@draygokorvan & @tachtra same here i did a basic troubleshooting and i think a decrease of the value could be enough. If you can make a version of the mod for RSS could be amazing!

Thanks for the great job!

@DraygoKorvan
Thanks for your response and for your awesome mods (including this one).

Digi’s Realistic Thruster mod does not include a visualization mechanic to balance center of thrust with center of mass. I posted a comment about this in that mods comments section and did not receive a response.

Hence why I decided to ask here.
DraygoKorvan  [author] Oct 25 @ 5:01pm 
you should balance your center of thrust with your center of mass with digi's realistic thrusters mod
racso Oct 24 @ 7:28pm 
Is the Center of Drag in this mod equivalent to center of thrust? For example, are the Center of Drag markers in this mod helpful to balance center of thrust with center of mass in space and in planets when using Digi's Realistic Thrusters mod? Or is Center of Drag only useful for aerodynamics in planets?

@Tachtra, thanks for checking. I'm not using that mod, but I reckon some other mod I'm using might be in conflict then.
Tachtra Oct 17 @ 1:47am 
after some testing it seems to be an incompatibility with Real Solar Systems that causes this problem
Tachtra Oct 16 @ 12:37pm 
@Perriax I have the same problem, although it seems to be a mod compatibility issue, since running the mod just by itself does not cause this error for me
Perriax Oct 14 @ 4:10am 
Anyone else notice rain effects on earthlike planet going sideways whenever the mod is enabled?
DigiKitty Oct 10 @ 7:49pm 
@ArchyZavr doesn't seem to work, in the mod settings there is no 'gui options' anywhere.
ArchyZavr Oct 4 @ 12:25pm 
@GadenKerensky you can easy reposition that :
ingame click enter for open to chat -> click F2 -> left-top appear text "mod settings", click it ->
next click "aerodynamic physics" -> next "gui optioins" -> "wind indicator" -> "wind inidcator position" ->
a pink area will appear - move it as where wish.

I hope no ban for link (: : see that https://ibb.co/album/3vPqWH

p.s. thx for great mod
GadenKerensky Sep 29 @ 4:31am 
Is there a way to reposition the wind-speed indicator? As well as making sure it's not obscured by the character model?
DraygoKorvan  [author] Sep 27 @ 4:50pm 
Hi, this mod already supports mod blocks, they just have to provide the appropriate definitions that this mod uses.

You can also do this yourself, if you were so inclined.

Question, if i have my wings on hinged subgrids because i wanted to add complexity to my design, will the mod still take those subgrids into account?
Leo2log Sep 21 @ 1:25pm 
hey, just reporting an issue ive found with this mod where it causes weather on planets to rotated about 90deg to gravity (mostly modded planets). im pretty sure it might be because of some variable that has the same name as something in the weather code or something like that but it causes all the weather particles to just freak out whenever it rains. is there a way for you guys to fix this?
ryangoslinglover306 Sep 18 @ 12:00am 
how does this mod work along with constys aircraft pack? anyone tried it?
Mortibus Ostium (Sparky) Sep 14 @ 11:38am 
NVM, something happened on world load that caused my settings to get borked.
UnCheat Sep 8 @ 2:05pm 
Looks fine on a new world
Mortibus Ostium (Sparky) Sep 8 @ 11:21am 
With the recent update, it appears even minor thrust causes the fire effect to appear
@PrimetimeCasual
as far as i can tell this mod doesnt alter the thrust behaviour in relation to the vanilla behaviour.
if you want a mod where thrusterplacement matter realistic thrusters ( https://steamcommunity.com/sharedfiles/filedetails/?id=575893643 ) might be something that interests you.
PrimetimeCasual Sep 3 @ 3:44am 
Does thruster placement matter? Or is it just drag / lift vs centre of mass?
DraygoKorvan  [author] Aug 25 @ 6:52pm 
you want your center of drag/lift behind your center of mass directly in line with the direction of travel.
@Souls
center of mass above cente rof lift means it rotates as it wants the mass to be lower than the list and thus you want to have theyre center of mass below the center of lift.

the control surfaces should work if mounted on a rotor or hinge but if they are too small they might have no noticeable impact.

someone might be able to help you with direct advice on the construction if you join the discord linked inside the moddescription and share some screenshots or so of the situation at hand.
Raven Aug 25 @ 1:49am 
@Abisius I managed to get the CoL right under CoM, about a quarter of a block lower, and it still just pulls up and loops into it's own doom as soon as airborne. Also, my control surfaces don't seem to have ANY impact on the flight, which may be the primary issue, maybe if I could correct my trajectory I could get control over the thing.

I just tried with some Gyros and it's completely manageable when I have any control over rotation at all.. I was hoping to use the control surfaces only, so that sucks..
@Souls
the shape of your grid has an influence on it, so maybee just reshaping some stuff helps.

i have atm a grid that has a tendency to nose up over distance due to the ramp i have at the back to get on board with a rover, though its manageable and just about 1-2° nose up at around half a km distance.
Raven Aug 25 @ 1:14am 
@Abisius Thanks. I'm trying to make a biplane, but it keeps pulling up wildly at the nose, I'm guessing because the center of lift is in front of the center of mass. It's weirdly hard to fix, I've moved all cargo and all batteries from around the middle of the plane to up the front but the CoM is still a bit behind CoL. Seeing what I can do to trim the tail down, hopefully lose some more weight from the rear.
Abisius Xarvenius Carbensius Aug 25 @ 12:51am 
@Souls
i usually aim to have the center of mass just slightly below the center of lift, toughly around half a block of the given gridsize, as i find it flys a bit more stable that way even with a single wind design.
besides that try to gradually increase the thickness of wings and structure instead of going up in a big wall to reduce drag if you have probs with drag and/or heat buildup as less drag also means less heat buildup.
Raven Aug 25 @ 12:31am 
Any rules of thumb regarding aerodynamic design? I'm assuming the center of mass and center of drag should basically line up on top of each other ideally?
Abisius Xarvenius Carbensius Aug 11 @ 11:23am 
@Rage Embodied
from what informations where given i would go more with bad aerodynamic design as no mentioning of another mod influencing how stuff flies where given, though i also have so far not used a mod that gives you wings to build with.
Rage Embodied Aug 11 @ 11:01am 
@MrMayhem [continuation]
IF IT DOES NOT: the Wing Block mod has a VERY rare issue where wheels do not play well with your airframe, this can cause extremely strange behavior despite most or all other airframes being unaffected, to resolve it: you have to remove the mod from your world and then re-add it after making a save of that world without the mod.

IF THAT DOES NOT WORK: your save is corrupted. Time to make a new world, and frankly, uninstall and reinstall everything, Steam will re-install all your mods so just wipe the board and assure the highest chance of success.

If that doesn't work, I'd say its time to just pick one or the other, and this one does have more applicability despite no custom blocks. But if you're on a fighter-jet kick, I'd do Wing Blocks.

Wing Blocks for MiGs, Sukhois, Mirages, F-15's, etc., this mod for Antanov, Tumansky, Airbus, space-stuff, interplanetary cargo ships and everything that doesn't come to mind from the former list.
Rage Embodied Aug 11 @ 11:00am 
@MrMayhem 2 possibilities, both related to two mods: you are using the Aerodynamic Wing Blocks mod alongside this mod, such as myself, and are encountering an uncommon glitch which occurs due to the overlapping combination of physics, the author of the other mod suggests disabling the physics aspect of that mod and using the blocks as cosmetics.

HOWEVER, you can troubleshoot this as I have used both mods in conjunction without issue for years: disable one of the two mods and test your game. If it persists, switch which mod is disabled and enabled and then try again.

In my experience: if it continues to persist, disable both, load the world, save, exit, enable either of the mods, preferably not both at once to start with, and see if the issue remains.

Much of the time, this permanently resolves the issue.
Rage Embodied Jul 28 @ 3:28pm 
Still one of my favorite mods. Absolutely lovely, works perfectly in all my hours. Made an Antonov AN-225 to scale and it works, can even transport tanks! Also made an Mi-24 to scale and it works, and a MiG-25, Su-27, B-52, Il-76, Su-39 and they all work just marvelously :)) Thank you for the mod and the hours and hours of fun!
congratulation @MrMayhem you found out how you can build a ship that uses aerodynamics to lift its bow.
now you only need to find out how to build one that uses aerodynamics to lift its stern, to roll starboard and to roll port before combining them to have a stable flight.

and yep you grids form has a big impact on how the grid flies with aerodynamics in your world.
DraygoKorvan  [author] Jul 27 @ 6:08pm 
Build your ship better or you can disable the advanced simulation in options (under physics)
MrMayhem Jul 27 @ 3:09pm 
Is there anyway to disable the part where the it forces the nose of the plane up well flying? I have tried in the appdata folder but still cant seem to straiten that out part out.
MarciXeN Jul 25 @ 1:56am 
I've seen online that this mod might affect how wind turbines work. Does it actually and if so then how exactly? I'm completely stuck on a new world with IO and the smelter needing 2mW of power and my turbines refusing to produce more than 100kW each with strong winds (over 1m/s)
@Paradoxon360
does it happen with just aerodynmaics and requirements in a fresh world too?
if not its probably something that happens in a specific modcombination.
Paradoxon360 Jul 14 @ 4:58am 
the game crashes if the heat of an rentry is destroying blocks game frezzes crash no the deadly rentry isnt working for me ...

is there spezial limits configs maybe its becouse of to mitch sparks i dont know
Harold Jun 23 @ 9:36pm 
The deadly reentry is awesome. Just blew up my ship in a splash of sparks. 10/10
Abisius Xarvenius Carbensius Jun 18 @ 10:35pm 
@Малигос
the blueprint scren shouldnt even open if you open the admin menu and it doesnt open on my end, so if that happens i would say its something irregular that happens there.
AK-74m Jun 18 @ 6:57pm 
nvm just alt+f10 oops
AK-74m Jun 18 @ 6:55pm 
i was at work and had access to the console and files from my phone... the shift+alt+f10 menu is kinda weird too with the admin mod menu, the blueprint screen blocks the view, can't even make it transparent in the options, i'll check in that file directory, thank you!
@Малигос
so you manage a server without having access to se itself to join it as an admin to be able to check in on stuff and access settings made to be accessible from in world?

if that is the case i would recommend from my side that you either get a version of se you can use for it or get someone you trust to do that stuff for you.

besides that the file with the settings of the world are inside the world specific storage folder findeable under %appdata%\spaceengineersdedicated\saves\yourworldname\storage\571920453.sbm_sedrag but you might need to request access to it if you use a third party serverprovider as most of them dont allow access to the appdata area on default.
AK-74m Jun 18 @ 1:43pm 
Is there a way to change the max speed in the configs? Im running a dedicated server so its kinda hard to press buttons to open a menu
DraygoKorvan  [author] Jun 16 @ 9:47am 
It can Confuoco, as Ryunoske states though if you are using large grid this mod does not do the lift calculation by default, there is an addon mod that enables those functions here: https://steamcommunity.com/sharedfiles/filedetails/?id=2800215762
Ryunoske Jun 14 @ 2:10am 
Hello, sorry, we had a talk here. Closed shape will do nothing, and if you are speaking about large grid - drag coefficients don't work, so any ship is a brick for this mod.
Multiple wings I think will work, but I suggest just trying it and comparing.
Confuoco Jun 13 @ 5:57pm 
Hello. Question:
Does multiple layers of sloopes (wings) will help with lift? like multiwings?
Ryunoske Jun 13 @ 1:05pm 
Everything can be an insult, eh? :steammocking:
Confuoco Jun 13 @ 8:02am 
I want to build super ugly simple cargo plane. And was thinking how many minimal thrusts i need to be able lift off.
and second is worth additional 'profile' to keep closed shape that additional mass or get rid it :)
@Confuoco
i usually go with "does it look like it can fly with wings?" and if it looks like that is give it a trial and error tour till i find is ok how it flys.
