As many if my fellow propeller airplane builders have noticed, sometimes your plane may have a roll to the left or right. This, believe it or not, is actually realistic. When objects (propellers, for example) turn at high speeds, it creates torque and so forth - meaning that your plane is slightly turning as the propeller gets more speed. It's more noticeable at 100% throttle, as your propeller has more going on. Now, if you have a dual prop airplane, it cancels out from the propellers turning in different directions.
this is also the reason that aircraft carrier islands are on the right side of the ship
It happens in real life, but I'm pretty sure it's just a glitch tho. If it was intentional things like helicopters would need to have a functional tail rotor to stay stable but the propellor doesn't torque the helicopter around like it would in real life. You're totally right that it happens in real life, it's just the SP physics simulation isn't that in-depth
PAST is a good acronym to remember this...[Gyroscopic] Precession, Asymmetric Thrust [P-Factor], Spiraling Slipstream and Torque...only occurs in prop aircraft. Real aircraft experience this and it's most pronounced at high power settings and low airspeeds due to high thrust aggravating all of those PAST factors and a low airspeed making the flight controls less effective...at the worst possible time, low and slow. That's why pilots of powerful single-engine prop aircraft, such as most WWII fighters, add a bootful of rudder when applying power, especially on takeoff. When the aircraft are flying faster, the empennage and a little rudder trim take care of trimming out the aircraft to stay straight (@Tully201). Unfortunately, in SP, this is NOT what causes the rolling we've all experienced. It's caused by this; there are ways of fixing this, usually by replacing the offending parts on the aircraft and avoiding causing the problem in the first place (@AudioDud3).
@EternalDarkness Yes, that is.
I knew about the propeller torque. But a plane with two jet engines shouldn't be doing that. It's a drag glitch
I suprisied how many people don't know this
