I don't know how strong the gear train is, but every time I see a set with the fake motor I think, hey? The motor is geared directly to the diff, could I take out the fake motor and put a pf xl motor instead? The hand of god typically is even more convenient to put a m motor and a worm gear, too. I tried on the off roader, but the gear train was quite weak. That will be one of my first mods when I get my hands on this set. :)
