LegoŽ Skidsteer loader I got the basic design for this model off the internet several years ago, and don't know who originally designed it, but it's been one of my favorite Technic models ever since. I designed the control pictured myself to drive it. It uses four pneumatic and three electrical circuits driving 4 pneumatic cylinders and three 9V motors (two motors in the skidsteer and one motor in the control itself running an air compressor). That's more controls that this particular model uses, as it only needs two pneumatic circuits (one to raise and lower the arm and one to tilt the bucket), but I use this same control for other Technics such as cranes and excavators. This little guy is VERY strong and tough. fettsplace@yahoo.com http://www.fettsplace.net Update: I found out where I got the original design... JENNIFER CLARK!
