Hey, just got a used kite, it??s a Slingshot School C kite with 4 lines....can't find any info on this kite, somebody can help me???

Warning if it is the fuel it is not a begginers kite!

It's a Slingshot Ignition School most probably 2005. Designed for beginners but out dated safety system in comparison to late model kites. Don't risk your neck on this one. You can pick up post 2010 kites for peanuts that would be a far safer option.

you will be better off getting a $200-$300 kite from the buy sell section on this website. it will be old n clapped out, but much better for you to learn on than that. saying that. it will still be newer that 2005. get your mate to have a look before you buy.
my first kite was a fuel 13m (similar to the one pictured) and it will take you a lot longer to learn and your bound to be thrown around lots
