Thanks for answers. I tried to lock tail wheel, regulate rudder, start engine with low engine power, but it doesn't work too. If I regulate rudder a little bit to right side, then my plane starts turning right. Is this shit happens to all of you too? Thanks.

P.S - Sorry for my english.

It happened to the pilots of real aeroplanes too. In the fifties a race between two spitfires was organised at a Farnborough airshow. Both aircraft would compete from a standing start and finish on that line in front of a crowd that included many senior officers.

Eager to make a good impression, win the race, and being young competitive individuals, both pilots on the start of the race immediately whacked open the throttles. As a result both spitfires swung ninety degrees off the runway direction and taxiied quickly toward the crowd who understandably scattered very quickly!

On a video of Kermit Weeks original condition MkXVI Spit, I noticed the american pilot had an interesting take off technique. Concious that his rudder would be ineffective at low speed (which is why it's hard to control direction at first - notice that at around 60-70 kmph your simulated fighter will suddenly straighten out for gameplay reasons) he simply rammed the throttle open with full rudder and raised the tail there and then. I wouldn't personally reccomend doing that but I guess he knows the aeroplane.

You see, there's two reasons an aeroplane like a MkXVI Spit will swing or swerve on takeoff. Firstly, engine torque, but also gyroscopic precession as the axis of the rotating engine is changed when the tail is raised. They're both suprisingly powerful forces.

I also recall a story about a mosquito squadron who'd suffered a large number of take-off accidents due to aircraft groundlooping (swinging so much it revolves around out of control). The exasperrated C.O. summoned his pilots for a right old telling off. "The Mosquito doesn't swing!" He harangued them, "Only you silly b*****s make them swing!" The accident rate rapidly declined.

Practice, practice, practice. These forces smashed up a lot of aeroplanes in real life. I would suggest moving the throttle slowly, it does help, but you should realise that some of the aeroplanes in the sim (the Pe2 was notorious for lack of directional stability on the ground in real life) are worse than others. Learn which way the aeroplane swings on take off. At first, it will wander in that direction, then it will swing back with a vengeance, so stay alert on the rudder. Tailwheel aircraft demand quick reactions on the rudder bar and the sim does so too.

PS - I've just realised - it might be the wind that forcing your aeroplane to weathercock. It gets a bit over the top sometimes. Try turning off the wind in your difficulty settings.
