I think so.

I've been waiting a long time for LEGO to make a large helicopter, and this one is fantastic. The gearbox is awesome, and it's nice to see the mLA's used for the landing gear. The new blades are really great. I was a bit bummed not to see cyclic control, but since I suspected it wouldn't have cyclic control, I'm not super disappointed. The mechanism used to control the collective is intriguing, and it looks like the shaft slides up/down. Thanks to LEGO for creating a large aviation themed set! IMHO, this helicopter is nearly a perfect set. Thanks, also, for creating another set that doesn't have motors with it. It's really nice to see a large set without an expensive motor and battery box.

This looks really good Tim! Nice job! I like how you mounted your mLA with the bevel gears to open/close the claw.

That's a lot of pins! You have nearly as many pins as my entire Technic collection.

I ran out of blue 3L pins when I was building my Super Cub. Most of the blue 3L pins had been used on some other projects, so I had to dig out my "old-school" Technic bin for some black 3L pins to use in inconspicuous places. I was running out of light bley 16t gears too.

Thanks for the great review, Blakbird! Is there much stress in the 6L links when the crawler is tipped to the side? I'm intrigued by the suspension design. Since the suspension rotates around the central pivot point, it seems like there would be some stress on the links when the crawler is tipped to one side or the other. Maybe there's enough slop in the pieces to make this effect negligible.

EDIT: Sorry, posted in the wrong thread.

That's a really nice design, and I like how you built the connecting rods. 6 cylinder radials do exist, and they were built with two rows of 3 cylinders. The back row was only a couple inches behind the front row, so the row offset wasn't as noticeable as the 14 or 18 cylinder engines. Again, nice job on those connecting rods. A 9 cylinder engine would be very nice. Here's a 16 cylinder radial engine I built: The connecting rods are 1x7 thin liftarms. It's not ideal, but It works surprisingly well.

Pretty neat looking engine. I like the crankshaft design. You're right, it looks more like a radial. I think the rotary engine you are referring to is the Wankel type rotary engine. Some early radial engines spun with the prop to keep cool. These spinning radials were also called rotary engines. They are a fascinating type of motor. The Sopwith Camel and Fokker Tri-plane were two examples of airplanes with rotary engines. Gnome built a double row 14 cylinder rotary, but I don't think it was used much.

Welcome! Nice to see another person getting into Technic! The quad is a nice set. Again, welcome to the forum!

I hope I'm not going too far off topic here, but has the EB group layout for next year been announced yet? I'd definitely like to contribute.

Here are a few pictures I took. Sorry about the poor quality....still trying to learn how to use this camera. That's all I've got. The collaborative display was awesome, and hopefully I can contribute next year.

This is an awesome display. You all did a fantastic job putting this together. I've got some event pictures I'll upload tonight or tomorrow. I took several pictures of the EB layout.

I have gone the last two years. If you are only 5 or 6 hours, it's definitely worth the drive. That's about the length of time I had to drive to get there. The people are great, and while Brickfair may not have as large of an international representation as Brickworld, there are usually people that come from the UK and Canada. I probably won't be in attendance this year, but, who knows, I may be able to pull it off.

Sounds awesome to me! I hope they include a folding disk and mower attachments. And if they make it green, I would be thrilled.

Those look like parts from the 8070 super car, so my guess is that you are building some sort of super car.

I'm shooting for an arrival Wednesday night, but more than likely, it'll be Thursday night. Brickworld is part of a 10,000 mile road-trip I'm doing, and I've got stops in VA, DC, and the NC Outer Banks (if I can swing that) on my way. I've been super busy trying to get my LEGO stuff built, as well packing camping gear for my trip. Fun times! This is my first BrickWorld event, and I'm super stoked about attending. It'll be great to meeting you all! BTW, if anybody needs a ride to/from the airport, let me know.

Very good idea, but does that 12t gear contact the differential? You always come up with some great ideas, and I'm curious to see what you are creating with this mechanism.

Welcome! You have some nice mocs there.

I think LEGO missed a great opportunity to add some color to the Technic line with the helicopter. It would have looked much better with a blue/white scheme. i'd like to see a silver Mercedes SLS AMG for the 2013 flagship. Not motorized, but with a working transmission, suspension, engine, and dampened doors. I'd also be happy with another road crane or a remote control forklift. As for new parts, I'd like to see longer pneumatics and an s motor.

Yup, that is exactly what I was thinking, although I wasn't sure what scale you were trying to build at. Sounds like a neat project.

Pedro Artunes, does the claw need to rotate freely only when it is holding the pipe? I'm not quite sure what your project is, but my assumption is that you want to use the motor to rotate the claw so it can be aligned with the pipe while you are picking it up. Once one end of the pipe is picked up, you want to then drag it around with the pipe turning freely as you make your turns. I'm not sure if I'm correct with this assumption, but if so, maybe you could use some sort of weight sensitive gearing system that engages the claw rotation motor when there is no load on the claw. When a load is placed on the claw, it would then disengage the motor.

Awesome!

If you don't have any Technic, I'd recommend buying a few sets to build up your stock. Building with Technic, especially studless, requires a bit of trial and error, and having to constantly wait on orders from Bricklink would be a pain. Bricklink is fine for random bits, or if you are building from instructions that somebody made, but, imho, having some sets on hand to build from is really the way to go. As far as pneumatics vs. LA's go, they both have their pro's and con's. LA's give you more control, but then you have to run all the drive axles and gearing. It's usually a bit easier to build remote control stuff with LA's. With Pneumatics, you lose the control, but mocs are usually a bit more authentic and easier to build. Pneumatics are a bit trickier to use with remote control mocs. Just my thoughts.

Except for the new motors, 9398 doesn't impress me that much. Assuming 9398 ends up being the same price as 8110, I'd take 8110 over 9398 any day.
