A competitor who has won the HPI Challenge European Finals in a previous year is welcomed to enter the same class again. However, it must be understood it is not possible for the same competitor to win the Main prize (the plane ticket) more than once in the same class.

It is only possible for a competitor to win 1 Ticket at each European Finals.

Drivers entering more than one class at the European Finals can only win 1 main prize (the plane ticket). If one competitor wins two classes, he/she must decide which class they would like to compete in at the world finals.

The top 2 drivers in each class automatically qualify for the European Finals.

All other places will be allotted nearer the end of the season, depending on place allocations to the UK at the HPI Challenge European finals.

No sponsored or supported “Team” drivers in the RS4 Mini Class, RS4 Sport Class and the RS4 Nitro – Stock Class.

No HPI fully factory sponsored drivers will not be allowed to compete in the HPI Challenge series.
