Fighting Constant right bank

[Fakum]

maybe its just my cougar? But for example, when I pitch the nose forward and set trim, I get a constant suttle right bank, if I let it go, she will just continue to roll, even with bank,pitch heading stabalizers on ? I have to keep pressure on the stick

[xxvintersorgxx]

it also trims your anti-torque pedals (rudder).. your bank pitch and roll.., have you watched the tutorial on how to trim ?

[RvETito]

No antitorque pedals exist on any coaxial helicopter. Right bank is normal, the upper rotor have twice the arm to the center of gravity. The trimmer is your friend. While you speed up the helicopter will have constant thendency to bank to the right. You can fly fully straight hands free if you trim it properly, in this case the cyclic will be deflected to the left and the right pedal should be pushed forward in quiet a range. All features.

Hi,

 

You get used to rolling left as you accelerate, and rolling right as you decelerate. It is quite noticeable if you trim only at the extremes of speed (0 km/h and 250 km/h).

 

Put the controls where the helicopter flies forward in level flight and maintains speed, check the rudder is central, then trim. You shuold find the controls are where they need to be then. If the torque pedals are *not* centralized when you trim, then you might find you have additional roll input to counter it, or are even side-slipping slightly.

 

Best regards,

Tango.

Turn off the flight director Ctrl+A and fly that bird by hand its much easier! I don't trim at all, no need to when Im the one flying it. I only turn it on when I need to hover now and Im enjoying it 100% more..

You mean when you manually hover then?

 

Flight director namely won't work with auto-hover.

Can you go into Foxy / joystick analyzer and see if it the joystick centers to the right a bit(?).

[Weta43]

I think he meant turn on the flight director & fly by hand, turn off the flight director to hover...

 

Or trim ...

Ahhhh, the upper rotor is farther up the mast and away from CG; hence the slight right bank in the coaxial helicopter....

 

I was a little puzzled why a coaxial would have the same tendancy as a single rotor heli....now i know...

 

Thanks AirTito!!

Thanks for the info guys, I thought I was having a problem with my Cougar, although using the Foxy Analizer indicated dead center, it left me scratching my head. So, the bottom line is, When I have the trim indicater up (to view the diamond) it wont be unusual for me once I push the cyclic forward keep her level, rudder centered and THEN set the trim, to see the diamond up in the upper left section of the grid, correct? If so, I guess because I was setting the trim keeping the diamond dead centere hardware issue.d on the vertical line, and she is rolling right, I thought I had a hardware issue.

[slug88]

Yes, for stable forward flight, the diamond should be in the upper left.

Boy,,, I still have some hair on my head after scratching it so much. thanks for that key note. I have done more reading then flying,,, theres alot of meat here. I have also watched the producers notes many times as well,,, I will have to find this "Trim Tutorial" xxvintersorgxx speaks of. Maybe I overlooked the obviouse? All i have been doing is practicing startups and hovering and trim. improving on all over time, then I will move onto the next phase,,, thanks

Anyone know if the Flight Model can be edited? ... perhaps one of those .lua files?

[Reticuli]

Eeeks! I wouldn't recommend it even if you could. Ever seen even EECH's flight model code? Without the explainations for what everything does and the detailed relationships...yowzers. One tweak and it goes from a very good flight model (that may seem a little too unforgiving at times to us laymen) to total chaos. Know when to be content with near perfection. The house of cards is stacked and looking pretty good. That 6 of clubs doesn't want you touching it way down there at the bottom.

Surely the whole point of BS is the flight modal? :unsure:

Here's a Video tut http://www.digitalcombatsimulator.com

 

Just go to the Files/video section, producers note 10, page 1 I believe :)

Hi,

 

While not completely new here, I had to re-register because -obviously- old lockon.ru logins wont't work.

 

I bought BS about 20 days ago and I must say I am highly impressed with the flight modeling.

 

That said, most people here seem to think in terms of fixed wing aircraft which were featured in lockon.

 

So let us get some things straight:

 

Most of you are familiar with the term "Angle of Attack (AoA)" of an airfoil. You know what it does, you flew lockon and maybe countless other sims.

 

As you are aware, the greater the angle of attack, the more lift a rotor blade (practically a wing) generates and more power is required to drive it through the air at a given speed, because of drag. All your controls work by changing the pitch angle of the rotor blades.

 

If the rotor was operating in motionless air, pitch you command with the cyclic and AoA would be the same in value. But, this is only true when the rotor spools up. Once the rotor is spinning, it creates a constant downwash through the rotor "dish".

 

If there's an air current through your rotor disc, as when hovering or moving over the ground, this also changes the effective AoA of the rotor blades.

 

The half of the rotor disk that is moving forward into the wind, has a higher AoA and higher airspeed than the retreating half. This means, if you picture it from above, that the rotor generates more lift on the advancing than on the retreating side.

 

So, your aircraft has the tendency to roll to the side that is generating less lift.

 

Enjoy flying a helo for what it is :)

Thanks Axel40, but as I mentioned, I have watched producers note 10. I thought there was something else out there called "Trim Tutorial". Notice in Producers note 10 there is no mention at all about the natural right banking of the aircraft, which requires you to set the pitch left as well as forward when you want to move forward at say a 10 degree pitch. Also not shown is how to trim before you engage hover mode, of hovering in general.
