    I agree that the power source is irrelevant - you set up the experiment in such a way that apples got compared to apples. I was just curious about the power source. I made a DC motors vs servo motors video a while back and it also shows the same discrepancy between DC motors, minus the detailed analysis of freeze-frame. I also used a battery pack - it's good enough to drive home the concept.

    Very well thought out experiment. What power source did you use? I believe @Philo uses a regulated power source instead of a battery box to avoid voltage variations.

    Very nice work, Hans. You may want to check out this thread on a similar mechanism:

    You may want to consider a torsion axle suspension. They work very well, they rarely damage pieces if implemented correctly, and they are very compact.

    This is a very good looking build. Excellent job!

    Jeez, is it the same leg that you broke, or are you spreading the abuse over both limbs? I hope you heal quickly. Good progress on the model, it is starting to take shape. I forgot how rigid the base is, your pictures reminded me of it.

    Very good concept, but the mechanism has a very jerky up/down movement. It seems like the top non-rotating section has some give in the rotation, and causes slowdowns and acceleration in the up/down motion. It looks like a spring that gets loaded and released intermittently. Any way to make it more solid?

    I've been doing a lot of building in LDCad for the past few months and the part tree - particularly the Technic one - is extremely logical (with a few outliers). What's even more useful is the Favorite Parts virtual bin, where I put in my most used connectors, beams, axles and gears. The remaining parts are always in the back of my mind, but are only accessed through the official virtual bins when I need them. I am planning to eventually organize my parts the same way - stuff that gets used most often will be close, other parts will be hidden much deeper in drawers or bins. I imagine each builder will have a different Favorite Parts list. I don't use flex axles or pneumatics very much for example, but there are others who will need those parts in their Favorites list.

    @vectormatic Yup, you are right.

    It may allow a higher gearing, and as a consequence, a theoretical higher speed. If you gear the motors beyond a point where they can start rolling the car from a standstill, a one-time boost from the pullback motor could help get the car to a speed where the motors could take over.

    Thanks for the WIP pictures, they show quite well how you approach the shape of the car. I like the full-sized engine in the front, nice job eliminating space between it and the suspension.

    Very good review Sariel, thanks for the thorough examination of all the functions (as usual). I find the door mechanism fascinating. For some reason I thought we'd be getting more purple pieces, but it's a different shade. This will be known as the Rainbow Technic Era.

    No C model from me for the BWE.

    I wonder how much of the unfinished look is due to bean counters taking away parts from an already expensive set. Maybe the boom had cladding, maybe the bed had a floor, maybe there was a beam under the door when the designer came up with his model. I get the feeling that this set looked much better in the design stage than what ended up being produced. @Jim Thanks for the review, I'm very excited for the differentials thanks to your pictures (I don't have any old-style ones yet).
  15. BusterHaus
    I love the looks, the performance and the rear suspension. Very nice work.
  16. BusterHaus
    Considering that the BWE doesn't have a differential or engine parts, this C model is a very nice achievement. This set is very odd as far as C models go. I started making one, thinking it would be easy with such a large number of parts, but the variety of parts is surprisingly low. Lots of beams, lots of pins, but few connectors relative to the size of the set. It's a great parts pack, but challenging when it comes to C models.
  17. BusterHaus
    Very nice shape, and the pictures look great! Good use of the tusk/bone part.
  18. BusterHaus
    The trailer is awesome. The battery box is really well hidden, the functions work great and it's a nice mix of studded and studless.

    @cloud Here you go:

    @Zero (Zblj) used linear actuators in a very similar way, and the result was not pretty. The plastic piece on the end of the metal rod became disconnected. Ymmv.

    Going by memory here, but don't the instructions for motorized sets (like 9398) tell you not to play with it outside? Not that AFOLs are known for following instructions... The design of most official sets will give very poor outdoor performance. Pavement should be OK, but anything else is pretty much a no-go (mud, snow, sand, rocks). Official sets have no locking differentials and no enclosed gearboxes. Lego tires have horrible performance in snow and tracked vehicles don't have beams attached for better grip. Battery performance drops in cold temperatures, and melting snow can mess with the PF components. You're better off building your own vehicle if you plan to use it in any of these conditions.

    @Charbel Thanks for the behind the scenes video, it was very informative. You put a lot of effort into both videos, they look great.
  23. BusterHaus
    Very interesting build - the orientation of the linear actuators is unusual but makes sense when you realize that the battery box is in the way. Nice work!

    This set is a milestone, but not in a way that a UCS is meant to be. Instead of being a highly sought-after collector's piece, it brings to the table some new parts that, one of which advanced MOCs by a huge leap. The 3x13 curved panels and the wheel arches are a nice addition despite their color limitations, and the Porsche rims offer very good geometry because of their deep offset. However, the best part in the entire set is 26287: Without this part, new designs for sequential transmissions would not have been possible. It moved Technic sequential gearboxes from giant, complicated devices to compact, smooth units like the one in the Rugged Supercar by @Didumos69. This set have us some very good parts, even if its execution wasn't top notch.

    Nice work. Those parts are not easy to install for me, too. They're up there with part 15100: It's such a small part, but the amount of attention required in aligning it during insertion is beyond belief. Did you encounter it yet? By the way, I gave it some thought and I believe installing an overhead crane in your shed is the only sensible solution to installing the upper arm of the BWE.
