(...) Yes, the XOR gates are not load bearing, but somewhere in the body. I tried to make the legs "just follow allong", but this did not guarantee that the legs were all weight bearing when needed, and it fell. I added a switch to each leg hooked (...) (19 years ago, 9-Aug-05, to lugnet.technic)

I've looked at the concept of multiple XOR gates being driven by a main loop and it will work, provided that you get the enabling sequence correct. The loop must not be allowed to advance till the XOR function has moved. Therefore the air supply to (...) (19 years ago, 9-Aug-05, to lugnet.technic)

Nice truck! The fact that the doors to the tractor can open is great! (If only your Liebherr LG 1550 had this op). How did you fix the trailer wheels to steer? Also, does this truck use ackerman steering? Thanks. The color scheme looks good for it (...) (19 years ago, 9-Aug-05, to lugnet.modelteam, lugnet.technic, FTX)
