MOC: Technic B-25 Mitchell

Hello everyone,

Well it's been over a year since I last posted here however I've finally finished my B-25 I've been working on for just over a year and a half. It's had several major rebuilds of certain sections since the WIP topic I posted but It's finally at a point where I can call it finished and start on something else.
Some basic info first, It's wingspan is roughly 3ft (around 92cm), Fuselage length is about 2ft 6in (around 76cm), It has a XL motor for each engine. so that makes two, It has two M motors powering the landing gear and it also has working flaps, ailerons, rudders and elevators (All controlled though the control column and gear wheel in the cockpit.). The top turret can rotate 360 degrees as well. As you may notice in the pictures below I ended up not being able to fit the battery box into the actual model as there just wasn't enough room for it, As it turned out though it came in handy as one of the annoying flaws with this model is it won't actually sit on it's landing gear, It just falls backwards so the battery box was just the right hight to prop it up. I spent a long time thinking about the problem but couldn't come up with a solution for this particular model so it's just something I'll have to keep in mind for future aircraft with tricycle landing gear. Anyway, on with the pictures.

Thanks for reading and hopefully the next LEGO MOC will come a little quicker than this one did. ;)

MOC: Nebulon-B Frigate in LDD WIP part 11

Just a quick update today as I haven't managed to work on it much this week. I've just been adding a few more details here and there around the model.

Been working on the Nebulon B Frigate over the weekend so here what I've got done.

I've added some more colour to parts of it and I've also added a few small details here and there as well. What do you think?

MOC: Nebulon-B Frigate in LDD WIP part 9

Just a quick update today. I've been working on the colours a bit since the last update as well as a few smaller details here and there. I've changed the plates where the red line is to be a bit smoother and I've also added a bit of colour to certain places as well.

MOC: Technic B-25 Mitchell WIP Part 13

As I haven't posted pictures of the actual model for a while I thought I'd do just that and show you what it's looking like now. I've built a possible design for the tail turrets canopy but I'm not 100% sure on how it looks at the moment but it's a start at least.

And a picture of the overall progress I've made with it.

MOC: Technic B-25 Mitchell WIP Part 12

I've been working on the engine design a bit more over the past few days and something I noticed was that the design I made before had 8 cylinders however the actual radial engine in the B-25 is a 14 cylinder twin row radial engine so there should actually be 7 cylinders at the front. I had to think about it for a while but I've come up with a possible design for 7 cylinders. I'm thinking this is going to be more or less the final design for the engines as I've got the look somewhere around where I want it and it lets the axle spin freely. What do you all think?

MOC: Nebulon-B Frigate in LDD WIP part 8

I've done a bit more work on my Nebulon B Frigate over the past week and what I've been focusing on this time is the colours. I've done a test render in pov-ray to see what the colours are going to look like when I do the final renders as the colours are a bit different in LDD to LDView/Pov-ray as you can see in these two pictures. What do you think?

MOC: Technic B-25 Mitchell WIP Part 11

Another quick update today on the engine design of my B-25 project. I managed to come up with a possible design for the radial engines in the B-25 in LDD. What do you all think?

MOC: Technic B-25 Mitchell WIP Part 10

A bit of a different update today as I haven't got much progress done on the actual model however I have been trying to come up with a good design for the front of the engines. I've made this in LDD as I don't really have the pieces to make it on the actual model and I'm just trying to come up with ideas at the moment.

I think it looks better than it looks now but I kinda want a design for a radial engine to go in the front however I haven't though of one yet. But anyway that's all for this time.

MOC: Nebulon-B Frigate in LDD WIP part 7

Another update on my Nebulon B Frigate today. I've done quite a bit of work on the rear engine section to make the shape of it look a bit closer to the actual thing although I have messed up the internal structure a bit but oh well, I'l fix that at some point.

Still a bit more internal work to be done as well as external details but thats all for now. Till next time.

MOC: Technic B-25 Mitchell WIP Part 9

Just a very quick update today as I haven't gotten that much done over the past week.

The main thing that I focused on this time was the front section. I've built the preliminary design of the cockpit canopy and nose canopy and although there is still a few bits to be added I think it make the nose section look much better.

And that's everything, Yep told you it would be quick. Anyway, Till next time.

MOC: Nebulon-B Frigate in LDD WIP part 6

Been working on the Nebulon-B Frigate over the week end so I thought I'd post a update.

First thing I did was work on the plates on the front section quite a bit so they look a bit more like the actual thing. I've also increased the strength of the center section by adding a second row of beams under the original row. These two main beams almost run straight through the entire length of the model so it should be much stronger now.

And thats it. Till the next update.

MOC: Technic B-25 Mitchell WIP Part 8

I've got some more work done on my B-25 over the past week so I thought I'd post an update to tell you all what I've done.

I've improved the tail section a bit by adding beams going straight up the under side of the fuselage as well as building a bit more of the tail it's self.

I've also built a preliminary design for the tail gun.

Another thing I did was put in the battery box and IR receiver where they will go. I'm not 100% happy about how far the battery box sticks out the top but I'm not sure how to solve that one yet.

And thats it for this update, Till next time.

MOC: Nebulon-B Frigate in LDD WIP part 5

I've gotten some more progress done on the Nebulon B Frigate over the past few days so here's what I've got done.

Biggest thing that's changed since the last update is I've completely rebuilt the front section so it's now wider and a bit better overall shape now. I've also added plates to the sides of the center spar to help with the look of it.

Still a bit more work to do on the front sections plates but that's it for this update. Till next time.

MOC: Technic B-25 Mitchell WIP Part 7

Another quick update today as I've made a bit more progress on the B-25 so here's what's been done.

The main thing I've been focusing on over the past few days is the tail section which as you can see is starting to look a bit more like the real thing. I still have a way to go yet but I've finally got the control surfaces on the tail working well so the only control surface left to get working is the ailerons which I can only to do once I've actually made the wings.

Something I forgot to put in the last update was that I had actually built the propellers. They are a similar design to the propeller on my Spitfire but smaller as this model is in a smaller scale.

Finally as usual a shot of the overall model.

And thats it. Till next time.

MOC: Technic B-25 Mitchell WIP Part 6

Finally got some more work done on my B-25 over the weekend so here's what I've done. I've added the other side of the nose section as well as completely replaced the control mechanism for the elevator control to using beams as the original way of doing that (using axles) wasn't going to work. I've also run the rudder control mechanism to the tail as well although I haven't added the actual rudders in yet.

I also came up with a preliminary design for the top turret.

And thats everything. Till next time.

MOC: Nebulon-B Frigate in LDD WIP part 4

I've been working on my Nebulon B Frigate over the past few days so here's an update on what I've done. I've added a bit more detail to the rear section as well as finished off the detail on the bottom of the front section. I've also been thinking about the colours so I still need to sort them out and there might also be a few minor tweaks here and there as well. I also need to sort out the internal structure as it's a bit of a mess at the moment.

Also I should hopefully have a update to my B-25 soon as I've finally got a few more of the pieces I needed to carry on building it.

MOC: Nebulon-B Frigate in LDD WIP part 3

I've got some more progress done over the past few days so here is an update on what I've done. I've done the other side of the front section as well as started work on the very bottom part of the from section, I've also added more detail to the rear section. I'll probably do a bit more work on the rear section as well as the bottom of the front section next.

MOC: Nebulon-B Frigate in LDD WIP part 2

I've gotten a bit more done over the past few days so I thought I'd post an update on what I've done. I've replaced the bricks on the rear section with slope bricks and done a bit more work on the front section as well. I still need to do the same for the other side and work on the rear section a bit more.

Still a lot more work to do but it's getting there I think.

MOC: Nebulon-B Frigate in LDD WIP part 1

So I finally got around to working on the Nebulon-B Frigate again that I started building in MLCad quite a while ago however I've decided to build it in LDD (Lego Digital Designer) instead. This way
it will be a bit easier for me to make it in LDD. I imported the old model so all that progress is still there so I'll use that as a base to carry on with it. I've done a bit of work on it already but there's still quite a bit left to do. here's my progress so far.

I'll hopefully be posting updates to this any week that I don't have an update for my B-25 project so I should get a update out on either build at least once a week. Anyway till next time.
