Real Dirt and Magnetic Particles

[faraway]

It should be ok as I do keep anything magnetic at least 2" away from the tracks. Ok, that "should" be. In fact did the CF-7 with RTR motor collected little metallic pieces under the motor and causes shorts for some weeks. The engines did find each other day another small magnetic pieces. I discovered never the way the pieces toke from milling on one side of the room into the south yard on the other side of the room.
It should work but you may get a surprise....
