  1. No it won't Motors forcibly slow down or speed up in response to load all the time. When cornering, the variable speed of the inner and outer wheels just varies the load on each motor. Lego motors are just cans in a plastic case, with some gears. They're not precision industrial motors with constant-speed controls. There's nothing there that's going to be significantly damaged in the short term by this setup. One motor might probably draw a few more mA than the other one, and it will run a bit warmer, so if you left the vehicle going round in circles for days, one motor might have a shorter lifespan than the other, but nothing to write home about If you really stalled one, the thermal protection would kick in. I'd love to see Philo comment on the topic, but eh. If the motors were constant-speed each with their own motor driver, then yes, this would be a valid concern, and the vehicle would try and run in a straight line, like a mechanically coupled axle with no diff. But I've run one-motor-per-wheel, quite a lot. If it was a problem, this vehicle with one L motor per-wheel wouldn't turn on a dime Especially given it has no weight over the steer axle, so the steer wheels are prone to floating. But it works fine see the video Sorry for hijacking this thread - I sometimes see a bit of angst in Eurobricks about using multiple motors, it's mostly no drama.
  2. Why?
  3. Eh so that's what 8109 was inspired by. Nice find https://brickset.com/sets/8109-1/Flatbed-Truck
  4. I know! And the red European-style cargo train was just a repeat of the one from 2003! https://brickset.com/sets/4512-1/Cargo-Train And that was a repeat of the one from 1994!! https://brickset.com/sets/4564-1/Freight-Rail-Runner Imagine! And even worse, the heavy haul overhead crane is just a repeat of this crane from 1978! https://brickset.com/sets/165-1/Cargo-Station
  5. Where would the 4 large gear racks be used on a grader? Two of them could raise and lower the circle maybe?
  6. Keep it simple eh? 1 L-Motor per wheel, one gear pair. Very strong, very robust, very easy to repair. Performance (click picture for video) Untitled Gallery of axle construction: https://www.flickr.com/photos/andythenorth/albums/72157649987860696 Easy to regear also. Version with Power Puller wheels (click picture for video)
  7. Convinced me to back it, cheers. Hope this one gets funded.
  8. Are you sure? Sound = energy. More sound = more power diverted to losses, not output at axle. Genuine question, as I don't know the answer.
  9. I'd want to see it in a 2x2 (width, height) form factor, but that makes it very hard to provide BI points for pins, eh? Length, no specific preference.
  10. This looks great. I hold out hope that TLG produces a PF 's' motor with roughly these dimensions
  11. Big is mostly a matter of money and patience. There's less creativity or skill in a big model, except to make it structurally strong enough. I've built big, but now I want to build small. I'm hoping that small RC models are more fun, more performant, and don't take 6-12 months to complete (and £££s of bricklink orders also). Too big, too much time, too little result
  12. About 30k or 40k, and the rest built up (out of sight in the attic).
  13. I liked the nod from the tiny 9390 tow truck (2012) to the 8110 unimog (2011) as well http://brickset.com/sets/9390-1/Mini-Tow-Truck
  14. Eh? It's just a neat nod from one set to the other. A hat tip. My kids love this stuff. But yeah, Lego is probably f*cked, let's all give up shall we?
  15. Are you building for realism or playability? And if playability, what kind? It's not an absolute choice of one vs. the other. But more realism in suspension often means less playability. Examples... Building an RC vehicle to drive on an entirely flat floor? Suspension is probably best left out. It's likely more fragile, won't survive crashes so well, makes the drive train more complex, and might be less performant (some types of suspension make power hop and similar issues more likely) Building a fully RC crawler? Yeah, it needs suspension. But the most realistic suspension is maybe not the most performant, or robust. Building a near-scale model of some real vehicle? Then you need the suspension the real vehicle has, or close to it. And it might be fragile, depending on how strong you can make it with Technic parts, or it makes the drive train fragile. But that's just my £0.02. The more you build, the more you form your own views on stuff. My kids re-enact the 'Highway Thru Hell' TV show all the time with the Arocs and the 8285 Wrecker. They rip the suspension off the Arocs regularly, the 8285 doesn't have any suspension, so the wheels stay on that. But the Arocs suspension is neat, the set would be much poorer without it. So eh
