Looks great! I like hot rods, especially ones with a bit of rat rod influence. Interesting method you've used for the door hinges, and I like the wood planks in the bed! The engine looks like an SBC (small block Chevy) with siamese exhaust headers.

That's what I figured. Bummer. Good info though. I think I figured out where to add a second battery box, but I'm going to have to do some rebuilding. I'm glad I asked now instead of later. Thanks!

I would have 2 XL motors and 3 m motors running at the same time. Possibly lights as well.

Hey all, So, I'm working on a project, and I need you all's advice. I'm not sure whether I should use 1 or 2 AA battery boxes. Here are the total amount of PF components I will be using on my project: -3 IR receivers -2 XL motors -6 m motors -Control Switch -LED lights (maybe) The 2 XL motors will be doubled up on one of the IR outputs. 5 of the m motors will go to the remaining 5 IR outputs. The last m motor will be wired directly to the battery box via a switch. 3 of the m motors would not be used often...just in brief 2-3 second pulses and will have very little load on them. The 2 XL motors are drive motors and will be used often. The remaining 3 m motors will be used fairly often as well, one of which will have a fair amount of load to it. I'm extremely tight on space, and my project is getting pretty heavy the way it is. I would prefer to get by on 1 battery box, but I'm not sure it would supply enough power. Anyway, I'm kinda new to this PF stuff, and any help would really be appreciated. Thanks! Daniel

I like the chopper as well. The separate chain for the primary is a nice touch.

Wow....very cool.

Sounds great! I'll be watching this thread! I'd be curious to see how you make the flashing lights. I've been toying with the idea of making some flashing lights out of the PF LED lights, but I don't think I have the electrical know-how to do so. -Daniel

Thanks!

The excavator looks like a fantastic set! I'm curious to see how the motors are set up. It seems like all 4 motors would have to be in the upper part of the excavator (sorry, I'm not familiar with excavator terminology). If this is so, I'm curious to see how the power is transferred to the tracks. There would have to be two shafts running down the middle of the turn table, and while this could be done using clutch gears and a driving ring, it would hardly be ideal for transferring power down to a track. Maybe there is a diff carrier that is used instead, or even better, maybe LEGO has designed a new "axle inside an axle" piece (unlikely). Anyways, maybe I'm overanalyzing. Looks like a great set, and if the price is right, I may buy one. Rest of the sets are mediocre, and I will probably pass. The crane isn’t half bad, but the manual stabilizers are a bummer. Just my $.02.

^^^Good idea. Would the 8x4 sized 4760c01 battery box work as well?

Yeah, 5 studs isn't going to be tall enough for my first suggestion with the AA box. Second suggestion with the rechargeable battery should fit though. You could do a layout similar to that with an AA battery box, but if you want to add an extra M motor for any steer function, you would have to enlarge you interior to at least 18x8, or possibly 19x8. It would remain under 5 studs tall though. You would also have to find a place for the IR reciever.

If the interior is 16x8, I think you would have to buy the rechargeable battery box since it is much smaller than the AA one. Downside to the rechargeable box is that it is much more expensive, and you would have to buy the transformer as well. Some dimensions for the parts you would need: The AA battery box is 11x8x4 (including switch), OR The rechargeable battery box is 8x4x?. Each M motor is 3x6x3. The IR receiver is 4x4x?. How tall is the interior of your tank? If you have enough height, you may be able to place an AA battery box lengthwise on the left or right side. Stack the two M motors on top of each other and place them on the opposite side of the battery box. This would give you a footprint of 11x8. You would have to do some gearing to get your drive shafts in the correct location, which would be really tight in the remaining 5x8 space you have left. I think it could be done though. If you set up your motors and battery box this way, you would need at least an 8 stud height, plus a spot to mount the IR receiver. Now, you could use the smaller rechargeable battery box ($$$), and place it widthwise towards the front of your tank. Behind your battery, mount your two M motors in front of each other, with one motor pointing left and the other motor pointing right. You would have to add some gears at the end of each motor to get the driveshaft in the correct location, but this would be very simple. Your total overall footprint, including the gearing, would be 12x8; and whatever the height of the battery pack is. This leaves just enough room for your IR receiver. It really depends on how much height you have available. The AA battery box would be cheaper, but it would take more room and be a bit more complex to build. The rechargeable battery is more expensive, but would offer a more compact design (and no batteries!). If you need me to put together some examples, let me know. Just my $.02. Daniel

dluders, the clutch gears I have are exactly like yours. The clutch gears that I have with 2.5-5 Ncm stamped on them have the dark gray center. I got these from the old RCX 2.0 set. The clutch gears that have nothing stamped on them have the dark bluish gray center. I got these from the 8258 and 8297 sets. Interesting topic! I really wish I had some clutch gears with a bit more resistance. 16 tooth clutch gears would be great as well.

Looks great! Nicely done! What does the red driving ring and clutch gears on the turret do? Does it select between the weapons tilt and fire functions? Is there a motor that slides the driving ring, or is that done manually?

Interesting drive method you've used on the front axle. When I'm building 4x4 or AWD models, that's always the tricky part for me. Looks good!

Awesome! I really like the design of the boom. The yellow part of the boom is built very similar to how I'm planning to build the boom on one of my future projects. The black part of the boom is beautiful. Very nicely done.

Very Nice! I like the portal axles!

Thanks for the welcome! Milan, the MOC I'm working on is a remote control farm tractor based off the New Holland T9000. I thought about starting a build thread, but I'm constantly rebuilding sections of it, and a thread about may be too confusing....lol. I'm still trying to learn how to build with this studless technic system. Maybe once I get the bulk of the motorized systems completed, I'll post up, then continue to work on farm attachments and the body of the tractor. I'm also working on an off roader, as well as a WWII aircraft, although I'm not exactly sure which aircraft I'm going to build. I have a 16 cylinder radial engine and 3 blade variable pitch prop mostly completed, and I was trying to build a Grumman Avenger. The wing fold mechanism has me whooped, so I'm thinking about switching aircraft types and building something with a more conventional wing fold, or maybe switching gears altogether and building a twin engine bomber. I dunno. This is a long term project, and I've got to collect a bunch of 11x3 curved panels before I continue. My problem is I have too many projects for the amount of time I have. Anyways, thanks again!

Hey everybody! Just thought I'd introduce myself. My name is Daniel (or Dan), and I've been a Lego collector for about the past 20 years. I packed away my Legos while I was in school (didn't want the distraction), but now that I'm out, I've started collecting again. I'm a bit old-school, and I like the more classic themes, especially Technic, Train, and Pirates. Even though it's a newer theme, I like Star Wars stuff too. That being said, I really just focus my resources on Technic MOCs. I'm not overly fond of some of the cheesy new themes. Sorry. Anyways, there are some great builds on this forum, and I look forward to learning from everybody. I'm currently working on several Technic MOCs, so maybe I'll post pics of them once they are completed. And just a side note: I can't spell worth a hoot, so my apologies for my deficiencies in this area. I look forward to spending some time on this forum. Thanks, Daniel
