Take Off config 1.1.2.1 beta

[26-J39]

as you see in the Trk the plane will not keep straight. If I even apply very light pressure on my rudder to correct right. the plane lurches to the left. All axsis are correct.

 

Yes that's normal. :music_whistling: Besides all the trim and tail wheel talk, as I stated, you need to anticipate the a/c lurching to the left and counter with appropriate opposite rudder, not "very light pressure".

 

I watched your trk again and paid close attention to your rudder inputs and yes you did not apply enough counter rudder as it lurched left.

 

Good practice is just to start on runway, run her up, don't touch the stick! & just keep her straight on the runway. When shes ready to fly u'll know.

Point being concentrate on ur pedals, once you got that.... trim/tail wheel blah.. Don't matter so much :)

Also get a reference point to look at during takeoff, And stick to it.

Again if the plane is too twitcy then play around with your curvature settings.

 

Guys with problems what joysticks do u have ?

That is SO important. That one thing made the difference between the fireballs in the grass and the drunk taking off. I may weave a good bit but my pilot lives.

 

I sight in on a spot in a cloud ahead of the runway and only glance at the instruments. I don't even think about the stick, which can cause a slight issue, but I have to concentrate on the rudder the whole time or I am in the weeds for sure. Now if I could only see about 2 seconds ahead in time I would be rockin'.:D

 

You almost have to be on the rudder right before a shift in direction begins.

Spot on :thumbup: That's where practice & patience come to play, knowing what that beast is gonna wanna do. :)

Heres something that bugs me. Being an aircraft mechanic, I know that green flag tells me something, and that means I really shouldnt be revving the engine up past that green line. That engine cranks out over 1200bhp without the turbosupercharger, you dont need that much power to get airborne. Im still learning how to take off (which pisses me off too, but at least Im trying...), but I know that if you have that much power going to the prop, you are going to have a lot of torque, and its going to try to roll you in the opposite direction the prop turns.

 

As a matter of fact, as of now I have my first takeoff! Heres the track on how its done, recorded no more than 3 minutes from this post.

Nice takeoff hitman.. Well done :smilewink:

[hitman]

Yup...I come home from building airplanes, I get home and fly pretend airplanes. I went to the airplane restaraunt in colorado springs last weekend. Im pretty sure I pooped airplanes that night as well. I think I need to get laid. =\

The green line represents "normal operating range", which in this case, is the range of permissible cruise power settings. Just compare it to the charts. Maximum continuous power is 46" and 2700 RPM. As long as you don't exceed that, you shouldn't ever feel guilty! (Okay, maybe just a little...)

 

As far as realistic takeoff procedure goes, here is the relevant section from the P-51 Pilot Training Manual:

 

REMEMBER: Avoid sudden bursts of power in the takeoff. Make it smooth and steady.

 

After you have pulled out and lined up on the runway, make sure that the steerable tail-wheel is locked - it must be locked with the stick back for takeoff.

Then advance the throttle, gradually and smoothly, to 61" of manifold and 3000 rpm. Don't hoist the tail up by pushing forward on the stick until you have sufficient airspeed to give you effective rudder control.

This is important to watch in the takeoff, since the P-51, like all single-engine planes, has a tendency to turn left because of torque. If you horse the tail off the ground too quickly with the elevators, better be ready to use right rudder promptly.

Keep the airplane in a 3-point attitude until you have plenty of airspeed. In a normal take-off, the rudder trim tab is sufficient to make the torque almost unnoticeable...

 

Caution: Don't brake the wheels after takeoff. Doing so may fuse the discs of brakes that are hot from extended taxiing. If this happens you'll nose up or groundloop on landing.

 

So, going to full military power is S.O.P. How long you take to get there is determined by how well you can control the aircraft on your takeoff roll (and the length of runway available.) The in-sim training does recommend using 50" for a while, until you get used to the torque.

 

Ignore the final reference about the brakes. I just like to throw in little details when talking about these sorts of things.

 

Anyway, congratulations on your first takeoff, Hitman! You can only improve from there. I have not watched your track yet, but I just want to encourage you to keep at it. It's absolutely possible to do it by the book, given enough practice. The one exception I currently use is a reduction in rudder trim to compensate for the way it is implemented in the sim.

 

By the way, what did you order at the restaurant? Rudder cable spaghetti? :smilewink:

[LcSummers]

Your tailwheel is locked at neutral- no need to pull the stick back, unless you have unlocked it and are attempting to lock it again.

 

 

 

 

I am a bit confused. So if a made a touchdown, landing do i have to pull back the stick or not?:joystick:

No. Land, rudder for taxi, done.

[LcSummers]

Oh thanks, makes it much easier. So i will give it a try.

 

S!!!

[hitman]

All you really have to do while landing is idle the engine down and go low pitch on the propeller. You WILL have to pull back on the stick eventually, since its a tail dragger, and braking will cause the tail to come off the deck, and youll want to keep the tail on the ground to prevent a prop strike. But you should only pull up on the stick after you brake on the ground AND ONLY THEN when the nose starts to come down.

Landing is going quite well, i mean shortly after touchdown and then taxiing

[hitman]

Landing, and landing in one piece are two different monsters altogether. Youll still want to keep the prop from striking the deck, and that pertains to both takeoff, taxiing, and landing. You can be taxiing at 5mph, get a gust of wind, and have the tail section lift off the ground and cause a prop strike.

Ahh... yeah when you apply the brakes to hard, other wise NOT. There is no reason why a good pilot would

allow this to happen.. ;)

Thanks guys, now its much clearer.

You are reading the wrong manual. I honestly do not know where to start explaining where you went wrong, but I'll try:

 

OK, spawn into the cockpit and leave all your trim wheels alone - aileron and elevator trim are fine at default. Start up and taxi to runway - no need to stand on the brakes in an attempt to steer as your tailwheel was locked the entire time - use the 6 degree steer to runway. Remember that the tailwheel is only unlocked forward of neutral: At neutral it is still locked.

 

Once on RW, input about 5 degrees of right rudder trim. Now slowly advance the throttle to 42-45 inHg and leave it there. Keep the aircraft aligned with rudder input only and after a while you'll feel the tail start bouncing and the plane feel light. Slight back pressure on the stick and she'll fly herself off the runway in a three-point attitude as per this post/vid:

 

Man.. :( All the lousy girls I knew their name is Sally... I guess we're not built for eachother...:smilewink:

[WildFire]

Well I havent watched the track but I'll take a stab. There is a condition where you lift off and for a second or two it looks good. After that second she begins to roll left and basically throws herself into the ground. As she is doing this any type of control has zero effect.

 

I read a flight journal while I was in the navy that talked about props having problems getting off the deck in this way. If your talking about the plane darting off to the left in midair then its pretty simple and the same problem they were having. Basically its a stall. Im sure most people already know that. And its really easy to do with props cause your trying so hard to get it off they ground that you dont give it enough time to get speed. Its a specific type of stall and I'm sure somebody will come around and answer and say what it is.

 

However if your talking about darting on the runway while still wheels down, see my post here;

http://forums.eagle.ru/showthread.php?t=89267

Chances are you aren't controlling the ball properly or your rudder is messed up. I figure the ladder since people are watching the track and citing that. Keep in mind if you dont have rudder pedals this plane is going to be near impossible to take off with take off assist disabled. She's pretty hard with pedals, let alone trying to use a stick or keyboard.

 

Most people cited trim like mine, its pretty much user preference however I would strongly advise a click or two right aileron (roll). When she first takes off if your at low speed the stall condition exists. At this moment the plane will lose lift and the torque of the motor will spin the aircraft left and right into the ground. Remember once this begins, it is already too late. Many pilots have died this way. However setting your trim to roll right will help stop this tendency and it also helps keep the plane stable for that extra second or two that she needs to pick up speed and overcome this potential stall condition. On the other hand you would have to set some pretty severe right roll trim to get her to overcome the torque effect and roll right. Its almost unheard of to have a stall on the opposite side of the torque effect on take off, its always to the torque side. So basically what I am trying to say is that you have more to gain than to lose just by setting some right roll for safety.

does it matter? I still no matter what curves I set, what sensitivity is set, the same issue. the bouncing rudder ball swings wildly to the left and right just barley moving it.

 

SO I gave up and just do air starts.

Sounds like a bad pot issue on your rudder :(

 

test it in windows and see if it spikes. If it does, time to clean or replace pots if possible.

 

Spikes in the pots: if its only around the neutral position, then add deadzone to skip the area where the spike happens.

If it's have all over the range of the axis and is very erratic then no game or software setting will help much :( replace pots.

 

What rudders are you using and how old are they ? (doh saw the make and model in your sig) If rudders are within warranty, talk to saitek about the problem if it is bad pots.

[71st_Mastiff]

nope clean as can be works great in all the other sims but this one and I watch the slip-ball just will not settle at all some times.

 

but in an air start works with no problems only when on the ground.
