CIM motors

In the rule it states that we can use up to a maximum of 2 extra 2 1/2" CIM including the ones that come with the kit. Now, my question is, are we allowed to use the 3" CIM plus the four 2 1/2" CIM motors to have a total of 5 CIM’s (one 3" and four 2 1/2"). Any help would be appreciated, thanks in advance!

You may use up to 4 2.5" CIM motors.
You cannot use the 3" CIM motors.
