castle creations v2

hey everyone
i was just wondering if i could send my v2 castle creations esc back to castle to get it replaced for a v3? it still works perfectly fine im just wondering if they will replace it for free? i will pay for postage to the castle warehouse. i just want a new one and since i have to send my faulty leopard motor back i might aswell send this back aswell. cause i will be waiting 2 weeks for the motor anyways. also im in Australia
thanks
Braden
