For some time now, Uri Valdé had been saying that a good pinion differential runs much faster than an adjustable bearing differential - which makes sense, bacause there is no power loss, given that the ball bearings do not glide along the plates when accelerating;  plus the traction is direct. Uri kept insisting and insisting until PN, the team that he forms a part of, finally decided to manufacture a few prototypes…. and the results we re immediately favourable.

 After almost two years, this is the end result of the original idea of making a quality differential by way of pinion and crowns in order to prevent power loss in acceleration.

In TRP we had the priviledge of testing out first hand this new concept of differential with interchangeable crown and we were quite impressed; especially because of its power output, that, coupled with good grip will turn the MiniZ into a rocket.

The launching of this differential as well as the new adjustable motor mount should any day now.  We will keep you informed.

TRP has started comercializing its new version of the GroupZ chassis for Slot cars on its Level 1. 
This new version features some considerable improvements on its chassis such as the use of noble materials ( e.g. Carbon SSG) that incorporates aluminium in its interior. It is also mechanized with numerical precision control of its motor mount and a spectacular anodized aluminium look.

We have´been informed that these photos don´t show exactly how the new version of the latest GroupZ V3 chassis will be sold on the market. However what we can do is give you a sneak preview on some of the new features that the new chassis will incorporate. Based on the information that we have received so far, the chassis will be on sale in regular stores almost immediately, and as far as we know a few optional and racing parts will be added so that your GroupZ Slot cars could be even more versatile and competitive.
