Well, this is my newest creation, an RC minifig scaled Daf truck. I had been working on it in the last few weeks. Now it's ready! It was a real challange for me to use power functions in this small scale or to make the video. Hope you like it!
About this creation
Length of the whole truck: 44 studs
Length of the trailer: 34 studs
Width: 10 studs (with mirrors)
Height: 30.5 plates
Steering: PF M-Motor
Driving: PF M-Motor
This picture shows a part of the mechanism of the steering, the cardan joints, which bring the power from the motor.
The tractor is based on my old Daf truck, but I had to make some modifications on the cabin, because the chassis is completely new.
Here you can see the interior, two seats in a six stud wide cabin. It was very important to me to make enough place for the minifigs.
The remote control. On the left side there is the ahead-aback lever. On the right there is the steering wheel. First it was only a lever too, but it was difficult to memorize, which direction is right or left, So I convered the motion into spinning.
The angle of the tractor and the trailer can’t be more than approximately 45 degrees because of the cardan joint.
Bottomview, it has a spare wheel, too.
The drive comes from the motor on the left of the picture, through the axle in the foreground to the differential. Then it becomes faster through the light brown and the black gears, then becomes slower through the worm screws. Only one wheel is drived on each side. I think diffi is necessary to avoid creaking in the bends and the convolution of the axles and there is enough place, so why not? The wheels are 7 stud wide. It increases the stability and makes the driving more reliable. The other two wheels (they are not drived) are own-built. They don’t bring weight, they are a little bit smaller, so the tires aren’t tight. If they brought some weight, they would steel it from the drived wheels. The result would be, that the truck couldn’t go. (I tried it, and I had to remake the truck endless times)
Chassis of the tractor.
Well, it’s not my best work. It has some faults. Most of these are in connection the steering. Sometimes the mechanism under the cabin gets loose, and if I keep the steering wheel out of the middle position too much time, it destroy the construction. This short video shows it.
I made the steering very slow, so it’s easy to steer exactly.
Another problem is to switch on the truck, because the axles of the steering are above the battery box, but it’s not too irritating to me.
I made an other longer video, which shows the truck in action, to make this was the other hard period of this MOC. Find enough large linoleum, put the lamps into good positions, wait for the sunshine, set up the background, make a camera tripod (from elastic bands and a small lamp, which was adjustable), etc. I’m very proud of it, hope you like, too.
You can find this truck on Lego Ideas. If you would like to buy as a Lego set and play with, please support! It only takes a few minutes! :)
I made an LDD file, but it removed 4 elements from the model and I don't know witch 4.
I have always wanted to make an RC LEGO truck, but thought that it would only work on a very large scale. I never thought to use the trailer for power, pretty awesome idea. Do you have to make a Cusso account to vote for it? I don't often buy sets (save my money for parts) but I'd buy this one! Only thing is it rather slow, although though if it went as fast as I'd want it would be imposable to control! XD Epic job!
Most láttam klikk fórumon,hogy neked ilyen is van.Jöttem is kommentálni. :)
Nem értem,hogy siklottam el fölötte idáig...
Nagyon tetszik már maga az ötlet is,de leginkább a kormányozhatóság megoldása viszi nálam a pálmát.Gyanítom azzal elmolyoltál egy darabig. :)
It is ingenious!!! In 2010 I wanted to build a rc truck in minifig scale, but I ran into the problem of steering and I procrastinated the project. Now, you have given me an idea!
I does not like so much the style of your truck, but the function is simply smart: 5/5!
Wow! That scale is incredible! I can't believe that it is even smaller than LP technic's vehicles! It doesn't seem that the steering is a big problem; you would have to steer for quite a long time for it to break.
Thanks for sharing the Lego Digital Designer (LDD) .lxf file! You could probably eliminate the "oversteering" problem by replacing the 24-tooth Technic Gear behind the truck cab with a similarly-sized 60c01 "Technic, Gear 24 Tooth Clutch": http://www.bricklink.com/catalogItem.asp?P=60c01 . The internal clutch slips and prevents the motor from overpowering the front steering.
Hi Gabor. I assume you can not upload your images? I had the same problem. You need to reduce the size of your photo. I went to the photo I want in Mocpages, saved the image to my desktop, then uploaded that image to cuusoo. Hope that helps. Let me know if not. I will follow you and support too. Good luck
Gabor, I think this is really great stuff and deserves much more good ratings. To squeeze all this PF gear into a truck and to get it going like this is amazing (since I started with some Technic stuff last year I know what I'm talking about). As far as I know only very few comparable vehicles exist. I'd wish there would be more sophisticated minifig scale vehicles like this to bring some movement in those quiet Lego towns! I am very impressed.
Wow, that's great! You've introduced so many functions into this 6-wide truck! And it really looks cool, too. The best thing for me is that all the functions are almost invisible. If there wasn't the IR receiver on the top nobody would notice the RC system. And take your time to figure out how to fix your "problem" with the steering and I bet you'll find a solution. I'd say this one is already a milestone. As far as I know you've made the first 6-wide RC model on MOCpages. That alone is a lot to be proud of! Great job! :-))

Your steering system is genius. I can't believe that a truck of this size can actually drive and steer without any sacrifice in looks. Superb work as always but this is definitely your best.
OK, OK, it's my best, but there is no perfect thing in the world :) Thanks for your comment!

Very clever, although a clutch gear might have made the steering... survivable? =) The back with all the gears looks great!
The clutch gear wouldn't be good. It is stronger, than the two round bricks, which keep the steering machine (gear rack, front wheels) on the chassis. There is only one method: I have to steer very carefully. Thanks for your comment!
Very cool truck and great video! It was a lot of fun to watch. :-) Building an RC model in system including PF is one of the hardest things to do, because one loophole in the construction is funest, like you discovered with the steering. Considering this was your first model with a serious amount of engineering involved, you did a great job! I'm sure next time will be even better. ;-)
Hi Gabor, this is an absolutely fantastic moc. I can’t believe you have crammed all those power functions and technic goodies into such a small package. This really is insanely good especially the diff and steering. The video is great – I love the scene where it is pulling your older creations hahaha. Amazing stuff.
