Rudder on takeoff...

[Socket7]

I guess since practice is definitely what fixed it, then the bug was a result of bitrot in archival storage for brain.exe :doh:

 

One of these days I'll be able to install a hard drive in my head, and my memory will stop playing tricks on me.

Interesting topic indeed.

 

I have came across that experience with all of the DCS modules, p51d, fw190 and the K4.

 

They all presented problems the first time I took off or landed. Landings were my biggest problem when I started using the p51d in 2012. I almost always experienced ground loops...

 

With experience / training, they're all piece of cake :)

 

But, it's not only, in my case that's actually the less important factor, the way I input my stick and rudder corrections, but rather the way I use power on takeoff...

 

I slooooowly advance the throttle in the P51d. I never took off againg at more than 1,4 ATA in the K4, and I never tried to land on two wheels again in the Fw190....

I had a go at it again after not touching the plane for over a year. No trouble. Ha. Practice is a funny thing even if it's on another plane.

It is funny looking back when I first tried the P-51. Thought to myself, this can't be right. All of that was due to not understanding how the machine works / needs and having it easy in previous sims. Nowadays for me the P-51 is easiest to TO, even when powering up to 61" from the get go. Same applies to landings.

That is probably the best suggestion as far as TO goes. Try TO at a steady power and suddenly it becomes much easier. Sudden power changes require sudden directional control adjustments. If you are unused to them, the end result is obvious.

In my experience, this is of paramount importance in any hi-perf prop plane. And I'd even say that if you DON'T do it, it suddendly becomes impossible ;) Never, ever ram the throttle, but always advance it slowly. These are the words to live by!

[Echo38]

Hmm. I always advance it as quickly as I can without risking the engine--so, smoothly over about two seconds. Lately I've been even holding it with the brakes, although if you don't let go when it reaches a certain amount of power, it'll overcome them and pivot left. I don't doubt that it's more difficult to do it this way, but it's still doable--with a full rear tank, even. (Both take-off assistance and auto-rudder off, of course.) As others said, practice!

For what, opening the throttle rapidly? No need m'man ;) Although slow would in my case be about 5 seconds or thereabouts.

[Echo38]

Heh--I meant that, with practice, things which were possible will become easy, and things that were impossible will become possible ("possible," not necessarily "advisable").

 

If you can handle the prop effects, however, you can become airborne quicker (with less runway used) if you shove it forward briskly. This is why I try to practice takeoffs with as rapid of a throttle-up as I can make without risking the engine.

I found this paragraph of the manual particularly helpful:

 

"It is recommended that 61 in.Hg and 3000 RPM be used for takeoffs and that this power setting is reached as quickly as possible after the takeoff run is started. However, advance the throttle smoothly and never jam it forward. Torque effects appearing from a sudden onset of power can lead to a loss of directional control of the aircraft."

 

Don't slam the throttle forward but do move it forward "quickly as possible". That way you aren't still making throttle changes as you raise the tail. On the P-51 and Dora I try to be at full power before centering the stick. It makes for a very smooth takeoff.
