I thought hard about whether to upload this video or not. Because the build failed. But there were viewers who were curious, and it was a waste to film and edit the video, and I finally decided to upload it because I thought some of you might have something to gain from this video. No matter how high-rotation RC motors are, the motors are expected to be possible due to their large output, but this result came out. But I think the Ubox V2 I used this time was good enough. I'll try again soon. 이번 비디오는 업로드를 할지말지 고민이 많았습니다. 왜냐면 빌드를 실패했기 때문입니다. 하지만 궁금해했던 시청자들도 있었고 비디오를 찍고 편집한것도 아까웠고 또 이 비디오 안에서라도 얻을것이 있는분들이 있을것같아서 최종적으로 업로드 하기로 결정했습니다. 아무리 고회전 RC모터라고해도 모터가 갖은출력이 커서 가능할것으로 예상했는데 결국 이런결과가 나왔습니다. 하지만 이번에 사용한 Ubox V2는 괜찮은 ESC라고 생각됩니다. 조만간 다시 시도할것입니다.

I like that you uploaded this even though it was unsuccessful. It shows not every project will go smoothly even though you are an experienced builder. It's very honest of you to show us that something went wrong. Keep up the good work!

Looks like typical sensorless motor spin-up cog. try using HFI setting in VESC, it offers hall sensor/encoder level accuracy for motors that does not have hall sensor. If it works fine with no load, but does not spin up properly when there is load, you will need sensor/encoder/HFI.

It didn't fail because a build is really about the friends you made along the way. 👍🏽💯

Hello from Ukraine! I'm pretty sure you tried kickpush and then throttle. But if not - that has to be the problem. I had similar problem with my first hub motors. Moreover, i noticed that problem-solving is way more interesting then watching regular builds. So i really enjoyed vid. Keep it rolling!

Even though the build failed electrically it's still an awesome concept board and can easily be made to work with a different set of motors or something obviously. The whole thing is a win still due to the unique idea of using a deck under a deck for an enclosure. That's cool af. And I love how you keep updating this street build. The first one I liked, the second one I loved, and now I want to build a diy using a skateboard deck and skin it and theme it to a skateboard company I grew up skating, like black label, hook ups, toy machine, or world industries. It'd be pretty cool I think if it was all skinned and glass fritt and done right. Your build already proves that

Try to kickpush the board to a rolling speed and then start giving throttle! Sensorless motors have difficulties when starting. But if they are rolling, they should spin easily

*A true builder, who isn't afraid of unsuccessful builds* 👏🏼👏🏼 ⚡🤙🏼🤙🏼⚡ Thank you for sharing this, I still like the build, really like the design with the "dual" deck! I hope to see it again soon

I thought the number of subscribers is 33 million, you deserve it

Woaaaaa , quel monstre!!! Le style F1 est absolument superbe !!!! Moi j'ai mis un aileron de hpi baja 1/5 sur mon evolve GT carbon. Je pense que sur le tiens, le résultat serait encore mieux. 😉😉

i am surprise how well built and well looking it came out this project. You were in every detail. You need sensored brushless motors as they can offer hight torque at the lowest rpm because, due to hall sensors, they detect the exact position of the rotor knowing which pole power to start the rotation. It is not a problem of power but a problem of motor selection, in fact i believe 10kW is way too much for a skateoard. I strongly believe that with powerful sensored brushless motors this will end in a very high quality and custom electric skateboard

you just gave me a perfect way to make an enclosure. thank u very much.

You are an incredible artist. very impressed

Since those are high kV motors they will need the current limit set very high because the applied motor voltage at low speeds will be very low, so only way they are going to provide enough power is with high current. If you haven't done it already and the motors support it, definitely enable hall sensors, VESC will auto find very easily, and increase the current limit way higher, higher than you might think you need to, but be careful if you run for a while might overheat motors

It looks very nice !!

Great video hope to see that thing ripping soon

As always gorgeous bro looks amazing

An electric longskate. Nice. I came up with that spaced out design like 15 years ago for a low light board you could use for bombing. Making it an eskate out of it would be hella cool.

The build looks proper and very professional, other than the board being maybe a little too thin because you are putting the mounting on the sides and not directly under the main load how it is usually done with traditional skate boards, adding the layer below does help but I do not think it solves the problem if there even is one.

had the same issue but with sensored motors when the sensor cables weren't connected properly, maybe theres some extra setting in the vesc tool for unsensored motors. really cool board design.

awesome video my brother!

What sleeves are you using on those wheels? I tried the bound motor urethane but did not have good luck with it.

When I saw the threaded inserts going into there, with epoxy, I said "nooo! that's not going to hold your weight, those are going to come right out of there!" I was relieved to see that the trucks (are they still trucks when they're that crazy?) were going to be mounted properly to the board elsewhere.

we have to forget this boomer thing that being scared of failed projects. im glad u uploaded it! cheers dude

fighting !!!! sure you get it bro!!!!! 😊👍

Kick push to start. The good old days.

I’d love to hear more about your braking issues - they sound like they might be separate to the starting problems with the sensor less motors. I’ve only built one board and it was using the Spintend ubox, I noticed the bakes came off too early, but only at low (almost stopped) speed. I figured this might be how all boards work. But I’d love to know if it’s just a Spintend thing.

Looks like normal clogging fro. Sensorless motors. Use HFI, it's going to make some weird noice at first, "low RPM" but then it will ride normal, it's what I use. Also should consider using way smaller motor pulleys for that hight Kv. Thanks for sharing g the build process, there is no Fails, just a step towards Perfections!

how are you charging the batteries? individually by pulling them out of the enclosure or do you use a BMS to directly charge them without a balance connector to each battery

even though this wasnt succdessfull im happy you still uploaded it and everything, in my experience in working with brushless power systems is if typically if the motor has an issue it will cog but i feel like you should test each motor independently as i think the esc is the problem here

Did you try changing the motor style settings? You chose Inrunner , may have to choose alternate

What kind of range can a set of lipo batteries like that get you?? Im guessing that'd be considered a 16s1p??

아쉽네요 엄청 이쁘게 잘 만드셨는데 문제점 찾으셔서 고치실수있을거에요!

HFI + kickpush to start as a next step for sure. Stooge boards run similar motors with an 8s battery config in HFI/squarewave (I think, don’t quote me on that if I’m wrong) with boatloads of torque but need to be kickpushed to start.

Ne pas faire de tests c'est ne pas apprendre et ne pas progresser 👍 Toujours aussi cool les vidéos 👍

이런거 보면 진짜 너무 신기하네요 ㅋㅋ 실패했다쳐도 이렇게 만드는걸 보면 역시 일반인으로써는 신기 그자체

와 이런 영상을 보게 되다니 너무 좋네요 일단 저같은경우 데저트버기를 4셀 병렬로 배터리 4개를 4셀로 운행하고 있습니다 고카트프로 트레일러 연결해서 끌고있는데 약간의 경사도까지는 거의 문제없이힘있게 끌어 주더라구요 평지에서는 뭐 말할 것도 없구요 4셀이니까 7.4v인데 이정도에서도 20kg데저트버기와 20kg트레일러 80kg의 저를 쉽게 끌 수있는데 저 조합에서 움직이질 못한다는게 저로서는 그냥 이해 불가네요 .... 잘 봤습니다 ^^

It’s normal if u don’t have hall, u need to setup hfi to have smooth start

What happened with the 16s/Ubox setup when you kick-started the board?

would it be possible to make a portable setup? since there are two motors, it could be possible to make the weels fold in, kinda like a dji drone, and maybe a backback that can carry it would very extra but also very cool

8:54 Cute dog content

You may need to give the board (motors) a push to get it started (the esc is trying to determine which direction the motors are turning but can't because too much current is required (high KV motor and too large current needed).

Hi. What deck angle do you like best?

I will point out that while a motor may be rated for a certain voltage you can run it at a higher voltage with no issues (up to a certain point) This is commonly done in the ebike modding community. It will cause the motor to simply run at a higher RPM. Due to the brushless nature of the motors used you don't have to worry about higher voltages wearing your brushes down. In conclusion you should be just fine running the 13S rated motors with the Spintend VESC at the full 16S voltage. For the record I don't believe this was a failed build at all and love the concept of the double deck deisgn :)

Nice

С самого начала было понятно, что эта система будет работать только после движения. Как только разгонишься - тогда можно включать моторы. Потому-что такие моторы.

You are so cool 👍👍👍👍 always 🐶👏👏👏👏

Need higher c rating on the battery's 60c to 80c would allow for higher amp discharge. I personally am running 4x 6000mah 100c 6s Graphine, 2x series then parallel = 12s 12000mah. BTW your videos inspired me to get into esk8ing, and I built myself 2 custom boards.

This is a curious one. It's good to show lessons learnt during and after building. Kami took a look at it too right?

Best regards from Indonesia 🇮🇩🇮🇩🇮🇩

Try the castle creations 1717 motor its the same size but sensored

I didn't think you could do the lipos that way won't the 4s pack die way before the 6s paks. I'm so confused now lol

I think your stators are saturated. This happens when sensorless motors have high amps and volts at low speeds it causes cogging because it's difficult for it to track it's position. Did u try lower amps?

I know others have said this but the one board I have without sensors always needs a kick start… kind of annoying but it makes it work

Does the build work propperly if you manually push it once? Stand on the board and give it a good push, if the motor starts to kick in after that then the issue lies in how the motor is build, some electric motors can not operate without a sensor or something being triggered, not an expert on that matter

If what other people suggested doesn't work, I recommend running it at a lower series and higher parallel configuration since the motors have very high kv. Combined with high voltage from 12-16s battery, it would spin too fast for a set voltage, that's why maybe 4s or 6s is better with such high kv motors

good luck my friend. I couldn't find the engine, can you post the link?

Hook up the sensor cables..

Try increasing the amp when doing the motor calibration sensing.

🤣🤣🤣🤣🤣 don't mean to laugh but that's really funny ..I done same thing with a rc car I built a custom heavy duty body but evidently it was to heavy duty 🤣🤣

You dont want to feel the motors full performance. It would be an instant crash/backflip.

아무래도 높은kv모터[고회전]에 센서리스[출발코킹] 그리고 낮은 기어비가 문제인듯합니다 kv에 맞게 기어비를 많이 높여주셔야 할듯합니다 센서드지원을 하지 않으면 높은kv때문에 출발이 힘들것 같습니다 푸쉬오프하시면 아마 출발 가능하겠습니다^^ 잘 해결되길 빕니다~~

How wide is that deck

Looks really cool But in my experience, just too short for high speeds I built an old school Santa Cruise and got horrible wobble around 22mph no matter what I tried

Is it possessed?

👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍

This looks a lot like a square wave problem I had a long time ago in college where the peak of the wave wasn’t wide enough to allow a servo motor to actuate for long enough and it would just wiggle in place. It’s gotta be the settings.

High KV motors generally have less pole pairs/magnets and without hall sensors they have hard time accelerating from 0 For an electric skateboard you want at least 7 pole pairs.

For a moment i thought one motor was spinning one way and the other motor was spinning the other way haha

모터가 흐느끼노ㅠㅠ 실패 영상이라 하셨지만, 저는 빌드 과정에서 여러가지 배웠습니다. 결코 실패하지 않으셨음을 말씀드려요! 감사합니다^^

Get some good ol sensored brushless motors

I use the ubox on many of my builds including the 100v v2 for a 18s board. so the esc shouldn't be the issue. I'm surprised you still had a problem when switching back to normal motors. Would love to see detection run to try and diagnose. Making sure it's setup for 16s.

I think you need sensored motors and sensored esc's.

This is super dope👍👍👍👍💪💪🦾🦾😎😎

죄송 하지만 저 보드데크 구입링크좀 알려주세요..

Los errores te hicieron mas sabio 👌🤟👍🔩🔧🤟

Yes try HFI

If you tripple the Motor KV you are 3 times faster but have 3 times less torque. Unless you have like a 10:1 reduction those motors are stupid.

Batman longboard

I had to tweak inertia settings to a point that were insane to get bigger motors to run with my fat ass on them. Try upping it past 15 and see how you go then!

Try one day you can fly

Maybe if you started from a roll it would work.

High performance custom board. High end parts. Sensorless motor operation??? WHY.

Türkiye’de kimde öyle bişey yok

I would have push start it

Si

tl:dr : 320A sensorless motors powered by a 200A ESC wont work well. especially at the start where sensorless motor can draw way more current than rated to get going (really short spike) looks to me like your ESC is trying not to fry itself up ^^ sensorless motor under load will have struggle starting if they don't recieve enough current. the ESC being limited to 200A is your issue here I think. I see you're ESC telling the motors to go, the motors asking for a lot of juice to get going and the ESC saying "NOPE" can't do. 200A max boys :D In drone racing, setups this would be a dead esc (really cheap little and light esc don't have good current protection) I ussually imagine the power chain as a river : battery is the lake atop the montain, ESC is the canyon guiding the water to the valley and the motors are the farmers watering their crops. For the crops to grow the lake has to be big enough, the canyon as to let more water thru than the famers are using. Here I see a small lake and a very tight canyon... the crops are dying before spring. You know the motors can draw 320A to produce their advertised 10kW, You're ESC should be able to deliver this AT LEAST and your batteries should be rated for 320A continuous draw too otherwise you'll never get 10kW out of these motors and you'll probably burn something. Giving these motors are sensorless I would go for 500A burst rated ESC and batteries and 320-350A continuous esc and batteries but this is gonna get expensive very quick... using smaller motors is a better idea, go find some 3000 W motors at the same voltage (6000W with 2 so approx ~ 190A) But as I read here in the comments, going the sensored way might work : with the feedback from the motor the ESC can make them go as efficiently as it can (with less current depending on your settings :) ) I've also read you have breaking issues wich to me sounds like current limitation again. Good esc you have tho! didn't blew up! :D I'm used to drone and plane stuff that goes in flames way more easily XD and whan you showed the components I instantly expected to see flames ^^'... Also : I love the look of that board! really hope you can make it work :D

I think it's not working because those motors aren't sensored. Sensored motors will start from a complete stop smoothly, but motors like this need a push. Also, you might want to add more batteries because I doubt that those lipos will be able to handle the currents that you would want to use for motors that big, and if they do you definitely won't have much range

some thoughts. you may realize that All of the mass is supported at two 'points'; at an Angle; via a bunch of Rather small and long screws.!!!! it is probable that low-pole-count motors should not be used, for this application. such motors produce have a limited ability to 'start-up', when fully loaded. because the the load occurs at a 'large' radius/the tires, the actual amount of reduction-MA present at the load, is reduced; by maybe eighty percent.! googletranslate

Did you fail or learn something?

Always love to see your builds and follow you on instagram … is there a way to make a bigger battery for the boosted board!?
