Hi Chris, I will clarify this point, as a matter of interest this week I have received a Fly Audi Quattro for the Rally Proxy which has a drop arm which was really a surprise to me. And as this is in the eligible Dakar Classic list I measured the drop height (braid to front wheels) of the droparm which was in fact around 2cm and was greater than the Ninco Raid car I have based this rule on against which was 1cm drop. So I will need to revise this rule requirement anyway as it woukd not be my intention to bar any Fly cars from entering.

But to explain my thinking on this ruling a little more.
The intention is to run this category of cars on the SCX and Ninco track circuits without any of the ancillary obstacles (ie boulders, ramps etc), but that is not to prevent hosts still having inclines or hump back bridges etc. Indeed I don't want the basic track designs to be changed from the the more challenging Categories runs apart from that explained above.  In fact Wye Valley often use a Ninco Raid track as a normal Rally stage for standard Rally cars.

So the question is do" long drop arms" benefit cars run on relatively flat surface, probably not, whereas the guide with suspension definetly does in this context.
But in order to discourage long drop arms from causing a potential advantage in the "Dakar Sprint Race" I wanted to limit the scope of any drop arms being designed into scratch build cars.

So basically the rule for this Category R5 will be a maximum drop height (braids to front wheel in maximum open position) 2cm. (not 1cm)
