I admit, the slipperential has been "coming" for a long time. But it is coming. The project started as something that I wanted for myself - for obvious reasons I think. The initial few prototypes were larger, limited to a 50 tooth minimimum spur gear size, and used Traxxas Revo slipper pads for the "slipper". They were also difficult to build and the plastic spur gear would melt in high slip conditions.

I wanted a smaller unit(current unit uses a 46t spur gear), a steel spur and I wanted my own slipper pads. We designed new pads, which also required a new spur gear design. We also had to get a die made to cut the new pads, as well as a die to cut the custom gaskets. Also, consider the time and cost involved in designing, testing, etc.

We have redesigned or tweaked ever single element of the design to allow optimum performance and ease of use (adjusted springs used to relieve pressure during assembly - new pads and spur gear reduce space, weight and allow smaller spur - added a teflon wear bushing and hard anodize on diff cup to allow more longevity in high slip conditions, etc...).
When we started development on this last year, it was a cool concept. Now it is smaller, lighter, more adjustable, easier to use, and less expensive product that is adaptable to many more applications than the original. I believe this product will be the ideal drive system for the high powered, larger scale electric vehicle that will be the "future' of RC. I wanted to get it right before releasing it. Hence the Patent.

The Patent process is also long and expensive and requires fairly current drawings, so as the design got tweaked, so did the patent application.

When you actually get one of these little beauties in your hands and build it, you will likely have a better understanding of the time involved in its development. What may sound like a simple task is not so simple to make small, durable, effective and user friendly. From material selection to manufacturing process - the whole thing is custom built - not some bolt on gadget, but an engineered design built with purpose. When you get one, it will have been worth the wait. :)
