I have seen a couple of people on the board that have used the new Ninja motor. I have finished putting together my Jammin XCR1FT and now all I need is my new mill. I know the P5 is the old reliable standby but there is something about the Ninja that has me hooked. Does anyone have any first hand knowledge of these mills and if so what are your thoughts when compared to a P5. The tracks I will be running on will be in the medium to large layout.
