Yeah, that was my point. It wasn't clear if he was talking about on the ground or just as the plane lifts off. The aileron is pretty much ineffective on the ground, well, for flight I mean.. it will cause the plane to tend to "roll" even on the ground with enough speed on. But as soon as those wheels leave the ground, then the ailerons are doing their thing and it comes down to control and gaining height in a straight line.
