@@drzflyest4 you picked the largest and heaviest thing I've built ;) I still have a few things I want to add to this, before I consider selling it - but also shipping this to the US would not be fun... Have you seen my G190, a 1:Tamiya scale 4x4x4 grader? That's laser cut and 3D-printed.

@@karlheinzwill7898 danke Kalle! Mit dem stärkeren Servo und Zahnriemenantrieb mit größeren Rädern macht er richtig Spaß! Kann verstehen, warum Du so gerne Bagger baust und fährst!

Hey, thanks for your interest! Not yet, but I am planning to. Do you have experience with building RC models from a combination of 3D printed parts and off-the-shelf components? What would you want to see in a file package?

​@@YensRyes I do I have a few I have downloaded from cults 3d

@@drzflyest4 Just saw your videos, nice D5 conversion! Just to make sure, you know my models are 1:32? I have nothing ready to put on cults, they would need some updating so that others can work with the files, but I'd be willing to do that unless it turns out to be too much work. Which model would you be interested in? Have a look at my playlist. I'm not sure I can recommend the wheeldozer, it's fun if you use it within its limits, but not straightforward. Are you on Instagram, you could send me a DM there.

@@YensR thanks yea I don't care size honestly

@@YensR what's your IG?

Danke Kalle!

Thank you! :)

Thank you! I enjoy watching the wheels go over obstacles :D

Thank you! I used a 49E, but I'm sure others would work as well.

@@YensR Thanks, mate. The control you showed is exactly what I need for a RC whinch control. I just received some TO 92 sensors, but my first trial didn't work yet...

Its a question of time... You brightend Up my day. I am sure I get to make It work after some testings and weldings...;-)

@@Panic853 TO92 just describes the form factor (called a package), what type of sensor did you buy?

@@Panic853 Hope you can get it to work!

Hi Elliot! Long time no see! Are you still in the hobby? 3d printing is amazing! If you want something that moves material you have to put some thought into it, but it's worth it.

@@YensR Hi. yes still in the hobby. I really enjoy the construction machinery, don't get to use it too much, but still do occasionally

@@elliot330 that's great to hear! I have more machines coming, I hope you'll like them!

Thank you! :) Yes, the superstructure is 3D printed and the undercarriage is currently Lego, but will eventually also be printed, including space for some weights to lower the centre of gravity.

haha, I know what you mean, I had forgotten about those, yes, same principle! I last saw one when I was an adult and yes, I played with it :D Like the ones you mention, it only had two functions (plus rotation)! I just uploaded another video of it (in wet sand), but in order to not spam everybody, I've hidden it: ua-cam.com/video/dJBxmXjVN20/v-deo.html

Thank you!

Thank you very much!

Thanks for your feedback. What should I improve?

Thank you Alex! When I paid for the materials, I was a bit worried :D But it all came out very well and makes great use of the space we weren't properly using before.

Thank you Segomatu! This grader is my original design, which means I bought individual complete components such as the motors, wheels, and batteries, but most of the rest is built using simple techniques from steel and aluminium profiles and sections. You can see more detail of the build process over on my flickr: www.flickr.com/photos/22070130@N07/sets/72157626598857828/ Hope that makes sense, let me know if you have any other questions! :)

@@YensR Really impressive, Bravo !

@@segomatu7063 Thank you very much :)

Thank you so much! I had some interest in my big grader years ago (which is a one off so not suitable), but not much at all for the small machines. Maybe i am doing something wrong. Also not sure what/how the best approach would be. I'm also on Instagram at jensr.builds if you are interested.

In my video: a servotester In an RC airplane: the transmitter has a switch and the retracts are plugged into a receiver which receives the command when the pilot flips the switch.

@@YensR thanks very much.

Thank you very much for the support! More to come, but there are so many projects, also around house and garden (which is where I tested this one!)

Agreed, the Melroe M880 in its dozer configuration was mainly designed for overburden and coal, so materials that are rather easy to push. And my machine has a similar weight to blade ratio. Compared to a tracked dozer, a wheel dozer should cover longer pushes at a higher speed, but I think adding the weight will improve the pushing performance with only a small speed sacrifice!

Da hast Du absolut recht Kalle! Es sollte halt ein besseres Spielzeug werden, aber es hat ein Teil nach dem anderen versagt... ...da hilft nur Neubau! Ich habe das Projekt in den letzten Jahren nicht komplett aus den Augen verloren und habe einige Teile für den Antriebsstrang zusammen gekauft. Es wird sicher noch etwas dauern, aber es ist nicht vergessen!

Glad you liked it :)

Hi Rauf! What do you mean? I tried to explain what it is used for in the video, but maybe I wasn't clear. The most common use is in modern tank drives, but it can be used in many other mechanisms, too.

Dankeschön :)

Exactly. As I said in the video, I wanted the self-locking of the worm drive, but worm drives are inefficient (whether they are super slow or not depends on other stuff, too), so I did mention that other options exist :) Thank you, I'll have a look!

Thank you! That's definitely my least favourite bit to do, but very satisfying when it's done!

Thank you! :) I am very happy how everything fit and it's surprisingly sturdy considering that there are so many cylindrical and spherical joints in such a small space. There are quite a few mini and micro servos available. On the grader I am using the ubiquitous MG90 servo. There are decent and affordable servos that are quite a bit smaller than the MG90, so I would say that area is actually quite ok. On the motor side of things, everything is N20, I have not found easily available, affordable motors that are smaller. There are some, but they tend to be limited in selection and often would require external gearing to make them useable, so at that point the smaller initial size would be moot.

thank you Tiago :)

Thank you Joe! Yes, still have it, I need to finish the last update, including soldering the electronics and my least-favourite task ever, cable routing and plug crimping! But the last two years kind of threw a spanner into the whole plan...

Thank you so much Scott, that is a great motivation for me. I am planning to do a few more short(er) videos explaining a variety of things, hopefully helping other people with their projects!

Thank you Ron, yes, I still own it, albeit somewhat in pieces. Need to get some time to solder my mouldboard electronic level control (and possible improve the code when its done) and then hand-configure several meters of servo wires and plugs to fit everything. Hate that sort of work. In the meantime, I have finished a smaller 1:32 grader but I definitely plan to get back to the big one!

Thanks man :) No stress! I've heard of shortages, but have to say that is a crazy increase! The new breed of OpenTX with Lua is very configurable, I don't think I have even scratched the surface. There is quite a bit of convenience in these radios, but also a lot of stuff I don't need, so I'm always willing to explore more bespoke options! SBUS seems like it could be huge but I haven't really explored it yet, so will watch closely what you are cooking ;)

You are totally right, still learning this, thank you :)

All good. I’ve been operating graders for a while now. I know a few little tricks

@@kingjonun9999 haha, I can imagine! I hope to be back soon, practising some more.

Thanks for your interest, Jodi! This isn't for sale, but I am planning to work on a grader that is more accessible.

@@YensR thank you but let me know when you want to sale a grader

@@jodiprosser9481 Will do Jodi :)

Cheers! This one is a one-off I built, but I am working on something more easily made. If you are interested, follow the channel, I promise there won't be any spam!

No, I haven't. I found that decent multi-turn pots cost a quite a bit money (I mean, not in the grabnd scheme of things, but...) and are rather bulky. The cheap ones as for trimmer pots are only rated for a few hundred cycles and that's not enough for a function that you regularly use. Instead I have used sail winch servos. These have integrated multi-turn pots for whatever number of turns they do.

@@YensR Some metal geared servos have a threaded hole that goes all the way through where you screw the control arm onto the servo. I replace the screw with threaded rod and relocate the PCB. Then a single small hole in the bottom of the servo case to allow the rod to pass through.... Makes a great actuator. I like to mount the potentiometer to whatever i am moving, like a swing wing B-1, so I get the throw feedback to set the limits for the wing sweep.

@@christopherleveck6835 Yes, I have used that method for quite a while on my grader mouldboard angle of attack. I upgraded it, because M3 only has 0.5mm Pitch and so you get very low speeds. It is a very convenient way of doing things, though, I agree. you can simply replace the servo potentiometer with another potentiometer of roughly the same Ohm rating. You can use rotary or linear potentiometers. You can even use the same pot and just extend the cables. Depending on how you build it, you might have to swap the outer wires of the pot around. Otherwise, it's a fairly straightforward modification.

@@christopherleveck6835 You can see my solution of an external pot, a gear motor and a servo electronic PCB here: ua-cam.com/video/JJj0foy1LH8/v-deo.html

@@YensR o

haha, not wrong!

You can use a faster gear motor, but you'll lose some force. You need to find the right trade-off for your application.

No worries - believe it or not, this is the same grader. Well. Except almost every part was replaced and updated. So this grader does no longer exist as seen in this video.

@@YensR ok thank you and God bless have a good day

Thank you, I will do my best, once this 'rona thing is gone and I can get into the workshop again!

Thank you very much :) It's been a wild ride :D

Not a bother, thank you for your continued interest! At this moment, I am sorry to say but the grader is not for sale. It's my personal development bed so to say. Additionally, due to covid19 restrictions I have not been able to work on completing the final upgrade to this machine and sadly my work on future machines has also been impacted. If you are subscribed to my channel, you will see any update first.

@@YensR ok thank you and have a blessed day

Thank you for your interest! This one needs a lot of manual work, so it would be very expensive. I am thinking about designing one optimised for laser-cutting - would you be interested in a smaller, simpler 4x4 motor grader?

@@YensR how much are you talking about

Ok I will be interested in the smaller one how much do you think it would cost

​@@caterpillarman5136 I'll be upfront with you: I don't know yet where this might go or how expensive it would be. But please read on. I would love to see more people using R/C motor graders, but this is just my hobby, so every hour I spend on making someone else's model kit/set, I can't spend on my own next model. The thing is, if I am making something for myself, it doesn't matter if I am using some obscure electric motor that you can only find at full moon when the crow creaks - because I only need that one. But it doesn't stop there. If I design something that needs rework (filing, drilling, tapping, undersized slots,...) or regular maintenance, some people will get frustrated. My plan is to have a simple but fully functional 4x4 grader that can be operated with a single 6.5-channel radio. The buyer would get a set of laser-cut parts and some special components (certain bolts, bearings, brackets,...). They would then have to assemble and paint and install components themselves that they would order from ebay or hobby stores. I'd have video/pdf building instructions available, but it would still require some experience from the buyer. The reason for that is that if I were to build a read-to-run grader it would take many hours and the shipping box would get very large and heavy. I have a plan for such a grader half-finished, but the second half is the one that hurts, so to say, tweaking it to a product that works for a customer. I would hope the parts kit would be less than 1500 USD with another 500 to 1000USD of parts/motors/electronics to be bought by the customer. Can I ask you what your background is, are you an operator of a full-size machine or an R/C hobbyist or maybe you have a different route into this hobby, would love to hear from you and what you would need/want from such a kit.

@@YensR ok thank you

Thank you Stan!
