After reading most of posts here, I would like to thank you for explaining how to take off and land. I would also like to add my tips for take off. Landing is a bit tricky for me as I don't have toe brake and I can't help her to skid at the end of the run. So here it goes.
For take off, I first make sure that I have lined up with runway with tail lock by slowly running the runway for a while. At this speed, I can play with the left and right brake to line up with the runway and get the feeling whether I have a proper tail lock. I then increase my throttle slowly and push my joystick to the center in synchronization with throttle and then as others said, my plane is on air by itself. A minute and constant adjustment with rudder after 100 km always helps as well. With this method, I have been successful about 95% of times. I hope that this helps someone as I got help from many of you.
Best,
