What counts as a 250 size quad?

So I'm finding some 250 size frames are measured diagonally from motor to motor and others are simply measuring from motor to motor.

Any one who does any racing with a group how do you categorize quads for racing?

Always measured diagonal Motor to Motor across the center of the frame.

Currently there is no standard for Race classes. Each local group has its own criteria so contact your local racing group for rules and classes.
There is an FPV RCG forum that has a FPV Racing sub-forum that has discussions on rules and classes. Good reading.
