I have seen someone lifting the tail too quickly and not able to control it. He tipped the aeroplane on it's nose.
Also in long wet grass this could be a problem if you raised the tail too high or even used brakes to control direction too muchyou again could be in a world of hurt.
However the thrust to drag ratio of the machine is such that for some time as the aeroplane is getting into the air the ailerons cannot be at all effective and you must be in it for the ride for a period.
do you remember any of that happening?.
