Back when I was instructing, my student's transition to his/her single-place gyro kept me up at night. A single-place gyro simply reacts so fast, compared to a lumbering 2-place, that it would be easy for a trainee to get behind the aircraft.
I learned the old Bensen way, by gyrogliding. I didn't keep count, but I probably put in over 50 flight hours on the glider (I even "gyro-glid" at Oshkosh '72). But I also spent at least that much time taxiing under power -- first without the rotor, then with it.
Yes, it's possible for a newbie to land in a crab and tip over. I think that the following things helped me avoid this unhappy experience, or worse:
(1) I was blessed with a runway that lined up with the local prevailing winds. IOW, I didn't have to deal much with cross-winds. It's critical to stay OUT of cross-winds as a beginner!
(2) In my taxi-with-power practice, I consciously steered with the rudder pedals (first with the nosewheel down and later with it off, in the "balanced" position). I got the feel of rolling in more pedal when increasing power -- of coordinating pedal with throttle.
(3) I did endless crow hops, and then runway flights, including pretty sassy S-turns. As I got better, these flights also included initiating a brief full-power climb before throttling back and hastily landing at the very end of the 3000-foot runway. Call this my "chicken out" practice phase.
(4) I made sure that I could handle the gyro, without wobbling, in a full-power level runway fight, where airspeed kept building as I moved the stick forward.* (At the time, porpoising at higher airspeed was quite the killer in our no-HS gyros. I was scared to death of that possibility.)
(5) My previous gyrogliding experience meant that the stick feel was entirely familiar -- basically that part was a nothing-burger.
If I were still instructing, I'd encourage transitioning students to do all these exercises, except gyrogliding. The stick feel I got from gliding can be learned in powered dual training.
