I really like the system. It’s just so consistent. My first race with the new RX8 is this weekend. I think the system is more durable than the MMM, but I think the CC 2200kv is a little faster. One thing that shocked me is there is no neutral motor breaking at all. When you let off the trigger the car will coast forever. I think with the added control of the RX8, my lap times will actually be faster. We will see.

Hmm, I hope I'm going to be ok running 16/46 on 6s in a Mugen MBX5t. Please note that I put the KV as 1410 because that was my best guess for the 1350s actual KV.
