By the way, I have pointed out to ROAR that the motor approval needs to have the specs for the rotor posted with the approval. We recently had a motor come with a radically different rotor than the half dozen others at the track. It was .2 mm smaller in dia. than the average of the others. I was told by a ROAR rep that since it was out of spec to the approved rotor that it wouldn't be legal. I asked him what was the approved rotor since it wasn't listed. He noted that the information wasn't posted and said he would bring it up to the committee. We do know that D4's can only have the purple and turquoise as that is the two motors approved. Tuning rotors aren't listed for those motors at this time.
