apemax Posted July 29, 2014 Share Posted July 29, 2014 Hey all. Well I finally started work on my next Technic aircraft, A B-25 Mitchell. It's going to be a similar size to my Technic Spitfire and mostly the same type of functions. The planned functions I have at the moment are: Both engines powered by a PF XL motor each. Working ailerons, elevator and rudder all controlled from the cockpit. Working Landing gear powered by a PF M motor. Working Landing flaps also powered by a PF M motor. Working turrets. I've so far built part of the left engine bay with the landing gear leg and the basic structure of the center of the main fuselage. First a couple of pictures of the engine bay: Reveal hidden contents Next up is the section of main fuselage I've built so far: Reveal hidden contents And thats everything for now. I'm not sure how long this MOC is going to take as I don't currently have all the pieces needed and affording them is going to be interesting to say the least but I will try and finish it before the end of the year hopefully. coffins, Arthuriel, Cyrem and 2 others 5 Link to comment Share on other sites More sharing options...
Cyrem Posted July 29, 2014 Share Posted July 29, 2014 Oh nice! What are the chances of this being a remote control one? (minus the flight obviously) and will it have reloading ? Link to comment Share on other sites More sharing options...
aidenpons Posted July 30, 2014 Share Posted July 30, 2014 Will it fly? I'm presuming you're making this plane? If so, WILL IT DROP BOMBS? How do you plan to make the turrets? An actual firing missile (like one of Lego's pre-made things?) or a TECHNIC contrivance that fires a Lego part? P.S. Can you put the images in spoilers? It's a bit of a pain to scroll uuuuuuup and doooooooooown all the time. Link to comment Share on other sites More sharing options...

If so I don't think actual firing/reloading turrets would be possible in this scale. Would be cool though. On 7/30/2014 at 5:16 AM, aidenpons said: Will it fly?

As I said above I don't think actual firing turrets would be possible at this scale but they will be able to rotate and point up and down like the real ones. Done.

apemax Posted August 4, 2014 Author Share Posted August 4, 2014 I've done quite a bit of work on the B-25 so I thought I'd post another update and show what I've done since the first part. First up I replaced the left and right landing gear mechanism with a bit better design that should be a bit stronger and work a bit better. Reveal hidden contents This is actually the beginning of the right engine bay. The landing gear mechanism is a bit easier to see on this side as it isn't built up as much. Reveal hidden contents The landing gear in the down position. Next I built the control stick and peddle for the ailerons, elevator and rudder. Reveal hidden contents As you can see this is more compact than the control system I built for my Spitfire. I've only added one peddle for the rudder as to try and fit two inside such a small area would be difficult so I thought I'd go for just one to make it a bit easier. I've also added the front landing gear as well. Lastly a couple of shots of the overall progress I've made.

apemax Posted August 11, 2014 Author Share Posted August 11, 2014 Just a quick update today as I haven't gotten much building done in the past week. I did a bit of work on the tail section and I think I've come up with a design that should be quite strong once it's finished. It's also now getting close to how long it's going to end up being once finished. Reveal hidden contents I have actually run out of 1x16 studded beams so I might replace some in the tail with 1x14 studded beams. And thats it for this update. Hopefully I get a bit more building done this week. The Ace Railgun and aidenpons 2 Link to comment Share on other sites More sharing options...
apemax Posted August 19, 2014 Author Share Posted August 19, 2014 I've managed to get a bit more work done on the B-25 over the past week so I thought I'd post another update on what I've done. First of I've done a bit of work on the control system so now the control stick has all it's outputs and I just need to connect them all to the control surfaces which will be done once I've actually made the control surfaces. Reveal hidden contents These two outputs are for the ailerons. The other part I worked on was the tail. I replaced some of the 1x16 studded beams with 1x14 studded beams and started on the very beginnings of the tailplane. Reveal hidden contents And finally the overall progress I've made on the fuselage. Reveal hidden contents The Ace Railgun 1 Link to comment Share on other sites More sharing options...
apemax Posted August 26, 2014 Author Share Posted August 26, 2014 More progress has been made on the B-25 in the past week so here's what I've done. This past week I tried to focus on the placement of the motors for the landing gear and the mechanism to connect them to the actual landing gear. I also added the two main beams where the wings are going attach to. Reveal hidden contents This is the motor for the landing gear on the wings. Reveal hidden contents This is the motor of the nose landing gear. And as usual a picture of the over progress, I'll probably work on the tail section a bit more and get the battery box mounted as well this next week.

apemax Posted September 15, 2014 Author Share Posted September 15, 2014 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. Reveal hidden contents I also came up with a preliminary design for the top turret.

apemax Posted September 19, 2014 Author Share Posted September 19, 2014 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. Reveal hidden contents 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. Reveal hidden contents Finally as usual a shot of the overall model.

apemax Posted October 3, 2014 Author Share Posted October 3, 2014 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. Reveal hidden contents I've also built a preliminary design for the tail gun. Reveal hidden contents 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. Reveal hidden contents Link to comment Share on other sites More sharing options...

apemax Posted October 10, 2014 Author Share Posted October 10, 2014 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.

apemax Posted October 17, 2014 Author Share Posted October 17, 2014 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 however want do you all think? Also I've been trying to find a design for a radial engine that I can put in the area inside the plates however I haven't been able to find one the fits that also will let an axle through without it spinning the actual engine as well. Anyone have any ideas on this? Reveal hidden contents Link to comment Share on other sites More sharing options...
apemax Posted October 20, 2014 Author Share Posted October 20, 2014 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?

Jimbob Posted October 20, 2014 Share Posted October 20, 2014 Looking good apemax, although I'm not too knowledgeable when it comes to aircraft so I can't comment on the accuracy of it. But looking at it on its own, I can definitely see it's an engine. Reminds me of the engine on LEGO set 5928. Link to comment Share on other sites More sharing options...

Just noticed that the B-25's engine is a 14 cylinder twin row engine so it should actually have 7 cylinders at the front and not eight like I have so I need to drop a cylinder from that design to make it accurate.

Isn't seven a bit of an awkward number to make in LEGO if they're meant to be equally spread? I can't imagine how you'd do that, unless the cylinders came off the axle instead of being attached to the plates. Link to comment Share on other sites More sharing options...

Unfortunately I can't attach them to the axle because they would just start spinning with the propeller which as you might expect wouldn't be very good.
