There are too many Black tumblers. So i made yellow version tumbler (In fact, i didn't have sufficient black bricks :-)) Anyway, my yellow tumbler has the steering system, the rear shock absorber and the 3 states transmission.
The 3 states transmission is made using 1st generation lego power function system, as you know, the system has a disadvantage that the power function motor runs only one speed. Because the remote controller has just on/off switch. So, the motor can not run various speed. (But, next Generation lego power function, solve the problem. LEGO made new controller can be control various speed)
I made the 3 state transmission, using a differential gear and two lego XL motors. It's a really simple and easy structure, but effective system. The transmission has 3 states. First state is 'IDLE', 2 motors run at reverse direction but wheels rocked. Second State is '1/2 Speed', 1 motor runs and the other motor stops then wheels rotate at half of maximum speed. Third State is 'Full Speed', 2 motor run at same direction the wheels run at maximum speed.
This is awesome. I've seen that someone else is working on a bigger sized one using Technic pieces for the panels, but his is unfinished. Question: How come you put the top lights in the windshields instead of on the top at the corners?
Your Tumbler looks very nice! I like the video too.
One question: how did you embed this video from youtube on your page, because I tried and kept trying. I went to other blogs to see how they did it, but it doesn't work for my creation.
I can tell, that it is about a Technic Ferrari 599 moc, and it contains some serious power functions and more modifications. Would you like to help me out with some tips about how to embed my youtube video? You can preview the video at http://www.youtube.com/watch?v=VJsDxQU2Mz4.
sweet this is deffinetly the best tumbler on moc pages
could you send instructions or detailed pictures of the stearing i am trying to build a tumbler but can never get the stearing to work email email@example.com
Mad props for rebelling and making a yellow tumbler. It's easier to see the great details when it's not in black, so that's also a plus.
The lights make it epic as well.
Overall, awesome job with this.
