Have any of you ever run a Plus 4?
Since last summer I've been running a Plus 4 off the shelf with Nitrotane and consistently get 13 to 14 indoors and 11 to 12 outdoors. The longest main I've been in with this motor is a 30 minutes so I pit at 10 and 20.
I really don't think Adam or Yannick need special motors to make that kind of run time.
