Costco Canada has a one day sale today on 42098, $129.99. Lego shop price is $229.99.

The small size and simplicity of this gearbox are great. I'm wondering if the friction wheel couldn't somehow be replaced by a flyweight mechanism like ones found on governors. I can't imagine it being as small as your current solution.

This is the correct solution. Just remember to have both switches in the middle (off) position before selecting a direction on one of them. They may bypass IR receivers, but physical switches are either on or off. Sariel's example (9 minute mark in the video you linked) relies on one of the switches being off to have power going only to 3 IR receivers.

From what I remember, my LDCad file with exhaust hoses on the Hammerhead was 1.6 Mb, while your version in MLCad was a few kilobytes. Ease of ease isn't always efficient.

What a beautiful model. I had to count the 2L beams on width of a track to finally understand the scale. By the way, nice trick with the linear actuator for the arm.

@Blakbird Welcome back. Any thoughts about using digital animations for sets that you don't have? You experimented with it a bit here:

I don't understand why Lego (or any other company) has to make a huge announcement regarding donations or commitments to any cause. Whether it's a commitment to education, material sustainability, or social justice, it comes off as an opportunistic way to advertise their brand. I don't have an issue with them supporting causes - most big companies have a section on social responsibility in their mission statement. They can spend their profits on whatever they want. But charity should not be used for self promotion.

LPub3D doesn't do any alignment, it takes the position from the CAD file (ldr, mpd, whatever). If there are errors in the digital build, they get displayed without being corrected. The bigger the model, the more chances that it will have misaligned parts - I believe this is because of rounding of angles/positions/orientations. The barely visible misalignments start adding up until they become visible.

You're comparing apples with pears. Stepper and servo motors are always more expensive than "dumb" electronic motors. There is a price to the precision and control that they offer. A better comparison would be EV3 components. The large servo motor is $29.99, so it looks like its equivalent is 33 percent more expensive.

Awesome work, the pull-back function is really well done. I'd venture to say this is one of your top C-models.

Congratulations to the winners, there were lots of great entries, so standing out among them is quite an achievement.

I looked at the instructions yesterday, but was very curious to see it move. Thanks for the video, the mechanism to move the wheel is quite clever.

That loading wheel is fascinating. I'm trying to figure out the mechanics of the wheel that make it act like a Geneva mechanism. From what I can tell the parts attached to the small turntable act as an escapement mechanism, would you happen to have a video showing that section?

I am definitely not the target audience for the UCS cars. The only box I still have is the BWE 42055, now used to store Christmas decorations. All the other ones went into a recycling bin.

This is quite fitting, seeing as Lamborghini was originally a tractor manufacturer.

That's very similar to 32107, and you are right - I'm looking for a width of at least 2 studs.

Are there any plates or wings that are 5 studs in length or width? I don't find anything in the ldraw library. Edit: found part 711, but it hasn't been made in 47 years.

You're reaching some crazy levels for shapes possible with Technic panels. A great looking replica, nice job. Do you always build 2 or 3 at a time?

36:10 30:6 6:4 13:3 16:2 22:1 This is the first time I had to use a spreadsheet to tabulate the scores.

A few suggestions to make it more steerable: Make the wheelbase longer with the current wheels Add a differential to drive the rear axle Try increasing the width between the wheels, although I'm not sure how much effect that will have. By the way a lot of the steering can be solved by proportional control using sliders in the BuWizz app on your tablet or phone. Instead of moving the slider up all the way right away, try increasing the power gradually.

I completely forgot about this helicopter C-model. Your version has much nicer skids, and I like the cabin shape that extends behind the seats. The buggy's got a great shape, although I agree completely that the selection of parts in this set makes for very limited design choices in C-models.

Thanks! I haven't seen any cars up to now using the fender panels as the grille - it's a bit surprising, but maybe I'm not looking around enough. By the way I had a couple of builds that had the bottom panel angled towards the rear of the car, but it was exceeding the length limit of the contest. Still a good look, may try it in the future. I tried both colors, and it's honestly a tossup. I ended up going with black to continue the two black lines on the hood through the rest of the car, even when the roof is down. Here's a picture with the red panels:

My favourite part of your builds is the novel use of half stud offsets, like the shock absorbers held by the engine/piston cam parts (sorry, too lazy to look up the part number). I look forward to future updates, keep up the great work.
