Australian owned and operated
Made with ❤️ in Parramatta, Sydney. We are indeed a local Aussie small business. We are GST registered, so we pay our fair share of GST collected from our sales. Help support your local Aussie FPV store, forget those overseas stores like Banggood or AliExpress. Heck, who can really tolerate deliveries that takes 3 months anyway?!
Shocker!… we have running costs
Maintaining, stocking, shipping and importing FPV parts costs money and carries inherent risks. We try our very best to be competitive in pricing but we also need to pay wages, rent, taxes and pay for the bad stuff, like dead stock, shrinkages, fraud and importing challenges. However, we forget all this when we are able to help cure treat your FPV addiction 🙂
