RE: PT 40 take-off roll
I must say that during my training, I learned to minimize the nose-wheel/rudder input unless absolutely needed. My take-off's were pretty much straight. Later on, when I moved to tail draggers, all that changed because as soon as that tail came off the ground, which was pretty quick, it was all rudder control. But, we all learn differently.
I often go from tail dragger to trike then back to tail dragger.. as batteries charge. I don't notice the changes... maybe because it becomes muscle memory. But, one thing is that my planes are usually well powered so the time on the ground is minimal.
