Hi, I have the SkyMaxx Pro V2 Order #17850, and I want to buy the upgrade, how I get it? I went to the site http://www.x-aviation.com/catalog/and dont found nothing, also I logged in to my account and dont found nothing that said v3. Could you tell us were we can download it. And if is 50% off for v2 Users, how apply the discount. Thank you.
