of the manifold which is agitated with strong tremors).
This also affects the engine temperature (which increases more rapidly when several effects are combined) and can cause irreversible damage, thus engine failures.
To be able to manage the oil and its temperature, different elements are modelled.
- OIL BYPASS button
This lever allows to short-circuit the oil circuit that goes through the radiator and thus allow a much faster temperature rise of the oil.
The user should monitor this lever as it can lead to overheating and failure if used for a long period in the ON position.
- pump lever overfeeding
In the critical phases of use of this aircraft (take-offs, acrobatics, landings) it is necessary to put on the electric pump to compensate for a failure of the mechanical pump.
This pump increases fuel flow during these critical phases.
This fuel supplement (richer mixture) also allows to "cool" the cylinder heads by way of consequence.
Attention, it also affects fuel consumption!
The engine oil helps to cool the engine and its temperature constantly changes. The user must monitor this temperature and regulate it via the engine controls or the two previous levers.
If the oil temperature is around or above 260°C, it quickly causes "fatal" effects:
- the temperature of the cylinder heads (CHT) will increase, which increases the wear of the engine (parameter also modelled),
- the increase in oil temperature also prematurely increases this wear,
- oil leaks may occur due to excessive oil pressure.
All these events are managed by local variables and different thresholds that can influence two other modelled parameters such as wear and engine condition. This allows to trigger outages.
The detonation phenomenon is also modelled (very modestly) if the motor is used in non-appropriate ranges:
- too much power for too long,
- use of an inadequate air/mixture value,
This phenomenon is modelled through additional variables as in the case of oil.
To increase immersion, it is possible using our new interface accessible via the toolbar,in order to:
- read the different checklists,
- to perform a complete pre-flight visit from the cockpit view (validation of moving surfaces, oil and fuel supplements),
- to have a status tab and the real-time vision (period of 10s) of certain variables to know the degree of wear of the engine and read some essential parameters.
The pre-flight visit always starts from the cockpit in internal view[ and by clicking on a schematic view of the aircraft switches to predefined points in advance allowing you to interact with the flight controls or trigger animations (oil or fuel supplements).
Non-contractual image:
Last point, this advanced engine management is not unlockable: it is basic (no Eazy mode exist) so the use of this aircraft must be done in accordance with the manufacturer’s instructions otherwise you risk to wear your engine, cause engine failure or destruction.
The possibility of being able to find his plane in the state it was left on the next flight is allowed via a new function enabled by the SDK: persistent data. To be eligible, the aircraft must be able to complete its flight correctly, land without any problems and the flight must be stopped in accordance with the rules of the art.
ATTENTION, you must exit the flight by the interface and not by clicking on the X icon in the upper right-hand corner because in this case, the MSFS function cannot be performed correctly.
In case of irreparable failure, the user will have to finish his current flight, return to the interface with the world map to be able to restore some parameters to their default value.
These are the main features of this new Stearman, which allow me to say that it is a new supplement and not a product updated.
PS: Some deliveries that you could see in the captures that were presented could not be included in the add-on because the owners asked for incompatible amounts with the sale price of this add-on (Red Bull, D-EMDV). However, it is planned to distribute these textures as freeware after the release of this add-on.

Sounds like a PITA. No sale here.

Actually it's very easy to bypass the persistent wear values by using the reset switch in the data. The only requirement is that that aircraft be stopped on the ground engine and battery off. Resetting set the plane back to factory "as new" Also all the start up sequencing can be bypassed as well by using the EFB page 2 select "Ready to Fly" and click done. Off you go no troubles.
I'm sorry, IMHO that post is kinda rude. Uncalled for even. There happen to be people who like that sort of thing. Some even expect it.
I happen to think that GAS/Spad54/Lagaffe have brought us lovely stuff so far, for all sort of sims. And always at decent prices.
I'm sorry if I offended you with my reaction, but I happen to know the people in this outfit, and they're the nicest and most knowledgeable people I've ever been in contact with.
Cheers,

I humbly ask that you have this airplane fully 2024 capable when you release it. I really like your products and specially like the Stearmans. However, having moved on to 2024, I will no longer be buying 2020 add-ons. And, I do want this airplane in my virtual hanger.

To answer to your question: "fully 2024", an honest answer is no.
I explain, for me an aircraft "100% compliant with 2024" is an aircraft that can be used:
- in career mode and
- which allows a pre-flight as it is defined in 2024.
Currently, there are still many bugs in the 2024 version that you can use. It is for that reason that yesterday Asobo has released a patch to migrate the 1.0.88.0 version in 1.1.9.0 version.
The SDK is not finished and the most difficult point on which developers try to change Asobo’s cap is the visibility on aircrafts provided by default. For now all files of the default aircrafts are encrypted so not readable.
With an SDK that is not finished, the documentation has a lot of paragraph in state "To be defined", if one can’t read the CFG files and other configuration files to do reverse-engeniering to migrate an existing plane for 2020 into a "full compliant aircraft for 2024" is a utopia.
Not to mention the fact that the export plugin for 3DSMax has some problems, that the one for Blender (used by a lot of developers) has serious shortcomings and that in addition the textures have changed format, exit the DDS we are now with KTX2 which according to Asobo can only be created by their built-in compilation tool. RhumbaFlappy has given on FSdeveloper.com a way to use an opensource software to manage this format.
Under these conditions, it will take at least 6 months for the SDK environment to improve and the 3rd Party Dev. community can be able to achieve a full compliant aircraft. It's my opinion.
After I do not say that some studios like PMD, Aerosoft or others who maintain privileged relations with Asobo/ Microsoft can not do better.
Besides this aspect, it is possible to realize an aircraft that is fully operable under MSFS 2024 but using the state of the art of MSFS 2020.
In our case, we took 3 months to develop a proprietary interface to make a pre-flight that is acceptable from the point of view of features and graphics.
The passage of our latest creation under MSFS 2024 that will allow to use all the functions we have created and without bug detrimental to uilisation of the add-on is being done.
Since last Tuesday, I look every day the official forum of developers and I have already opened several tickets on bugs that we discovered. Some things are starting to move in the right direction but it is necessary to give a little time to Asobo to react, decide on a direction of improvement and make the various changes needed.
For thus who want have more informations on the current bugs and question asked to the Asobo support, follow this link for the Q&A forum.
Some developers have announced that they will make patches available very quickly for their product without giving any more explanation. Honestly I think these patches will be neither more nor less than what we are doing: patches to make their add-ons functional but without using all the functions of 2024 described above. It's may developer opinion.
Excuse me if my English is not academic: I’m French ... but I like working with my new friends from GAS

Then the for me is, Yes. I do not care for the Career path, nor will I do an walk arounds, other than to try it once or twice.To answer to your question: "fully 2024", an honest answer is no.

I am interested if the airplane will look and fly correctly.
As far as "privileged relations", earlier tried the Carenado PC-24 (which is why I paid $140 for the Deluxe version) and half of the controls either didn't work or the animation didn't work but the control did. Go figure? I guess I will have to fool around with until I get everything working.

If you’re going to quote another post, please use the quote function. Your post confused me because I hadn’t read Lagaffe’s original post for a number of days and I thought you were posting the information about the persistence yourself. So the whole thing made little sense to someone only reading newer messages in their current session.
Please people, let's stick to the plane's development here. If you're not interested in the plane for whatever reason and need to express that, then doing so in a respectful tone is allowable. Calling someone out when they do is not, regardless of your opinion or the tone of their post. There is a "Report" link under each post if you feel a post has crossed any sort of line - please use that if you feel the need.
As for me, the mandatory wear goes against my normal flying habits, since I like to just be able to jump in and fly. I'm also more a fan of small to medium multi-engine GA.
Please consider this my "wet asbestos blanket" post. I don't want to pull the handle on the hangar-filling foam generators....

Good morning,
To be clear with all those who read my posts: none of GAS Stearman is currently 100% compatible with FS24 according to the criteria I stated above.
I’ve been working for more than 3 weeks to see exactly what needs to be done and I’m testing various solutions: that’s the only thing I can say.
Thanks to read me.
