Thanks,
MSFS Team

Surprised nobody has mentioned this yet, but I’ve found the cowl flaps to be bugged and not productive in cooling the engine. Anyone else have that problem? I’ve also found it’s very difficult to manage engine RPM, but that seems believable to me from what I know about the aircraft, having not had the privilege to fly one myself.

Absolute joy as a glider, and lovely artwork.

For me the Speed Brake didn’t work :frowning:
Tried I manual from cockpit and nothing.
On external inspection the speed brake didn’t show and can’t be proofed. Seems they forgot them?

did the Speed Brakes work for you? If not, how do you land?

The speed brakes work fine for me; I just have them bound to a slider, but I think they’re somewhere to the left of you in the cockpit, IIRC.I didn’t discover any issues other than the cowl flaps not cooling.

Maybe double-check whether they’re considered spoilers or speed brakes? Might need a slightly different bind. I forget if 2024 handles the two separately

Unfortunately, this Stemme S12 is not yet a device that could be called ā€œstudy levelā€.

Let’s hope that future updates will raise the level of this wonderful bird.

I tried them with the lever with blue header on the left side of the cockpit left of the flaps. The tip says speed brake the lever moved but nothing appear and no speed reduction. didn’t have a spare axis on my normal joke, will try to exchange throttle with speed brake and mapping key assignment to it. But in cockpit few should work in first place.
Thanks for the answer :slight_smile:

Great bird!

2 things urgently need to be fixed:

Autopilot only holds the direction in a very poor way. Feels like it“s drunk being in HDG/NAV mode.
Spoilers / ā€œairbrakesā€ have no real effect. When these things are out, the bird should descend really fast. The angle of attack would also have to be changed here, otherwise it sags. (So that it would be realistic)

Same way you land any open class glider ā€œkeep going downwind until you’re scared, then go some moreā€.

It’s an open class glider, if you don’t nail the approach the airbrake handle is more something to hold onto as you go through the hedge at the far end of the runway.

My big question is ā€œwhere is the cruise/climb switch?ā€. That and the almost total lack of adverse yaw is why the gliders in MSFS are such a joke to the gliding community.

Even if I deactivated the copilot I sometimes have one in the Stemme. As she is looking beyond spooky Iā€˜d rather like to fly alone.

Anyone else having this ?

Is the co-pilot weight set to 0 in the EFB?

Yes, have checked this.
In the manual it says there is a clickspot, but only for 2020.

The Cruise Climb switch is betwenn the seats
"TakeOf/Cruise)
It is a toggle switch located behind the throttle
Still i find the speedbrakes to weak.
As example
Arcus with fully extended spoilers, gets a sink rate of more than 6-7 m/s

I find the rudder in msfs2024 much closer to reality than in msfs2020. Now you can really push hard without virtually falling out of the thermal (nearly). In 2020, the thermal has disappeared after a courageous kick in the rudder - just as you would do in real life to circle thermals

I created a bug report topic for the spoiler bug, feel free to upvote

Another bug report, for the vario https://forums.flightsimulator.com/t/stemme-s12-vario-not-working-properly/684371

The cruise climb switch between the seats changes the prop pitch. Cruise/climb in a glider is a vital switch affecting the vario mode switching it from ā€œclimb toneā€ to ā€œspeed to fly toneā€ used for cross country soaring.

Unflyable. All controls (Throttle, Elevator, Ailerons, Rudder) are not working.

Can’t get rid of copilot (same as optica). TAS on pfd instead of IAS. TAS on lx9000 no option for IAS and groundspeed not shown.

Another bug report, for motor losing power
