Never prepares you for the power of full sized one though only that you know where the different zones are.
You are spot on Peter. A true trainer kite is either a small real LEI kite or a "trainer" with a bar and chicken loop setup like the Hydra and Ozone Octanes. You really need to feel the power of the kite from the harness, not from your arms because for beginners kiting is done with the kite hooked into the harness anyway.
I tried a NASA Wing 3mtr kite once with a bar only and poah! The power of single skin kites was incredible and gave my arms a work out, and I do weights, weigh 80k and consider myself pretty fit, and even I struggled to hold her in under 10 knots. So I cannot imagine a smaller person or a lady being able to sustain trainer kites without a chicken loop for too long.
