Why does the plane do that?
Is there a particular reason?
The cross wind component of the wind at the airport causes this. Use rudder to correct on takeoff roll.

If you are flying a single engine prop like the C152 the rotation of the propeller will cause it to yaw in the runway and in the air. If you fly the C152 by DR on a course you have to keep correcting it. This is authentic, apparently.
and it happens not only for the propeller engines but also for turbine engines too.

It’s from torque. “P-factor” is what you want to study if you want to learn more.
Not really. You can have zero wind and a prop driven airplane will still torque to the left (or right…depending on the direction the prop spins) which needs to be corrected with rudder. That’s why a prop-driven airplane goes left or right when taking off.
Add a second engine spinning in the opposite direction and it will cancel out the torque. Add a second engine that spins in the same direction (as many do) and you’ll be pushing on the rudder even harder.

OP said the plane (as in singular) goes left or right ie. both directions. Also later said jets too, so crosswind is more likely causing the veering. Either way, rudder is the solution.
I get the same thing, but its with the airliners, i always thought it was a tailstrike.
It happens to me too. I have been using flight sims for more than 10 years. In my case, the plane (turbine, prop, jet) starts rolling and when it reaches a decent amount of speed on the ground, it decides to make strong turns left and then right. When I want to correct it, I feel like the game is multiplying my input rudder by 10, making the plane turn the opposite way and making it look like if I were playing a drifting racing game. It is not normal to me, no wind could make my plane react that way. I enabled rudder assistance. It is now reduced a lot, but it is still there.

Not exactly. He wrote, “and it happens not only for the propeller engines but also for turbine engines too.”
“Turbine” doesn’t always equate to jet. There are plenty of turboprops out there which also must abide by the laws of p-factor.
Same with me! But only after the last update for my Pitts…
Before, the effect was noticeable, but with decend rudder you could handle it – Now you feel like a “leaf in the wind”
i know of p-factor and wind, as you said it, but what the game does has nothing to do with it, it’s just bugging out about trying to simulate this effect, my guess. Even at 0kts with a two prop aircraft it tends to wiggle to either side, and no matter the sensitivity of the rudder/pedals it can be impossible to keep it stright, to the point where vatsim controller asked if i want to declare an emergency or abort takeoff.

Hello my friend. Well, I am real pilot, maybe I can give you some input there. It is true that the aircraft will always have some tendency, most of the times the yaw tendency is to the left, making you need right pedal input on take off. Another situation where you notice that clearly is when you do a power on stall. The tendency of the aircraft will be to roll to the left as it stalls, because of the P-Factor, just like on take off.
Now, about the “uncontrollable” pedal on take off, that is not a simulator problem. The pedals controls can be very very tricky on take off and landings, especially with cross winds and/or tail draggers. So no, the simulator is not very very hard and impossible to control. Actually, in real life, sometimes it is even more difficult then what the simulator gives us, especially with tail draggers (they are a bit too estabilized at this moment, on the simulator).
Making it short: it is hard to hold the center line for beginners. You need a lot of practice and you need to learn how to “wear” the aircraft, as if it were an extension of your body. It takes some practice. It is also important to always give elevator input during the run, as in real life you can’t just put power on and wait enough speed for take off. You need a lot of simultaneous inputs. That’s why most of the incidents with aircraft happen during t/o or landings. Those are the most difficult and delicate parts of the flight.
I think the problem might be on the “game” noun you used. This is a game if you use it like that, but it is also a simulator (in progress, we all know that LOL). It is not supposed to be like a game, unless you turn all the settings to easy mode. So, in that sense, it is supposed to be hard, isn’t it? =)
I use the term jokingly condescendingly. it is not about “hard” and “simulation” it is the fact it is or at least become, now even more then ever: a game.
Oh, I get you now. English is not my first language so sometimes I might not fully understand subtle comments. I’ve been hard on Asobo and Microsoft before because they have broken the sim many times. But I also always make compliments because what they have achieved (with black shard aswell) , no other simulator did (and I have tried ALL OF THEM). I have more then 5000 hours on sims and their job is great, even with all the problems I don’t want to go back to X-plane, P3D or any other sim. I do agree that their attention to XBOX and the “game” bring problems to the sim aspect of it all. Aircraft not working properly being the main one. Let’s hope they keep on the good work and pay good attention to the sim aspects.
