Posted September 13, 201410 yr Hi Lego Technic enthusiasts I'm new at this Forum and wanted to show you my Lego Technic Tumbler. Tell me if I did something wrong with the post/sections/whatever! :P I've seen lots of Tumblers on Youtube, but I'm quite shure that no one built an AWD-version. So this is what came out after three months of studying how this could be possible. Due to school I couldn't spend much time with building, I think in total I had about 30 hours. -Key idea: Using the old flex system for the steering -Weight: 1400 grams (without battery box) -Length: 42 cm -Width: 24 cm -Suspension -AWD -Shooting cannons at the sides -rockets that you can swing out -LEDs -RC -No slipping gears, perhaps I should have used two XL-motors Just watch the film on youtube: Thanks for reading! :) Edited January 31, 201510 yr by Jim Embedded video
September 13, 201410 yr That is truly ingenious. It never even occurred to me to try to build an AWD Tumbler.

September 13, 201410 yr Cool idea for the steering. I was thinking of using chain drive for each front wheel but this also works. Nice job.

September 13, 201410 yr Very well done, especially the rear end. The Sunday driving speed made me laugh.

September 13, 201410 yr Very specific Tumbler-interpretation, but I like it! Proportions are quite off, but it does not matter.

Yes I realized it when the Lego 76023 Tumbler came out.. there you can see some huge differences..:/ On 9/13/2014 at 2:59 PM, timslegos said: The steering mechanism was quite interesting, well done! tim On 9/13/2014 at 2:27 PM, Rishab N said: Great work.

September 13, 201410 yr Welcome to Eurobricks swisstechnic This is a brilliant and ingenious build. Well done

Lol thank you! :) I would say they could have built in at least a working steering..:/ On 9/13/2014 at 8:06 PM, grum64 said: Welcome to Eurobricks swisstechnic This is a brilliant and ingenious build.

January 31, 201510 yr Very nice model ! could u post a few more detailed photos of your tumbler ! TANK YOU !
January 31, 201510 yr Very cool! The functionality and details are very impressive. I agree with rollermonkey. The pwnage is strong with this one.
January 31, 201510 yr Wow, that's a really interesting solution - nicely done! It's too bad the flex system didn't last - it was a real innovation. Indeed, PWND is right! Did you experiment with trying to get it a little bit faster? Not easy with such a sophisticated drive train, I realize...
February 1, 201510 yr Welcome to the club and great first post. If the tumbler really had to function the way its supposed to in real life... I am sure it would have to have an AWD mode.

Hey aeh504 Thank you for the comment :) Yeah it's a shame that they don't have the flex system anymore.. for example the new cargo plane would be even more impressive with some flex cables.. I didn't really experiment with the drivetrain - I just didn't want any crackling gears. I could try to build in 2 XL-motors connencted with a another differential for more power and change the gear ratio. (The Tumbler is still in existence) Currently I'm building a loom for a school project so I don't have too much time for that Have a nice evening! :) On 1/31/2015 at 8:15 PM, m0dulo said: Very cool!

Hey abhilego Of course I can! :) As it's already evening here, the light was very bad in the house. I hope they are good enough for "what you need" - or I will make some tomorrow. https://onedrive.live.com/redir?resid=70C2CE3E3CD6C319!8051&authkey=!AMTdGFNkzMOutks&ithint=folder%2cjpg Have a nice evening
