21303 Wall-E with Power Functions RC

A mod of the 21303 Lego Ideas “Wall-E” set adding Power Functions motors and remote control.

When I saw the official Lego Ideas Wall-E set I knew I had to have one. But with 50,- € it wasn’t cheap at all, especially considering the extra 60+ € that I would need for the Power Functions elements to motorize the set.

When I decided to go for it anyway, it was almost too late for that. I was lucky to get a set without box or instructions at the original price. That was OK for me, but not my original plan ;-)).

The plan was: “No Wall-E without Radio Control!”. So I started looking for possible solutions other fans had found.

The most popular conversion is the one built by Youtube user PPung Daddy, but I wasn’t really satisfied with it. The cables of the motors were positioned too close to the ground, the battery box wasn’t really fixed and the IR receiver looked almost like a backpack.

So these were my main tasks when I tried to build my own version of an RC Wall-E.

I looked for better positions for the M Motors, but the best thing was just turning them by 90 deg to position the “cable exits” on the rear side. The motors are fixed by two Technic pins, the driving axles and 10 SNOT 1×2 Technic bricks with cross axle holes.file-d68dd6e4-684b-4e0d-92c2-e175cf0b421c-13893-00000dfc3d5d8d36

There isn’t much space inside Wall-E’s “belly” so I looked for the lowest possible position to locate the battery box. I built a new ground plate with a 4×8 cut out, so the ground plate of the box is now part of it. For this solution I had to get rid of the hinges of the front plate, but that was OK for me. Now the plate is just fixed by four SNOT studs.

The front of the box rests on two 1×2 Technic bricks with cross axle holes, which are fixed by an 8L axle running through them. To change the batteries you just remove the axle, then you can flip down the box.file-1ce1fd37-e838-409d-b23c-072820c24e7e-13893-00000dfc3f807535

You can switch the battery on and off by pressing the lime green lever. The hole in front of the neck part is big enough to do that without removing any parts. Looking inside you can even see the green LED of the battery.

The neck of the robot is fixed in a higher position, so the lower neck piece is one stud shorter to keep the original look.

With the lower position of the battery box it was possible to locate the IR receiver on top and more “integrated” into the design of the robot.file-d4c8e8d9-315c-49c4-b6e1-a6cf2e72e3a9-13893-00000dfc3e887f1b

With the rear panel fixed by one of the original 1×4 SNOT bricks and a modified plate with hinges on top Wall-E’s rear side looks almost like the original model. And I think even the motors look OK where they are.

I’m really satisfied with the result. The only thing I’d still like to improve is the fixation of the motors. Even 10 studs for each motor aren’t strong enough to keep the motors in position for a very long time. The torque is just too high for that. But that’s OK for me (for now).file-7def1f8d-a72e-4fa2-be42-88d358567d57-13893-00000dfc3c4975d9


So, this is my Lego Ideas 21303 Lego Wall-E with Power Functions motors and remote control (RC).

I hope you like it. My son does ;-))

8845 Dune Buggy Reloaded (Studless Technic)

img_0510

A new (studless) version of the classic Technic 8845 Dune Buggy from 1981.

Yes, I’m a big fan of the 8845 Dune Buggy, I still am. I’ve already had the idea for this classic model built with new Technic elements a few years ago. I started building an LDD model and then I kept “in the drawer” until it was time to build it “for real”.

I remembered my “old love” a few weeks ago when I wrote a review for the original model for The Lego Car Blog and I thought: “That’s so cool, maybe now it’s time to order some bricks for it”. But when I looked at the LDD model the first time after all that time I wasn’t a 100% satisfied with it, anymore.

So I started optimizing the design a little until I was. Then I uploaded it to Bricklink into a new Wanted List and used the new “Buy All” function for the first time. The experience was just “Wow, it has become so easy to get all bricks!”

After a few days I had all the bricks and got started immediately when the last of the three envelopes arrived. This was the result a few hours later:

The basic design is as close to the original as possible. Most “old” 8L bricks are now 7L beams, 8L bricks are 5L beams, and so on. The roll cage has the same dimensions (in the side view) as 8845 and the angles between the axles are the same, too.

The main differences are: The new one is one “stud” wider, the wheelbase is half a “stud” longer and I’ve added a second beam on each “lever” of the rear suspension to add some rigidity.

I’ve also added a HOG steering, something I had done on my old model when I was a kid (As I didn’t have an extra gear for the “right side” I used a longer axle going through the steering wheel, a second cardan joint and another axle plus a “spare tire” for the steering).

Here I used an additional gear on the front, a complete second steering column and a small black ball as “steering wheel” for the HOG steering (I tried out quite a few elements, even a spare wheel – but I think the ball looks best and it really works fine).

And it’s so much fun to play with it, especially for my 3-year-old son.

With the studless model finished I also got my smaller versions of 8845 out of the glass cabinet and reworked the roll cages with new holders and rigid tubes.
