CRTlego, I'm not sure if you have purchased your shocks yet, but have you tried pneumatic cylinders for your suspension? I've seen a few people do this on larger mocs. We haven't had any snow in this part of NC yet. It got close to 70 today.

Pretty cool! It looks like it's a 2 stroke design. It sounds great! The chains and gears are just for aesthetics, and the axles on top of the motor may keep the valves from flying up too high. For a true 4 stroke motor, the camshafts would have a gear with twice as many teeth as the crank gear. On real cars, the camshaft(s) spin at half the speed of the crank. But to answer your question, it looks like the valves are pushed up/down by a lever that rides along the top of the crank (the axle that the pistons and connecting rods are connected to).

I guess you are referring to my post. My local TRU has all the 1H Technic sets, except for the log loader. From what I gather, the log loader isn't out until March, which is why I didn't list it as an exception. Sorry I didn't make that more clear.

To be honest, I don't remember if that was just the tires or both rims and tires. I think it was both tires and rims, since at the time, I didn't have any other rims that size. The rims are the standard size larger rims found on the Unimog and Supercar, so if you have those rims, new ones wouldn't be required. Your best bet is to probably order your tires through Paul or LEGO Direct. Yup, the turntable seems to spin fairly well. The gears mesh about as well as any other bevel gears that are 90 degrees apart. I think it's going to be a pretty handy part to have.

TechnicFreak, my local TRU had all the 1H 2012 Technic models in stock. I'm in NC. I agree. LUGBulk is starting up soon, and hopefully we can get the part numbers in time for the order. If you find out the element number, can you let me know?

Yup, I've had pretty good results ordering through LEGO Direct. I bought 4 wheels from 8297 for $25, as well as 100 black gear racks for the same price. The black racks weren't available on Bricklink in that quantity, and $25 shipped for 100 was pretty comparable to the grey racks on bricklink. I did check on power puller tires and pneumatic cylinder brackets, but neither part was available anymore.

Sorry, I don't have any instructions or guides for mine. I will be glad to help however I can though. I've played around with the idea of doing a youtube tutorial on how to build one, but I don't know if I have the time right now....plus I think I sound cheesy on video.

I like the tow truck, but only a V4 engine??? LEGO has been a few cylinders short the last few sets.

I ran across this on a Jeep forum while doing a google search for other LEGO stuff. I love the amount of detail built into it, especially all the little extras like the Hi-lift jack, gas can, boat, skis, winch, etc. Pretty snazzy I thought! Does anybody know who built this?

Yeah, I noticed that when I was looking at a box in the store. Pretty lame spot for a motor.

My local TRU had all the 1H 2012 Technic sets, but no BOGO50O sale. I went ahead and picked up the crane anyways. New turntable is nice!

Good looking tractor! Nice amounts of functions in such a small space too.

I built a 16 cylinder radial engine with variable pitch prop a few months back. 16 cylinders isn't really a realistic number of cylinders, and I would like to build a 14 cylinder version sometime. I'm not sure how I would build the crank. 7 cylinder engine would be difficult as well, but I think a 9 cylinder engine would be a bit easier. A 9 cylinder crank and connecting rods would take some thinking, but should be easier than a 7.

So, are you using the gearbox to have a 2 speed compressor, or does the gearbox select between the single pump on the right or the dual pump on the left?

I agree, my thoughts as well. I just wish LEGO would hurry up and make this part with the axle and pin holes in opposite locations. Pin holes at the ends and an axle hole in the middle. Every moc I build, I wish LEGO had such a part.

I would love to see some new power puller sized tires. If we are indeed getting a rock crawler flagship, I have my doubts that it will be RC. I think it would be something similar to 8466. You never know though....

The airplane is a bit better than I anticipated, but I'm still bummed that, besides the elevators, it doesn't have any other working flight control surfaces. The opening canopy is a nice feature, and the rack mechanism used for the swing wing is unique. I guess the price will determine whether or not I will buy this. The crane is a must buy for me. Those new triangle pieces are great! Much better fit.

Could you keep the switch within the system and move the switch position to the port without a hose connected to release the air? If you connect the pneumatic cylinder to the switch's center port and the pump to either the right or left port, you can use the remaining port to release the air from the cylinder without dumping air out of the whole system. Or, you could install a T connector between the cylinder and pump. Pump pumps air into the T, and one end of the T goes to the cylinder, the other to the switch. You would then have two vent ports on the switch. I suck at explaining stuff, so hopefully that makes sense.

I have a few that don't work very well. I bought them on bricklink. I think I bought one on ebay too. I have become very weary of buying pneumatic stuff on bricklink, ebay, or anywhere else online. IMHO, LEGO Education is the best place for pneumatics.

Very cool. That color scheme is really nice. I like all the chrome too. We don't have those kind of log trucks here in North Carolina (ours are standard semis), but if I remember correctly, those are popular in Oregon and Washington States.

I don't think Technic builders need an engineering degree. I don't have one; my degree is in Geographic Information Systems. For the time being, I'm a contract vehicle driver on a military installation. Gear ratio basics is the only thing I can think of that people need to know when designing a Technic moc. The rest just comes with experience.

Congrats Sheepo! Well deserved! About the time frame for models to be built: I have spoken in person to the guy responsible for the Technic Challenge. I too was under the impression that the moc submissions could only be built within the contest time frame, but after I asked specifically about this, he assured me that it was perfectly fine to submit models that were previously built. Any moc could be submitted, regardless of time spent building it. All that is required is the "Technic Challenge" sign in the picture. I have no problem with people submitting project that took a while to build, and If I get a chance, I'll probably submit some of my mocs as well. I agree.

Thanks for the extra pictures! I'm guessing the differential and PF switches are part of the 3 stage lights? And the pneumatic cylinder and spring are a pressure regulator? BTW, what video editing software do you use? The video is great!

Awesome! I'm going to have to get cracking on my moc then....I'll have some tough competition this time.

Great looking car! Paul is a great builder and a great guy to meet. Maybe I'll get a chance to see this at BrickMagic.
