bluehash 1,581 Posted December 23, 2013 Share Posted December 23, 2013 So I bought a Lionel Penn Flyer set on Craigslist last year. Yeaay! It came with an extra Fastrack track set with manual track changers - Awesome! This year while assembling it, I thought to spice it up a little. I already had a servo lying around. So: Servo+Launchpad+Energia+Mechanic's wire = Track switcher! Took me 10 minutes to put together.The Launchpad button S2 switches the track. Hehe .
