Yes, that makes perfect sense... for a 17.5 class. The D3.5 only had issues (supposedly) with the 17.5 specifically, and only the 17.5. The 21.5, 13.5, 10.5, and everything on down, did not. Not allowing ANY of the 3.5 series motors to run kind of promotes the idea that they ALL have some sort of advantage.. which they do not, and makes it tougher for people to find the right motor to use.

But I digress... I don't really care about that race specifically as I am not attending, I was just making sure that the motor is typically allowed "in general", as there may be other races that I DO make, and that is the only motor I can run.
