Philo's review of the new Power Function motors
Philo has a great summary/review of the new Power Function motors. You can read it here.
Among the items covered, he includes:
# Overview of Power Functions range
# Description of working
# Comparison with older 9V mini-motors
# LDraw and LeoCAD part files
They look the same as pictured on Philohome and the connectors are the same.
I just heard that LEGO is dumping the old train motor in favour of the PF elements in the next iteration - it looks like all the LEGO motor technologies are now merging into the PF technology - to save money in profuction cost etc.
