What Minn says is true ... my tail draggers all take off differently, e.g. :

Black Horse SU31 (40) - does not pull much to one side when I throttle up, no need to hold any up ele, when the tail starts to lift you give some up ele and she will take off like a trainer

Black Horse Extra 300 (60) - does not pull much to one side when I throttle up, no need to hold any up ele, when the tail starts to lift you give some up ele and she will take off like a trainer

WM Rambler 40 - needs a little up ele to keep her nose from toppling over, then as speed picks up you release a little so that she will not 'jump' into the air and then add more up ele for her to lift off

Modeltech Raven (40) - does not pull much to one side when I throttle up, no need to hold any up ele, when the tail starts to lift you give some up ele and she will take off like a trainer

Modeltech Magic Extra - lifts off by itself but needs a little rudder correction

Phoenix Scanner (tricycle) - needs correction on the rudder if yo throttle up too fast

Maybe its how fast we throttle up, that causes the plane to pull to one side even more.
