Fixing your Lego R2-D2's angle for Star Wars 10225- Ultimate Collector's Series (UCS) model

Before I built L3-G0 I built the 10225 Lego UCS R2-D2 ("Ultimate Collector's Series", I guess they haven't thought of L3-G0, is he ultimater?")  Even before I joined the R2-D2 Builders Club, I realized that my new "ultimate" R2 didn't stand right in 3-legged mode.  It drove me nuts, so I fixed it.  Here's what I mean:

R2-D2 is supposed to have an angle between the legs and vertical of about 18 degrees for a total of 36 degrees.  However Lego's instructions for the UCS R2-D2 don't provide the right angle.  I didn't know the exact amount when I build the 10225 Lego kit, but I could tell that it looked wrong. He looks like he's about to fall on his face. 

I drew a red line sort of along the middle of the bad angle Lego kit and a green line in L3-G0's centerline.  As you can see they're pretty far off.  Notice that the back legs aren't too bad, it's just the angle of the body.

To fix it, all we have to do is make the middle leg a little longer.  To do that I moved the stop up one stud to the top of the leg support - and all of the teeth too.

Unfortunately, that means that it hits the stop plate in the center support.  That's the 4x4 plate with a 2x2 hole in the middle.  When it hits the plate, the foot won't retract all the way.

 

The fix is to remove the offending plate, which apparently isn't really needed, so you can use the cool hollow 4x4 plate somewhere else.  Here's a picture showing the removed plate circled and the stop in the space the plate had occupied.

Here's the result of our repaired droid.  A nicely inclined astromech at the same angle of the full size one.

Anyway, I hope this post helps save the world from Lego R2-D2s that look like they're about to fall on their faces!

 

I'll leave you with an annotated copy of on of the R2-D2 Builders Club diagrams showing the correct dimensions of an Astromech Unit.  I've added the 36 & 18 degree angles in blue triangles.

Now I know I'm truly way too much of an R2 geek!

 

 



First row of dome panels

Day "10", some of the first layer of dome panels. 

The dome is roughly 12-sided, but the 1st layer of dome panels has extra segments between each of the 12 sides (so it's an irregular 24-sided curvy thing).  At the top we eventually end up with 6 sides, but everything's based on the original 12 sides.

Somehow I'm missing the big round piece that I'd intended for the back, I'm sure it's around somewhere.  Otherwise the trickiest parts were the "logic displays".  I did the front ones, but the longer one is just a hole at the moment.

This section gave me a chance to attach two of the Holoprojectors!  The first parts built are finally attached.

Building Session Three

Well, something about having to work, so I didn't get daily updates.  Instead the bits are interrupted and built over a few days.

We still don't have all of the parts, so there's a few holes to fill in the results, but there's a good start on the skirt (under the body), the very top of the dome (I thought I had all the parts, but it's missing a little gray ring), and the legs.

Worked on the skirt first (daughter realized it's his butt, what do you expect from a teenager?)  Unfortunately we're missing a bunch of the "wing" pieces to round out the edges :(

It's also a bit "wobbly" because the hinges let it bend, but that'll get fixed later.  Even so, I think it's looking pretty good.  (Photos are with the skirt upside down).



I thought I had all of the parts for the tippy top of the dome (above the pie plates), so I figured I'd whip that out in about 10 seconds.  Unfortunately I'm still waiting for a little ring on the very top.  (Hopefully tomorrow).  I was able to use the flying saucer or whatever they're called parts for this part of the dome.  The angles and sizes matched surprisingly well for that.

More successfully I worked on the legs.  Again, some parts are missing, but I got further, including some complicated stuff.  Obviously they're incomplete, but I'm reasonably happy with the detail.

 

One thing I realized looking at a photo of a real R2 is that my legs seem a bit tall.  I was expecting them to attach to the plate on top of the ankle, but the distance between the notch and the bottom seems longer than on the real photo.

 

Coincidentally, the R2 builders group had a thread today that mentioned "standard" and "extended" legs.  I wonder if I followed plans for "extended"?  Clearly there's some measuring in my future to make sure I get them the right height.

 

Top is missing some of the slopes to make the recess rounded (it's a pretty complex curve), but here's the top so far.  Hopefully the slopes come today:

Time Lapse of Phase 3 Building:

L3-G0, the full size Lego R2-D2.

We've made a few Lego models, such as the Lego Disney Wonder cruise ship and a Lego Space Needle, and it's about time to do something new, but all of our ideas were pretty lame.  So in the back of our minds there was some thinking about "what could we build next?" 

Then we went to Emerald City Comicon and saw some of the wonderful Astromechs there.  Of course I wanted to build one, but quickly realized it'd be a ton of effort, cost a lot, and I wasn't terribly familiar with the materials.

It should've been obvious, but "gee, I wanna build a droid" sat in one part of my brain while "I wonder what I'll build next in Lego" sat in another part.  Eventually we came to the obvious conclusion:  "I'll build an L3-G0".  Don't know why it took so long.

Normally I grab a bunch of bricks and start building, then get more bricks, but for various reasons I started toying around with some of the sections in Lego Digital Designer to see if some of my ideas were practical.  Of course, once I started, I forgot to stop.

Now we have a 15,000 piece model pretty much figured out, and all we need are about 12K more bricks!  (Well, and some sort of frame, and some motors, and some electronics).  We're hoping that at least part of L3-G0 will be done for BrickCon in October.  Feel free to send us your spare bricks ;-)

There are some parts that will undoubtedly need changed from the LDD model, and he's going to need an internal frame of aluminum or wood or something, but it should be do-able.

A couple more screenshots of the drawing:

The model is based on plans from the R2-D2 Builder's Club (Astromech.net)  Of course brick isn't as finely detailed as manufactured parts, but he should be "pretty close" to spec.  He'll probably be about 100 pounds.  Eventually we'd like more functionality, but for a start we're looking at getting him to move and beep in time for Emerald City Comicon (ECCC) 2014.  We'd love to take him other places too, anyone know how to get him to Celebration in one piece?

We'll post more as the project goes.

Bricks acquired so far:  15900/16000.
