Lego Power Functions - Trying to stay sane! December 15, 2013 7:12 AMSubscribe
Has anyone found a reliable source for Lego Technic Power Functions builds?
My son is really into legos and power functions this year. We've bought a bunch of the motors and receivers. We'd like to get him the Technic Excavator and motorize it like this. There are various build videos on youtube but none provide much detail. An engineer I am not! I need step-by-step instructions!
