What do you think? Am I missing something?
The purpose of a trainer kite is
1. to promote muscle memory... how many beginners have you seen trying to steer a 12m kite by turning the bar as if they were riding a bike or driving a car?
The trainer kite eliminates having to pay an instructor to correct this.
2. to educate the flyer on the wind window
3. to educate the flyer to respect the power a kite can produce, most people are surprised at the pull of even a small trainer in 10 knots of wind... after flying one of these when they are first asked to fly a bigger kite they will have a bit of fear, and fear is good.
4. to eliminate the first few major mistakes they will make when they are first handed a big kite, being able to recover from a back-stall or knowing when to turn the kite away from the edge of the window to avoid it flying past you etc.
Its true, after a few times flying a trainer kite it becomes boring as you will have already picked up what you can from it, but still a good thing to have around when your friends ask "hey. let me try that"... hand them your trainer and tell them to call you when they can fly it blind folded... most never bother to learn so ... that was easy!
