0.4 First Stunt Kites
The easiest to learn beginners kite is a diamond (Powell/ trlby/
dynakite, etc) One of the biggest advantages to a single diamond
is the ease with which you can re-launch after a crash. Kiting
can become very frustrating when you have to keep walking 150' to
set up a kite. These kites also verge on indestructible.
3/4 deltas (Team/ Spin-Off/ Extreme/ El Nino/ Stinger 750/
Wizard, etc) might be good 2nd kites, but their increased speed,
both forward and turning, make them harder to learn on (though I
certainly know people who have learned on them). Their lower
pricing (usually between $75 and $130) makes them attractive to
beginners who aren't willing to dump a lot of money into a new
hobby, but this doesn't necessarily mean they're good kites for
Full-sized deltas (Spin-Off/ Hawaiian Team/ Super Sky Dart/
Slingshot/ LiteFlite/ Phantom/ Big Brother, etc) are a fairly
good place to start, though the price can be inhibiting to a
beginner. However, there are plenty of good full-sized kites
that are good for learning on; slower air speeds, a nice tendency
to never stall, and so on.
With all of these kites, as Marty Sasaki says, it's probably best
to stay away from graphite-framed kites at first, as they are
easier to break.
