I Agree. This thing is some serious ownage. Perfect representation of a Hummer H1. But there are also many good Hummer H2 models out there. (Including mine :) ) I will be posting it sometime soon... But this certainly is the best Hummer H1 model out (...) (19 years ago, 15-Apr-05, to lugnet.technic)

(...) Well sort of. The application of torque is reversed - when steering a "1 motor per track" model, you only get 1 motor driving, when going straight you get 2. This is simply reversed in the adder/subtractor system. It's a small price to pay for (...) (19 years ago, 15-Apr-05, to lugnet.technic)

(...) That does sound like an advantage. However if I'm not mistaken, it also means less torque because technically only one motor is driving the wheels. The other one is just for steering. ?? Nathan (19 years ago, 14-Apr-05, to lugnet.technic)

(...) Nope - it means if you have two motors which are not perfectly matched (which they so very rarely are), you can still get a straight line. If you build a motor-per-track buggy, and drive it accross a long corridor, then without course (...) (19 years ago, 14-Apr-05, to lugnet.technic)

(...) What exactly is the advantage of using the adder-subtracter design versus the motor-for-each-track design? Let me guess; does the adder-subtractor design produce slow changes in direction while the motor-for-each-track design only makes quick (...) (19 years ago, 14-Apr-05, to lugnet.technic)

I built one of these myself - a while ago. The LDraw plans are at (URL) although I am yet to take some photos. My version could definately be made smaller. I intend to apply the principle to two modified servos in a non-Lego bot, although I will (...) (19 years ago, 14-Apr-05, to lugnet.technic)

(...) There appear to be 2 motors. Looking at this pic (URL) it appears the top motor drives one or other of the 8 tooth gears on the right (probably forward/reverse), and the bottom one drives the 8 tooth gear on the left (probably steering). The (...) (19 years ago, 13-Apr-05, to lugnet.technic)

Thanks Andrew, it looks like those in the UK have to order these through commotion - pitsco only ship some items over here, although I think it is more to with TLC rules than anything else. It is a shame you dont see these items on the shop@home (...) (19 years ago, 13-Apr-05, to lugnet.technic)

I must admit, it is not clear if the drive is actually driving the two tracks - in which case it will be two motors, or if it is simply driving the cylinders from the tracks - which wouldnt make a huge amount of sense, but is possible. A picture (...) (19 years ago, 13-Apr-05, to lugnet.technic)
