Aerodynamic moment: Rudder deflection creates an aerodynamic moment in the yaw direction, which also has a small arm with respect to the roll axis, causing a rolling moment.
Differential lift and drag: Pressing the rudder pedal produces yaw, but also some roll. The wing opposite the depressed rudder side travels through the air slightly faster, creating more lift and contributing to roll.
Minimizing the effect: Coordinated rudder and aileron use can minimize the roll effect.
Different planes roll more or less than others with rudder input due to a variety of factors, including dihedral/anhedral, wing sweep, and in sims, flight model detail/accuracy.
thanks so much for the explanation. let me be a little clearer on whatās happening.
when i depress the rudder pedal without any other control input, the plane will snap roll like i have fully deflected the ailerons. just like that. there is almost no movement around the yaw axis as youād expect. itās not āsome rollā, itās all roll.
this doesnāt happen on any other plane so i am not sure whatās going on.
if the plane started to yaw and ultimately ended up in a roll, i wouldnāt mind but thatās not whatās happening. i own every single other plane from this dev and while there are a couple i donāt fly so much because i donāt care for them, for the most part i have really enjoyed what heās done. this plane defies physics and i am disappointed
Having seen a video of this effect in action on the Wittman, I back up what @scoobyx is saying. Itās grossly beyond anything based in reality. Itās not a snap roll. Nor is it normal yaw-roll coupling. Itās like holding the ailerons hard over in the Extra.
A lack of understanding of how real planes fly doesnāt make this a bad sim aircraft.
A lack of direct real world experience does not make this a good sim aircraft.
Finally had some time to pick this up and I am very impressed with it. Really liking it so far!
Questions:
What is this red bottom light meaning? It is always on.
I seem to have problem with the battery after about 40 mins of flying. After that time, as soon as I put the engine to Idle, all lights, gauges on the co-pilotās side and the voltage die off after about 2 seconds.
Before 40 mins, I can idle and itās OK (for a decent amount of time at least). Surely if the alternator is charging the battery during a flight leg at high revs, it would not die almost instantly when I idle? The alternator switch is on, as is battery etc. Cannot see what I am doing wrong there.
Also I think I found a bug with centre tank. I ran out of fuel near end of my first flight and I was on centre tank. I changed tanks and the engine came back to life but the centre tank needle was always sat on zero, even when I was running from that tank. Maybe these 3 things are connected?
Is there no manual anywhere for this one?
Also I noticed my friend in multiplayer has pink missing texture for the whole windscreen in the same plane.
And his aircraft label (ICAO) starts with ānanā (not a number?)
Oh and in the W10, when I started āready to flyā it said my EGT was too high on the main glass display, but I donāt think it was?
Finally got around to flying the Tailwind again. The only way I got it to do a āsevereā roll from rudder input was to quickly kick full rudder while flying. And thatās something you just donāt do in a real plane.
Might be a case of rudder curve sensitivity on your setup. (Looking forward to FS2024 where this can be tuned per-plane!) On my setup, reasonably small rudder inputs did add some roll, but that feels authentic from reading pireps on the real Tailwinds, and you can compensate by coordinating your turn with a combination of stick-and-rudder. (Something thatās SO much easier in a real plane where āfeelā helps as much as the instrument, versus sim flying where you only have the instrument as a cue.)
The manual is here:
(Community-folder)\lhc-aircraft-wittman-tailwind-series\SimObjects\Airplanes\LHC_Wittman_Tailwind_W8\Manual\Tailwind_Owners_Manual.pdf
I think it will answer many of the questions above. The āEGT tempā on startup is documented, just toggle the display and itāll clear.
ProTip: Install Agent Ransack, the super-awesome-and-fast freeware search tool that should be built into Windows in the first place, and search your Flight Sim folder for *.pdf periodically. Youāll find some handy treasures! I copy the PDFs over to a OneDrive Manuals folder that I keep syncād to my iPad for easy reference.
Itās a shame thereās not a standard file structure for documentation. (That could be accessed from the Hangar in the sim to pull up a PDF if itās thereā¦ Hey Asobo/MS, free idea for you for FS2024)
Ah! I hadnāt noticed the lightsā¦ (āWarning light? Engineās on, Iāll ignore it.ā āWhat are 'Things flight sim pilots say that real pilots who value their lives never would, Alex?ā)
Oh @LyonHaart001 can you chime in on those, good sir?
i donāt need to kick the rudder to induce a roll. i can press slowly and once the rudder is deflected the plane rolls like i am holding the ailerons at full deflection. maybe this is the way the real plane is (iāve never flown one irl) but it doesnāt feel realistic. thereās very little yaw and mostly roll. my expectation is that with rudder deflection youāll experience a bunch of yaw and if you donāt correct it will develop into a larger roll but not as rapid as this plane rolls. anyhow, just want to make folks aware of the very strange behavior i am experiencing
From your description, Iāve sometimes have this happen on a variety of planes. Just touching the rudder pedals with roll the plane like I was slamming the pedal down.
I think there is something wrong with the sensitivity settings in the sim. If I go into the sensitivity settings for my rudder pedals, and toggle them from one profile and back it, the problem seems to go away.
i appreciate it but i am not having this issue with any other plane. for comparison i ran a test against a couple of other planes just to make sure my control settings werenāt causing issues. on the other planes when i press down on the rudder, i get a yawing motion and if i continue to apply rudder the yawing motion gets greater and i also start to notice roll being induced.
with the tailwind, i get very little yawing motion when depressing the rudder but as i continue to depress the rudder, i lose all yawing motion and it becomes all roll.
i am happy to take this one on the chin if i am doing something wrong or my controls are messing me up but i havenāt been able to replicate this behavior on any other plane.
My apologies for missing these posts. I need to check in here more often.
3 lights on the W-8 instrument panel /////
Top to bottom; Flaps, Parking Brake, and Carb Heater. Mid way through the build, I went with the fully electronic modern (todays version) fuel injected model which would not have a manual carb heater on it. I test flew it myself, as I never remembered that light being on, and it wasnt when I tested it. I wonder if you have a panel setup at home, and if you have your carb heat switch on?
Excessive Rudder /////
I never hit her with full rudder. I never noticed that she did a full rotation, and she does. I will adjust this. For me, in the tons of hours I tested her, I never noticed or came across this. I did many redoās of the flight models to get her to where she is, but had never fully hit her with max rudder. She is touchy, but never maxxed it out.
When making this plane, keeping in mind that Steve Wittman was a racing plane designer, I wanted her to have āsnapā in the ailerons, close to what a Pitts or 330 would have, but not as extreme. Snappy but not like a 330. But not via the rudder. Something went wrongā¦
Engine EGT Max //////
This couldnt be tuned out of the package. For some reason, this shows up on the bootup of the plane. If you click through the dial on that EFICS instrument, it clears it, and youāll see its running proper. This is told in the Checklist and in the Manual to flip through the dial 4 clicks to clear it.
ICAO = nan //////
oopsā¦
Pink Windshield /////
Interesting. This means missing texture or low memory. The windshield with its overlay scratches layer, I think, takes a lot of RAM or VRAM. Iāll investigate this, but usually, if your resources are maxed out, this can happen. When you reboot the plane, or reboot the sim, the issue is gone.
I worked really hard on these little ones. I wanted them as perfect as humanly possible. I am in love with these planes and wanted their models to represent them as best as I could.
Iāll retune that rudder and check the electrical system. I never once had electrical issues. Butā¦ I may have missed something.
I remember a steering issue several months back with the Viking. We tested it for months. The team found no issues with steering. I didnt have any issues with steering. On release day, I found out through a very dark review, that the Viking had reversed steering brake inputs. None (none) of us had rudder pedals. We didnt know the brake pedals had accidentally been reversed. grizlyā¦ I had held back release multiple times to fix little bugs, but some still got through. The ultimate test is public release.

That is an awesome ideaā¦ We need to be able to access the PDF manuals on these planes in the sim, somehowā¦ The guys on XBox have no way to access these that come with the download, so they have to search for the download link. I have started putting the PDF download links in the MS Store data on the plane. That way they can at least download it to a iPad or tablet and have it there.
Photos of my panel, no carb heat light on, engine off and engine on.
I have Logitech switch panel but that has only Cowl Flap, De-Ice and Pitot Heat switch. Will try again later with those and see if it goes off. It could be De-Ice doing it guess.
What about the Battery and Fuel tank I wrote?
This
I seem to have problem with the battery after about 40 mins of flying. After that time, as soon as I put the engine to Idle, all lights, gauges on the co-pilotās side and the voltage die off after about 2 seconds.

Anyone pick up the STOL version? I wish Iād known this was coming (though I realize Lionheart didnāt plan it at the start!) as this is more the kind of flying I do ā bush stuff.
But Iām wondering how different the flying experience is from the main package? Itās certainly inexpensive enough that I should just check it out, I suppose.
Editer,
It is radically different, to say the least. I found this plane by mistake, a real aircraft. I loved it so much, I made it. Its an existing W10 but with a wingspan 6 feet wider, high performance IO540 engine, massive 2 bladed manually adjusted pitch style prop, and mods to tail, wingtips, wing spads, vanes and extensions on the flaps, etc. Whats cool is flying it around in a hover sort of way, keeping it above stall. Fully laden, it stalls at I think 45 knots, so at half tanks she floats quite well. She can jump off the ground, but not like those with small engines and liter weight airframes. StorchStein is a little heavier. Heavy duty airframe, thicker tubing.
The International LOC file finally arrived, so hopefully she will be out in the MS Store in 2 weeks. She has been out at SimMarket now for 2 weeks already. Quiet release, no complaints.
I priced it very low, half of the price of the original Tailwind package, figuring, if together they are 18 USD, then one would be around 9 USD. I didnt want to add it to the original set as people were upset that the package was so massive. 10GB footprint for those two.
16 paint schemes. I went nuts again on repaints. These are diff paint schemes from the W10ās and W8ās. Wings are larger and different. Some look nicely kept, and some are weathered and rough. Craig said he had to make the landing gear high for I think 6 inch ground clearance off the ground with tail up. This guy is a big time bush pilot, loves the W10ās and wanted to make one that could do what he wanted.
Thanks, Bill! After you went to all that trouble to reply, I had to drop the eight bucks to pick up the plane!
Really nice! Definitely handles differently than the W-8/W-10 with that bigger wing. I appreciate the STOL tips in the manual! Had a fun time getting in and out of a couple of really right WA rural airports on my first test flight.
Certainly not going to nitpick at the bargain price! But a couple of suggestions if you revisit the plane for an update or for FS2024:
Surprised with the awesome number of repaints that you didnāt include the actual"Storchstein" paintjob! Would love to see N13XZ included.
Craig mentions increasing the tail size:
The Lionheartstein looks great, but the tail looks tiny compared to that huge wing. Itād be cool to see the tail surfaces tweaked to be a bit larger proportional to the wing, as the in hte real plane.
Not dissatisfied in any way! Just a couple of suggestions to make a really cool variation even better.
I had held back release multiple times to fix little bugs, but some still got through. The ultimate test is public release.
