It's interesting you say the R8 is illegal. I have gotten conflicting information. MES ports are not counted as ports is what I have been told by some. Several of the GT legal motors are 5+2's so are MES Ports legal or not. Last time I talked with ROAR, almost 2 years ago, I couldn't get a straight answer. It's frustrating. Example below of description of PICCO GT motor. It has MES ports just like R8.
