When I bought the 4PKSR I thought about the M12 too, but my friend said Sanwa mini servos for 12 scale might have problems using Futaba servo and Sanwa's own small servos are not good....
The only reservation of me getting M12 is that I am sure with the 4PX Sanwa would have a color screen tranny in the pipeline...given the M12 debut in 2012, might just be an update with a color screen next year
