Ground loops can happen on take off also. Depending on the aircraft, you
have to use the rudder to keep yourself tracking down the runway, a smooth
application of power at the start of the take off roll will help too. Hint, all the
single engine aircraft need right rudder to stay on the runway, except the
IL-2. It needs left rudder, prop rotation is counter clockwise.
On landing, once you are on the ground and have slowed down a little,
hold full back pressure on the stick, this forces the tail down and locks the
tail wheel. Watch out though, if you are too fast, you will go back up, then
stall and crash.
