Thanks man, we enjoy this work!
Explanation of pricing background. Hydroflight is a super small industry, yearly total sales of units, globally, across all manufacturers is under 1,000 units. So every product has to be developed, tooled and produced to function within that reality. Remote controls for the jet ski unts are a fraction of that number. Items like the remote and the carbon fiber boards for example, are all built by hand in low number series.
Two additional factors on the pricing, the market has established a price with two competitors and there is no room for a race to the bottom which would kill future development and risk cutting corners. Secondly is the wholesale, retail margin required. There is always a difference between what you can build your self and the component + time cost and the added structure of supporting dealers around the world with a reasonable (and expected) sales margin.
All of that being said, we love open development and for the industrial design part we are sharing these designs with no restrictions hoping that people can adapt or be inspired by the images.
