The Kombat Kopter is OK but the PT Gyro is a better trainer. I've only flown the Kombat Kopter one time a couple years ago for someone at Spring Hill and I remember it was heavy and slow response to the controls. I don't know much about the PA2 but if you put the FMA Co-Pilot on the PT Gyro and do a hand launch for you first flight you are almost guaranteed success.
