CPS 3 is a High-Performance Budget DIY Submarine. Our audience have been asking us to design this for years.
It’s both:
- very easy to build (takes 3-4 days)
- simple design (no 3D printer required & ~2x less parts than CPS 5)
- affordable components (much cheaper than CPS 5 and alternatives)
And:
- maneuverable (good stabilization, etc.)
- easily expandable (with attachments)
- fast (over 1m/s)

When will you receive it?
We already designed and reviewed many iterations of the kits made by our supplier. Since it's our first batch, it will take our supplier weeks to ship the kits to us. Then we need some time to manually check if every kit is perfect. Then we'll ship it to you. You will receive the kit by the 6th of February, maybe earlier if we're lucky.
What's included?
This is the "full kit", so it includes every single component required to build the drone, and even a few basic tools. Full list of components is available here. Many of the tools from our initial Bill Of Materials is also no longer necessary (like the handsaw or sandpaper - because you don't need to cut the pipes). But you do need to get just a few basic tools if you don't have them already. One trip to a hardware store should suffice. We'll give you a short list of the tools required, all of them are very basic.
You will also get full access to the CPS 3 Course for no additional charge. We currently sell it separately for $139. Now you get everything in one purchase.
Why this price?
With the kits we're roughly matching the price of all of the components from our Bill Of Materials, but saving you the hassle of sourcing everything yourself. And we know how much time it normally takes. On top of that, some of the components are already prepared for assembly.
We're not compromising the quality of the components at all -> they are even better. We're saving money by using a really good Chinese supplier that sources everything locally. And I'm serious when I tell you that we tested everything extensively. Also, we will make sure every kit is perfect and ship it ourselves from Poland.
If you were to buy every component separately from our BOM, you would pay $490 for components (without shipping) + $139 for the course, which is $629 (plus shipping). And currently you can get all of that in one box for $675 (plus shipping).
Why limited pre-order?
We want to make sure we deliver. This is our first step in the direction of being a "hardware product" company (so far it was only online courses), and we need to start in a smart way, which doesn't make orders impossible to fulfill. At the same time, the pre-order will tell us how much demand there actually is for the kits, which will be very useful for planning the next available batch.
And if we don't deliver, we guarantee that you'll get your money back.
We would never take your money for unfulfilled promises, so in case (for whatever reason) we can't deliver you your kit, we're saving money to be able to give it back.
