I tried the rear motor setup last night. I'm impressed with the forethought that went into this. The pipe hanger mount, motor mounts, and filter support all just flip around. I didn't make any other setup changes. Just reset ride height and adjusted linkage and hit the track. It wasn't the best of tests because I was running bad tires and the track was very dusty. But, I did notice a couple things. The car was more stable overall, really everywhere but there are a couple spots on the currently layout which this breezed though easier. What really surprised me is that it didn't lose much steering.

I made the change in preparation for Psycho Nitro Blast, but may just keep it this way. I recommend giving it a try.
