<div style="text-align: left"><span style="font-family: Arial"><span style="font-size: larger">Iam having trouble making a straight takeoff and am considering several possibilities and I would like some advice. Typically, the plane upon rotation will make a 30 degree turn away from the field staging area. I am considering using slight use of rudder to correct for it. There is the possibility that I am inadvertently causing the problem by either a slight misapplication of rudder during throttle applcation or a slight use of aileron during elevator application. This problem has followed me with 3 different airplanes so I suspect that this could be the case. From past experiences, I am scared of overuse of the rudder and several experienced pilots have stated that they never use rudder on takeoff. I am considering minimizing the amount of rudder control from specification of 20mm down to perhaps 10mm until I get comfortable with its use. Also, is it possible to strengthen the springs in the transmitter gimbals to help prevent inadvertent application of aileron or rudder?I have practiced on a simulator and it seems okay for a slight application of rudder upon takeoff. I suspect the answer here is practice - practice but would like to hear it. </span></span></div>
