    With buwizz (or brickcontroller2) you can program it to add 2 motors right away in the throttle, then a third, then the fourth at or near full gas. In this way you can ease the acceleration a little, and save CV joints. I don't know how it is with s brick, but I guess similar. My only problem after that is driving ability and how bits keep flying off the front end.

    Yes he is.

    The clone servos are all junk. They operate digitally, but even if you're using Lego digital controls they're no good. If they get an instruction to turn left, they have to turn a full 90° then return to the centre. This is horrible for drivability of any larger or faster model, although you can get away with it on small stuff especially if they only have a limited steering angle anyway. They're often stronger and faster than Lego servos which isn't a benefit, as they'll rip apart a lot of steering racks especially if it is built to block the steering physically before 90°

    I'm pretty sure it's something else. The servo worked for an hour or so of play, then hit and won't work right again. The circuit which senses the position is kinda janky, relying on multiple sliding connectors each of which runs into a PCB with resistors and whatever else. I think one of those tracks has failed or a component wasn't right from the beginning.
  5. amorti
    I tried that. It's probably a fault in the circuit board itself, because it was only a few hours of play old and the tracks were clean, nothing damaged.

    I found the steering worked really well on 42099 (rocky). I let the bc2 app centre the servo and it worked just fine, right away. Trust gxt590 and Samsung A5(2017). Some people had an issue with lag on Android, there are posts on it higher up.

    Seems like Lego owes you two replacements? Otherwise get three shipped to your neighbor or your mom. Easy.

    If it's RC cars you want then the ideal would be the crawler as it would have the V2 infrared receiver.
  9. amorti
    I'd suggest the recent set 42099 as a good starter. You can then build the Rocky b-model and there are a few other worthy MOCs on rebrickable too. But it uses control+ rather than power functions which limits the reusability of the RC parts. Any power functions kits would of course have to be bought secondhand now.

    Good to hear I'm not the only one, mine exactly does this: It was bought via BrickComplete, and came brand new in the original packing. I guess it doesn't cost me anything to ask them. Thanks for the tip! It'll never come now: PF is dead. I'm really hoping the various Chinese makers issue a new version with analog steering, and including their more powerful electric motors.

    Reminds me of this guy: Can friction be increased with these ? https://www.bricklink.com/v2/catalog/catalogitem.page?P=98283&idColor=155 Or this, with grilles on it? Obviously you'd have to put something on the back to get an axle hole too. https://rebrickable.com/parts/11213/plate-round-6-x-6-with-hole/

    There does seem to be more than a few items "oh, and one more thing" added on. The whole body does look like it'd break apart very easily.

    Interesting time-spanning style with studded beams and frame, liftarms, panels, flex axle, and ribbed hose. I even see an old style bevel gear on the differential, that takes me back!

    I have one where if it gets to (approx) the 4th position out of 7 in one direction it'll shoot to the 7th, and stay there. The other side is fine. I already pulled the model apart and took the motor apart to try and fix it. Solved it for a few minutes then it started doing it again. No clue what's actually wrong with it but that's 30€ down the toilet.

    It's the best pure-ish Lego solution and it fits great in the model. But 2* buwizz costs 229€, which is a lot of money. It's especially a lot if you already have sbricks and lipos in the house.
  16. amorti
    Those cost 60e where the thing I got was 40e, and it has a phone holder built in. Admittedly the PS4 pad will hold a secondhand value, but I'm happy with my choice.
  17. amorti
    From a hardware point of view, I think it would only be possible if the discrepancy is a whole "step", which is 1/15th of 180 degrees =12 degrees of rotation (ish). I think most times, that would just skip over a tooth and put the misalignment on the opposite direction. Have you already had a play with the dead zone function? I did just connect it to my Rocky build of 42099. The Control+ servo function works really nicely. I think it's also put a little more "zip" into the whole thing :)

    Don't know - I have not tried it myself. From a youtube video I saw, you need a spare PF plug, a 2S LiPo (you can use 3S but then you need to add a DC-DC transformer as a voltage limiter?) and a steady hand. Not sure how you'd guard against excessively draining the LiPo. They don't like that. Maybe just make a special point to stop driving it when the vehicle starts running slower. IDK if there's an easy circuit or component that would do that function. That may be thinking too hard though, apparently cells are OK down to 2.5v each. I think before Greyhound got down to 5v, it wouldn't be able to move.

    Yeh, probably the battery. Looks like it is fused at 750mA, I am pretty well certain the S-brick will deliver much more, and the 4x L-motors will certainly ask for more to beat a 2kg model's inertia. As you have an S-brick, I think the answer might be to adapt a 2S lipo battery.
  20. amorti
    Assuming all wheels are turning the same direction, it's still a heavy model and maybe 1 S-brick can't manage? Or maybe the one rechargeable battery hits its limit first? I know in Icarus, Madocca uses two rechargeable batteries and two S-bricks, maybe that's why.

    I decided that connecting a PS3 pad by wire every time was dumb, and paying 60€ for a PS4 controller that might play nice, was dumb. I bought one of these, which also holds your phone for you (although you might want to limit that feature to indoors use, e.g. while you're programming the pad/app): https://www.trust.com/en/product/22258-gxt-590-bosi-bluetooth-wireless-gamepad https://www.amazon.co.uk/Trust-Gaming-22258-Bluetooth-Gamepad/dp/B079G339J9/ref=sr_1_2?dchild=1&keywords=trust+gxt+590&qid=1593426976&sr=8-2 It only claims to work with Android and Windows, so iOS users will have to look elsewhere. The app is brilliant. The pad is brilliant. I'm pretty excited to drive my models without having to look at my phone at the same time. Thank you @imurvai - what an excellent app!

    I still haven't tried my Icarus outside properly. It's such a job to take the two buwizz out of greyhound. And Icarus is so fragile that honestly I'm worried about driving it outside. But from driving inside I can say it drifts like crazy at ~8 volts, and can snap the head clean off a CV joint.

    I've just been flicking through the instructions, wishing I had all the pieces to hand. The front suspension is interesting for a few reasons: It doesn't use the usual wobbly ball joints, but similar to Bruno's P1 a frictionless pin instead. It use aerofoil wishbones at the bottom, these should help triangulate the suspension to be a bit less wobbly than usual. Because of that, it has unequal length wishbones, so like a real car, the way they're mounted should give a little negative camber through the stroke? Does it suffer any bump steer? The rear is cool too: Aerofoils triangulate everything for less wobble Did the rear suspension work out OK with the too-short driveshafts? I guess the axle sliding in the wheel hub is enough to take up the slack? I'll gather up the parts one day soon-ish. I've got a fair bit of it already.
  24. amorti
    This seems like a bad idea. I can't imagine a way to make a driveshaft using that which would run smooth. You know Lego CV joints slide on an axle, right? This gives enough extension for any reasonable suspension setup. If you need more, you need to look at why your driveshafts need that much extension (wrong geometry)

    As it's Chinese stuff, I'll ask @Jim his opinion first. Does this come under the heading of improved PF parts like buwizz, or does the fact of it shipping from China (and specifically a moc stealing company) mean it's a no-go?
