I don't think the take-off difficulty is realistic.

So, before this escalates into something nasty, as heralded by the first reply to this thread, should smooth-takeoff-disbelievers consider that if some of us can do it, then it is possible?

    What I can add to this is that the statement about opening the throttle gently is a little inaccurate. You have to open it dead slowly so engine torque does not throw you hard to the left before you gain any rudder authority. If you do that, and if you have your tailwheel locked, it's much easier than the spitfire. No toe brakes, no dancing on the pedals. Easy

    Yeah.. but it doesn't match reality..

      Or.. "Above 550km/h, one peculiarity is a SLIGHT NOSE-DOWN trim change as you accelerate. This means that when you run in for an airshow above 500km/h, the airplane has a SLIGHT tucking sensation - a sort of desire to get DOWN to ground level." And a lot more like these..
      Tell me where and when do you notice any of these in DCS.. since you brought it up.

      He was talking about the takeoff.. you know.. the bit that this thread is about. All that 500kph flight business is for another thread.
      Leave the goalposts where they are.

        All i will say is that engine torque is defo a factor in most warbirds, most warbirds also dont take off from full power static when they have a tail wheel due to said torque effect, when the tail is down it is less effective, true however there are various techniques for this, a modern spitfire pilot managed to crash one after he used too much brake with too high power on take off and nosed over, while a lot of pilots tend to land with the tail slightly low of level for a wheeler, yet the manual states 3 pointers if i recall correct.

        as for aliaron being inneffective sure, it might be less effective then at higher speeds however i can say from experiance that you can still wing scrape by using aliarons, i had a rearwin up on one wheel at 40mph due to wind picking up the wing, it took near to full aliaron to counter it.

        Another point is the method for taking off and landing, short take offs such as in a mustang are from a 3 point attitude and i believe it describes this in the manual, it also states to be cautious due to the torque and less effective controls. the second way is by raising the tail and then letting the aircraft fly off the runway which from what i have seen is the prefered way of taking most taildraggers off. the sketch part of this is the transition between tail down and tail up as the controls will require changes and as such over correction can occure.

        another point about using high power on take offs is engine cooling, it is very easy too cook a merlin or db if you have the radiators closed while at high power, a 109 pilot damaged their engine and ended up in a field due to having closed radiators and overshooting the runway.

        as others have pointed out with the spitfire thread this pandaros box, every aircraft behaves differently for every player with every control setup. i would say its generally about right, he said he hasnt flown it in a while, he might have control reset, nostalgic memory or something else.

        all i'd suggest is lock the tailwheel, stick back, gradual increase to 1.4 ata, use a small amount of brake in jabs at lower speed the same as you would the rudder, then as the rudder becomes more effective, stick forwards, use more rudder to counter the swing, increase power and your off once you get the speed.

          Indeed. This is more of a factor than people realize, or are willing to admit. And hence all the whining about how everything is incorrectly modelled. Seen this in all the CFSs I've ever flown, and both sides are equally guilty of it.

            The ground handling of these aircraft was so hairy it was damn near legendary.

            Tiny, lightweight plane. Whopping powerful engine, and huge propeller. Narrow-track, taildragger landing gear that gives the ground handling properties of a three-legged ass that's had a few too many beers. Oh yeah, you can't see anything in front of you on the ground, either.

            Many young pilots were killed just trying to learn how to take off and land these metal monsters. World War 2 wasn't all guts and glory, a good portion of fatalities were attributed to young people just trying to learn to fly an airplane type that no young inexperienced pilot has any business trying to fly in any situation except a desperate, all-out war.

            Never flown before? Hell, never seen an airplane before? No problem, here's a little introductory course, and now we'll put you in the seat of an 1800 horsepower fighter. Good luck!

                Bf-109 well known feature is that tail vertical stabilizer is very small compare to other planes but the tail is significant longer.
                This makes two things,
                First it is hard to control at low speeds
                Second because of the long tail rudder is quite effective at Yawing plane left right so pilot can easy bring aim to make a shoot even if nose is quite off the target left/right

                  You're contradicting yourself.. and the rudder is large enough for yawing the plane, even at low speeds, but in reality.

                    I'm not, at high speeds small rudder is no problem, but long tail change plane behavior compare to one with short tail and bigger rudder surface..

                      Watch this, 1 take off 2 points of view.
                      From outside take off looks smooth, but once you jump in cockpit you will see how much this bf-109 drifted to the left during take off it got nasty left swing just before lift off, and this pilot used i think 1.2ATA
                      Start watching from 1:30 is you don't want to look at bf-109 start up.

                      If you watch closely couple of moments after tail lift of what is happening with the plane, DCS bf109 act very similar to this real one.
