First Impressions

[doebro2010]

allright there we go:

I was searching for the best settings in relation to my computer specs.

The one I got from Jcomm was not the one which is suiteteble for me.

In the meantime i will try to figure it out by trial and error.

Furthermore I have a problem to fly with the P51 although I have practiced a lot with the A2A.

If I setup a quick mission within DCS then the take off give me some problems.

The rudder is overreacting and a slight of a movement causes problems.

So i went to the controlsetting and try the rudder from 100% saturation to 50% but that didnot turn out well.

So still with take off the plane crashes immediately although I use 5% rudder etc.

ahhh ok.

 

P-51 takeoffs are never dull. Even with the optimal settings your feet will dance a few steps before you're in the air. Make sure to increase the manifold pressure smoothly to keep the toque effect manageable. After a while you will be able to predict the movement of the nose and correct accordingly with rudder input. If you have adjusted the axis tune and pre-set the 5 degrees of right rudder trim I'd say you just need to put in some time practicing it. Definitely not easy at first. Also keep a little back pressure on the stick to keep the tail wheel planted until around 100mph.

doebro2010,

 

I can only ask you not to give up... Been there, done that :-)

 

Comming from MSFS is not the best way to adapt to the requirements of DCS World, believe me... I also own the A2A p51d. Actually I re-installed FSX and bought it to compare with DCS's p51d... A2A did a great work, IMO the further it is possible to get using FSX's flight dynamics model. Now this falls short from what we get with DCS!

 

One thing you should bare in mind is the course of your joystick / rudder pedals (with the joystick presenting a bigger lapse...) compared to the real thing. If you imagine your joystick increased in length to the size of a p51d manche and try to map the amplitude of your inputs to that of the real thing, you'll start understanding why we're sometimes using exaggerate control inputs...

 

Try not to pull your manche to much during the takeoff roll, just a bit until you're just above 100. then let it go and concentrate on mantaining the aircraft aligned with the rw until it wants to fly. Use small but on-time corrections. If your rudder allows to adjust it's spring strenght, increase it to the max, or near it...

 

You can also try not to set max takeoff power of 61 inches but instead go firt through 40, then increase to 50, and perform your first takeoffs at 50+ inches only.

 

Make sure your RPM lever is at full fine (full ahead).

 

Practice, practice... practice... You'll get to the point where taking off and landing, even with 15 m/s (30 knot) crosswinds and max turbulence (factor 60) is perfectly doable :-)

One important thing during take offs in DCS P-51.

 

I dont know why but it is much easier to take off without using take off flaps. When i tried to take off with flaps plane became more unstable and swing stronger.

 

It was for me very suprising casue i fly IRL prop planes and small flaps always help me in take offs in all planes i have flown and dont casue any problems. Normally it should be easier to take off with flaps - shorter take off run, lower take off speed ( higher lift) etc.

 

I still wonder if IRL P-51 was soo tricky to take off with flaps - much more then without them?

 

Anyone have idea? Yo-Yo?

Using flaps causes a pitch down moment, and your tail will become "less heavy" too soon, raising before the speed where you have sufficient authority to control the airplane around it's vertical axis during the takeoff roll.

 

OTOH the downwash increases the slipstream effects and causes more yaw, and even more roll induced by it, so, the aircraft will require additional control inputs.

 

As far as I know flaps should only be used when the airplane is heavy or the fuselage tank filled (?)

 

Of course, I will also look fwd for Yo-Yo's explanation ;-)

[doebro2010]

thanks gentleman,

I will try again and practice

A last question referring to JCOMM

your rudder allows to adjust it's spring strenght, increase it to the max,

 

what do I have to set and where?

[Anatoli-Kagari9]

I have the Saitek Pro rudder pedals:

The center wheel is an adjustment for the spring force of the rudder. Not all rudder controllers have this option. I believe none of the CH has it (?)

[sobek]

The center wheel is an adjustment for the spring force of the rudder.

 

Not really the spring force as much as friction damping. It gives it a certain "molasses" feel.

Correct! ;-)

It's very simple - flaps make P-51 flyable at lower speed. As any plane. But they can not make it more stable and controllable against torque, P-factor, etc. That's why it was directed in manuals not to use flaps except the case of heavy loaded plane. Anyway, the Pony is silky if its faster than 70-80 mph (for me) so the flaps must be use regarding the TO speed about 105 mph.

 

The difference between P-51 and general aviation plane is in its power to wing/empennage area making prop effects much more noticable.

[Suchacz]

sometimes the plane makes a turn by using the rudder of 180 degrees

and this wonderfull aircraft goes on backwards.

Maybe you missed the part of the flight manual about a tail wheel lock...

[doebro2010]

No I know that but the problem was the automatic settings from dcs from my G940.

I changed the P51 but if I started to fly quick mission then it turned out I also had to change the P51 game .

So my rudders were the problem by these.

[Irregular programming]

It's really confusing that rudder assist is set to on by default.

 

 

Logically you should turn on the assist if you need it, not the other way around.
