This time I'm using a SK3-236Kv. But I should suggest to go for the NTM-270Kv or SK3-280Kv. I just used the 236Kv because hobbyking has sended me the wrong motor for my previous esk8.Link to the remote http://www.ebay.com/itm/262779892776
were did you get the ''double'' trucks from?
Hi man do you have fb it's much easier to talk or something else?I get a pretty good range around 14km with 40km topspeed. If you gear for a lower topspeed (30kmh) you will get around 20km it's just a choise if you wanne get faster is lower range ;)For the motor I should suggest another one with a lower kv like the SK3 280Kv or the NTM 270Kv, these are better in terms of torque and power.https://hobbyking.com/en_us/turnigy-aerodrive-sk3-5055-280kv-brushless-outrunner-motor.html?___store=en_ushttps://hobbyking.com/en_us/ntm-prop-drive-50-60-270kv-2400w-1.html
Thanks man!I've sold this esk8 and I currently making a new one so instructable coming after a month I guess.There are a few things which I have changed for my new build.First of all the ESC, I have bought a 120A car ESC which is so much smoother in acceleration and wont struggle when braking. it has a program card and has much more options then the 120A boat ESC.The second thing I changed is the charger, I went for a BMS for my 6S2P lipo pack (the same pack with the same cells as I used in this build). This BMS is capable of charging the pack with a current of max 12A so that's fast enough.And the last thing is the remote, I found a very nice compact one on ebay for like 20€ and it's so much better than the big G2TB controller I had before.
Hi,Don't remove the black circlips but you need to make sure that the circlips can rotate free when the motor turns.If you make a picture of the motor srewed on your motormount, I can tell you if it's right ;)
You can directly solder them after you bought them ;)
Nowp the balance charger will do this ;)
Hi man and Thanks!The range I could get was like 15km.My friend also wanted to make a esk8 so that's why I have everything double ;)
But now I have sold mine and I'm making a new one with a slightly better ESC and faster charging
Hi, you have the esc programcard? just pull the triger in the opposite direction while riding forward and the board will brake.Do you have set the braking ''%'' ? maybe it's on 25% and it is just so weak that you can barely feel it, so you can try putting it on 50%
Carbon Bluetooth Speaker Build
That's really perfect!
I don't know another place to buy but I should use this one: https://hobbyking.com/en_us/turnigy-aerodrive-sk3-5055-280kv-brushless-outrunner-motor.htmlHigher torque and topspeed with the same setup will be like 38kmh.
Yep that's no problem, but think about the max speed which will be like 45kmh, but maybe you want a high topspeed ;)
Ja er zijn nog enkele die ongeveer dezelfde specs en prijs hebben en die zelfs beter zijn voeg ma anders toe op facebook -> Bart Roosen
Er zijn wel een paar dingen die ik zou veranderen maar dan kan ik u misschien beter bereiken via facebook?dan kan ik mijn tips die ik heb wel meedelen met u
I use a 12V 5A power supply but you just need power supply of 50W or more and a voltage between 12-16V i guess, but it's in the discription of the lipo charger ;)
No problem ;) and yep, that's correct
Thanks man!Well I have a picture wich will make clear how to connect the balance cables to a 5S pack, so it will be in the same way as a 6S pack ;)For the links, you need to dissable adblock and then open them, wait 5 seconds and 'skip ad' right above in the corner.
Yep I need to connect both to charge it
Thanks!Yes I only used the 320kV motor ;)The other 236kV motor was delivered wrong but is also a very good motor.
Yes you can do that, but you can also change the transmission or use a lower kv motor (my type has 3 versions 236kv, 275kv and 320kv) so the topspeed will be lower and the motor will have more torque so will consume less power ;)
Thanks man!I will take a look on it!
Yep underneed the rubber is the balance port of the battery pack, so it is a little bit protected for water.
Hi,I have made a kind of extended cable for the charger so I can plug it more easy into the board.
Hi,Hill climbing is no problem but of course it depends on the steepness of the hill you want to ride.Do you have something easier to conversate like facebook or google hangouts, So I can give you the tips I learned and explain you some small things I should change?
Hi,I would really like to help you with your project so if you have any questions just ask ;)1. The boat ESC has forward, reverse and braking function which is standard enabled but you can change it with the programming card.2. Well the Kv rating is depending on the speed you want to reach.I will give 2 examples by calculating:- a 320kV motor with 30/15 pulley will give you a speed of 46km/h in theorie- a 236Kv motor with 30/20 pulley will give you also like 46km/h in theorie.They will have the same torque if the speed of the board is the same because you gonna change the transmission.It's true that a lower Kv motor has a higher torque but these motors should be used in airplanes with no transmission.The only option to get more torque is to change the transmission to a lower speed of th...see more »Hi,I would really like to help you with your project so if you have any questions just ask ;)1.

And yep but I have used 6S for the first reason because it's much cheaper, 6S ESC are very cheap like the 120A boat esc and I haven't had problems, the motor is running fine and don't gets really hot. Right now I use like 75% of the motor capacity (1800W and the max of the motor is 2300W) so if you use 10S and calculate 10*3,7*80A will be like 3000W but the motor max will still be 2300W so I guess like 75% I'm using now.4. The battery pack under my board hasn't a BMS but the ESC will stop when a cell of the battery is below 3,2V. The cut off voltage can also be changed with the program card.I'm charging the batteries with a 6S balance charger but you can also use a 6S BMS board and mount it under the board which is more easy to charge it.
Thanks man yeah it's so fun to ride!And I'm not going to make a video how I made it because thid instructable already explaines everything?If you have some questions just ask me and I will explain it ?
The controller is like a rc-car controller so you can also brake with the controller.You can adjust the brake power with the programming card, the brake power is now on 25% so if that's not enough you can easy program it to like 50% or 75% ;)
Nope just the XT60 connectors to turn it on
Hi,I spent like 300€ (320$) for the parts I needed to make my longboard electric.
No, the longboard is not included so 400€ if you want the total costs
The exact weight is 6,3kg.Well if you buy the 250W charger it will take only 1 hour to charge.With the 50W charger which I have now it takes 5hours so that's my next upgrade :)
Because you need to lean left or right on the board to steer.So the truck axle will move while steering.
In my other bluetooth speaker I have used a audio usb so it's explained there already ;)
Yep they are just rubber wrist bands ;)
1 cell is made for 5A charging constant, and I have 2 cells in parallel so that means the pack can be charged at 10A.The charger is also 10A and 250W so it will be max charging at 10A.This should not effect the batteries lifetime.
Thank you very much!Nice I'm looking to see builds from other people :)I will add a new pictures of the complete schema of the wirings to make everything clear.
Or this pack is also very good but it's ticker and you can't disassemble it:https://hobbyking.com/en_us/turnigy-5000mah-6s-20c...It's a 6S 5Ah pack so you need 2 of these to get 10Ah
Hi,I should recommand this battery if the single cells are not available:https://hobbyking.com/en_us/multistar-high-capacit...Multistar does not glue their batteries so you can easily disassemble the battery to have the single cells (10Ah) seperately so you can.Here's a link how it looks like when you open the pack:http://www.electric-skateboard.builders/t/how-i-ma...
With the remote controller, it works the same as the one of an rc-car
Yes, the esc is made to be cooled by water but you don't need to do that.The esc max amps are like 100A at startup and like 60A when I'm cruisingAnd the esc isn't getting very hot
If you really want hub motors, I can recommand these:- Dual Hub Motor (130kV 6S)http://diyelectricskateboard.com/diy-electric-skateboard-kits-parts/electric-skateboard-hub-motor-dual/- Single Hub Motor (130kV 6S)http://diyelectricskateboard.com/diy-electric-skateboard-kits-parts/electric-skateboard-hub-motor-single/It's a good brand and you can buy new wheels for the hub motors wheels:http://diyelectricskateboard.com/diy-electric-skateboard-kits-parts/hub-motor-replacement-wheel/The 83mm wheels will go 40km/hThe 90mm wheels will go 45km/hIf you use a single hub I should use the 83mm wheels (it has more torque with 83mm then 90mm)When you want Dual hubs you can choose 83mm or 90mm, will both work fine ;)
You need to use flux and then it will solder very good
Thank you man!
Do you mean how it works? because that's very easy but I will add some pictures if that's necessary :)
Thank you so much!
