A
heat race/main event or creation of a racing class can only exist at a BADRC
event if there are at least three of the r/c vehicles present that are
considered to meet the requirements of that type of class as outlined in the
BADRC class rules. Classes may be
grouped together with other types of similar scale
r/c vehicles in the event that there are not
a minimum of the three of the same class of r/c vehicles .
This is acceptable if and only if all racers of all heats of the said
“grouped” vehicles are in agreement. If
an agreement cannot be reached then a refund of the non-grouped racers entry fee
will be returned. Every possible
combination for grouping will be considered by the BADRC race director as long
as the level of competition for the group is fair and not advantageous to one or
more of the types of vehicles in the grouped class.
An example is there are
two electric powered 1/10 scale trucks and all 10 1/10 scale gas truck racers
are in agreement that they can be entered into their BADRC race event.

measure the engine above the surface. No flat chassis (1/8 buggy style).
