Introduction: Lego Technic Remote Control Off Roader

About: Studying Electrical and Electronic Engineering
Me and my cousin have modified the blue Lego Technic off-road truck (set number 8435), with Power Functions from the Bulldozer, now it can drive anywhere, remotely controlled!

It will easily trek across grass, and up a >35 degree slope.

It servived a flip over a 1m slope, and then carried on driving, with no wires/parts coming loose.

We were surprised at how much torque the Lego gears can take, with the right support, we tried many methods to increase the torque, without losing speed and grip, but this is the best attempt.

Note: Perhaps no instructable will be posted, because this is a very complicated build, and we would have to show you how to take certain parts on/off the original model. I'm sure these many pictures will help though, and inspire people to build thier own.

Good Points:
>Good Suspension.
>Powerful Motors.
>Good steering.
>Excellent Remote Control.
>Makes a Great Off Roader.
>Good torque.
>The body can be easily removed for internal cleaning/inspection.

Bad Points:
>Only Rear Wheel Drive.
>Steering Centering Is Not Too Good

    That is soooooo cool. I wish I had one

    A V2 has been made! It has a better gearbox, much stronger steering and it still has 2 seats! It will be posted soon...

    UPDATE As of 1/12013 the offroader has a broken Diff! Back to the Lego Box!

    wow this lego technic is great you could make some adjustments but other than that it is great.

    Aw, man, this is good, but I'll go over some finer points that I included in mine (I have just seen yours, I build my motorized 4WD two years ago) : I did not remove any aesthetic portion of the car, besides the engine, winch, and little bits in the back, the frame is completely removable , without having to disconnect any wires, and I don't have any power functions sticking out past the original confines of the set, besides the IR receiver in front. It also involves minimal change to the original model, so it retains its good looks ;) I suggest you take a look, and perhaps improve on your own! http://mocpages.com/moc.php/251356 <-- here's mine.

    By the way, the link I gave you is to the first version, so not all of the features I previously noted were there :/

    It works really well!

    awesome, try and put oil filled shocks on it

    Well done. Would like to see more of the train setup--the tracks in the background are quite a tease. Maybe a Lego train?

    If you like, I have a video of this Railway, and my own!

    sure, provide the link--my son-in-law and grandkids are lego-crazy and love trains.

    The shocks came with the model it's self. I just modded the model!
