Aircraft drifts to left on takeoff

[SaltyDog]

Hi,

With the latest and greatest updated Cessna C-310, I noticed that the aircraft wants to drift to the left on takeoff. I have tried other unrelated aircraft and
they all will not drift but rather takeoff in a straight line. I have my P3D V3.4 controls setting set to easy. I use a logitech 3D pro joystick.
The weather in P3d is set to calm. I am in Win 7 64 Bit. Just want to state what I can remember to mention before I get a did you try this or did you try that.....

Again, all other aircraft will not drift (left) on takeoff like The Cessna C-310 = Using update V4.170727 -

Thanks



EDIT: Breaking News! I reverted to the older version and I get the same effect - Drift to the left on TO. I read the known issues by Ken Stallings (SP?) and it mentions
something about the torque p-effect on takeoff - Is this addressing the drift on takeoff?

Salty, this is a known EFFECT of having two engines rotating the same direction.

Maybe, but after I am airborne, wheels up and climbing, the plane even drifts to the left unless I twist the stick to counter this pull to the left.

It's almost as thought one engine is overpowering the other. I just don't understand .....

Ya know...it's kinda strange that my aerosoft PBY will take off in straight line, I have another C-310 (Freeware) that was done by a Robert Richardson

scroll down a little to find the C-310:

Although not as nicely done as the MV version, His C-310 will taxi and fly in a straight line.

just saying......

This C310R is based on the real life aircraft of Ken Stallings, who kindly lent his expertise to this project. He assures us that the flight dynamics reflect the performance of his aircraft. Crank in a bit of rudder trim to counteract the torque, as he does in the real aircraft.

Folks demand realism... just saying!

Thanks. Can't tell what real is as I don't fly nor own real airplane - Guess if I owned the real thing then I would know.

10-4...

This is one of the reasons some schools use this plane to train for engine out behavior. It's sudden and can kill you if you're not paying attention.

One way to counter the pull to the left was for me to adjust controls. See attached. When I pulled back on levers (Yellows arrows) I could get the bird to not only to in a straight line, it would not
drift to left. I do here your explanation of real life twin engine physics, and I do appreciate the info on this; In real life I have been a pax in many real Navy or Air Force transports/helos, to be in the front
seat of a muti engine aircraft is a horse of a different color to say the least

With other twin or multi engineered aircraft modeled by Brand X/Y/Z, They claim they strive for the realism too; I guess they forgot to add the physics of torque whereby their aircraft will
drift (Like a car needing a front end alignment) down the runway and continue to drift during TO and after becoming fully airborne. I guess I have become spoiled to the fact that with the other
aircraft I fly in flightsim that they just cruise on down the centerline of the runway - Never pulling left nor right.

I know in P3D V3.4 the default Iris Raptor, when it comes up in cockpit view, on take off and in cockpit view, I sight thru the HUD and notice that the thing will not drift (two jet engines) one way or another.
I have become accustomed to no drift take offs like that and so when I try my hand at a TO in this C-310, I noticed a drift and think that somethings wrong with settings in P3D or my JoyStick is messed
up or something in the software, only to find out that this was baked into the MDL.

Thanks again.

I'm happy to learn that you've discovered differential power as one workable solution. Personally I've found that cranking a few degrees of right trim on the rudder works well also.

In other words, on take off stepping on the right rudder to keep the aircraft moving along the centerline, then cranking in a bit of right rudder trim to counteract the torque and yaw just as you would use elevator trim to reduce forces on the control yoke.

I'm trimming two clicks to the right. I think the flightmodel is one of the best for MSFS-based aircraft.

Just for the record, jet engines do not actually generate much - if any! - torque...
