Just purchased 2 CADA buggy motors and 1 CADA servo, I'm excited to see how they compare to real Lego electronics, and Buwizz motors.

In my opinion the buggy motors are excellent! I love them! The CaDa Servo can also just three positions: -90° - 0° - 90° and it is a little bit slower than the Servo from MK.

cheers, Friedl

Not as good as buwizz motor but enough for replace of lego buggy motor.

However, in my case, I was unlucky. I bought two old connectors and two new connectors, but one of each had an internal gear problem, so the sound was very noisy. (It seemed to be no problem with the operation itself.)

Odd... some people were saying it was proportional, but maybe only with some control sources? I'll test it with Buwizz 2, anyway.

Any updates? I've got them sitting in my cart, pondering ordering.

I suspect it'll be a while before I receive them, sorry. Still haven't received an email saying its shipped. Though, shipping to my country is usually very slow anyway.

[Aurorasaurus]

Well, I got the motors now. Sadly the servo doesnt seem proportional with buwizz 2.0, at least fully, but the replacement buggy motors seem pretty good.

Oddly, when I connect the servo on top of a lego PF extension lead connected to a buggy motor the servo behaves as though it has proportional control, so long as the buggy motor is running. I'm using brick troller 2 app. Same thing when connected on top of a cada buggy motor.

When connected under a cada buggy motor, the servo gains an extra spot at ~45°. Under a lego buggy motor it behaves fully proportionally.

When connected on top of a real Lego servo, neither work proportionally, while the Lego servo normally does work proportionally.

I also found the same results using the buwizz app.

add lots of info from new testing

That is really bizarre! I wonder how that's possible given the hardware. I'd be curious to see somebody disassemble one of those motors so we could see whether the plate contacting the brushes has 3 or 14 different sections on it, as I've observed on AliExpress and Lego servos, respectively. It's likely not worth risking a good motor just to learn that, though!

[Ryokeen]

Cada got new parts in their shop, like the 5x7 half-frames,split T-frame and the leaf spring parts.

I'm going to take it apart on the weekend, so we'll see. I think it has more than 3 places.

Cool, that'll be interesting!

I cant make heads or tails of it, as I know nothing about electronics, really. Hopefully someone who knows more can compare it to a real lego one, or at least photos of one. I dont quite want ro risk breaking my real lego one just yet.

Sorry for not embedding photos like I usually do, I'm on writing this on my phone.

Additionally, I tried the stacking some non branded fake servos on a buwizz motor plug and didnt get proportional results like I found with the cada motor.

Thanks for the images. You don't need to disassemble the expensive LEGO servo motors since others have done it before you.

Notice how the LEGO one has 14 individual segments on the outer contact ring, 3 on the inner and 9 pins, whereas CaDA servo has 2 continuous rings and only 3 pins for the position encoder. It seems it is fully proportional too, but since it uses different electronics/encoder, it will not be compatible with LEGO, hence the weird behavior you describe with different motors.

[2GodBDGlory]

That is interesting! So Lego servos have those 14 segments, no-name AliExpress ones have 3 segments, and CADA ones only have 1 continuous segment. I would agree with @R0Sch--they must be using an entirely different system to encode the position it's in. That would imply that it is continuous, but it limits the controllers that it works with. I wouldn't be surprised if this turns out to be more reliable, though! Those segmented contacts seem to have caused a lot of problems with my Lego servos, so if CADA has developed a different system, I'd be hopeful about their durability

 

[AVCampos]

If the segments are continuous (in which case, is it wrong to still call them "segments"?) and the servo is indeed capable of partial rotation, they most likely constitute a potentiometer. That has its potential problems, as any gamepad owner with stick drift (which happens with potentiometer-base analogue sticks, but not Hall effect-based ones) can tell you.

[R0Sch]

Btw, CaDA has an anniversary discount of 12% until May 26th. Min. order is 70$ though.

I'm in the mood for a new set.. Being brand agnostic i looked at both TLG and CADA. TLG have nothing that remotely interests me. The Military crane from @efferman / cada looks right up my street. A proper technic build, no faff, lots of gears etc so this is currently No.1 on my list - and congratulations to @efferman on this set.

I also want to ask the guys currently involved with cada, efferman and @eric trax, if there is anything in the pipeline they can share or hint at? 

Thanks

We don't know even when Claas Dominator will be released...

There is a NDA on everything we are working, so we can not confirm or deny the projects we are working on.

[TeamThrifty]

None the less, it still sounds intriguing...

Another mechanical set from JKBrickworks.

I like this option of being able to buy licenced tyres, be a good replacement for sets with generic tyres

Nice find. Didn't see these available during the anniversary sale...

I do not build sport cars, but still, those tires are interesting. Do those tires fit for standard lego rims? I mean the smaller ones, so for 1:10 scale models.

Are there any off-road variants? Did not find, but this also seems to be in the Replacement Parts section which is asking for login, weirdly enough..
