@GrandmasterPotato oh that's actually a good solution I never thought of with the extra wheels, thanks!

@YourAverageAviator yes, if you are using resizable wheels, that is probably the issue. To get around it, try playing around with traction settings, and if all else fails, you can place tiny pieces of normal landing gear just below your wheels, and it should be fine.

@GrandmasterPotato Did you ever find the solution? I am having the same problem right now on my Ju-87 D-5.

@GrandmasterPotato
Alright, post me an unlisted link of it.

I have always been counter-steering softly, and I have tried everything you can really do with those values, increase one and decrease the other, reverse that, increased both and decreases both, nothing has worked. @ZeroWithSlashedO

@GrandmasterPotato
Don't countersteer harshly, countersteer softly.

And about the values, try lowering them.

I tried changing the values but it it still drifted out of control, even though I was trying to keep it on.
@ZeroWithSlashedO

@GrandmasterPotato
Huh.
Weird. Tried it before and it was fine...
Oh wait. Did I forget to mention that, that problem is unfixable?
Yeah no, You'll have to countersteer slightly in order to even stay straight on the runway.

Try changing the values of slipSidewaysExtremum and slipSidewaysAsymptote.

And that did not work @ZeroWithSlashedO

I would try it, but on mobile we do not have the option of physics settings @Bellcat

In the XML of the Resizable Wheel part, there are two things that may help you, which are:
slipSidewaysExtremum and slipSidewaysAsymptote.
Try playing around with those values.
However, if you don't want to go back and forth modifying these, I would suggest just putting the sidewaysTraction to 50%.

@GrandmasterPotato, just go to the settings and try to put the physics level to whatever suits you, like “high physics” if you want a more realistic physics. Note that Simpleplanes is a video game, not a physics simulator.

What do you mean?@Bellcat

Have you tried modifying physics?

I already tried that @TheFlightGuySP

@GrandmasterPotato That's probably the reason.
In my experience, resizable wheels drift at high speeds.
You may need to change some traction settings.

Yes @TheFlightGuySP

@GrandmasterPotato Does the aircraft use custom landing gear with resizable wheels?

Both of those are already done, and it still drifts. @Bellcat

@GrandmasterPotato, about that...

• try to check wing symmetry on the vertical stabilizer.

• don’t put turning on the front gears. Put turning on the tailwheel instead.

Thanks.

How to stop drifting apron takeoff?

Please clarify, I cannot yet understand the problem. From what I can tell is that the plane has attempted to drift off-course, which also happens in mine too, even on tricycle landing gear.
