- Part 2: • DIY Electric Longboard...
After being inspired by folks with fancy electric skateboards I decided to take a shot at building one rather than paying $1000+ on an e-board or expensive DIY e-board kit.
Top Speed fresh off the charger = 42kmh / 26.25mph.
Materials and cost in USD:
-Pulleys+belt -5mm HTD pitch, 9mm wide - $~35
---Big Pulley part #: A 6L25-030SF0908
---Small Pulley part#: A 6A25M014DF0906
---Belt Part #: A 6R25M057090
-Motor: SK3 5055-320 - $46
-Radio+receiver: Quanum 2.4Ghz 3ch Pistol Grip - $22
-Esc - HobbyKing 120A Boat ESC - $47ish
Batteries: Turnigy 5000mAh 3S 20C $22ea.
Battery box $5
-Longboard/ Skateboard - $Varies
-Misc: Wire, stainless hardware, deans connectors, solder, aluminum plate, balance leads - $~40
-Shipping: I live in Canada - All electronics came together $~30cad from HobbyKing + $40cad. ish duty fee. Pulleys/belt $~35cad shipping.
Shipping for the belt and pulleys was very high so I recommend you order a few belts and possibly different gear ratio combinations to save on extra future shipping charges.
Motor/Esc/radio came from HobbyKing.
Purchasing from hobbyking - If you stay on the same page for a few minutes it'll usually prompt you a cheaper price by a couple $$ for 2 or 3 items, start with the more expensive parts then add cheaper parts after.
Belt/Pulleys came from sdp-si - IMO they have the best selection. I couldn't find another retailer as complete as these guys. Expensive shipping though.
Nice build !
I'm building mine too, got the same quanum tx & rx. How did you plugged it ? throttle is CH1 right ?
My Motor & ESC would not start and keep beeping unless I plug the ESC signal on the CH3, and use the tiny CH3 button as the throttle lol. It's really weird it does not detect anything else than ch3, did you have this problem ?
+Tahitian Rider Ok so I figured that ch 2 is the throtlle, and that neutral point is actullay all the way to the front (not in the middle) with throttle trim turn full to the right too. Is there a way to change that on the radio ? it is weird to have to push your finger all up front against the spring to be at zero throttle lol
+Tahitian Rider I have my esc plugged into ch2 on the receiver. Dial back the throttle trim knob, it should be somewhere in the middle. All the way forward is like full throttle cruise control. Turn it on and dial it back until the wheels stop. Hope that helps. Cheers
+Eric B Thanks for your help :) I got the point of finding where the wheel stop and start using the throttle trim. But on my radio, to have the wheel at zero throttle, I have to be at one end of the thottle stick, I can't have it in the middle neutral position, I'm not sure if that is clear... reverse won't be possible for example, but maybe it is because of my ESC that needs to be programmed for that.
great build bro. greetings from Mexico.
Out for a rip are ya bud?
30 seconds in and i can already tell that you're Canadian.
Thank you so much. I couldn't find a UA-cam video that had inexpensive parts! Helps a lot!
good video Eric
i have the Enertion K1 Dual motor kit , going to build up soon
Currently riding a Evolve Bamboo At/ St board
Having the same motor driving the two rear wheels will make your rear truck drift while carving.
How long did it took you to get the tunirgy sk3? Cause I've just ordered one (they are on backorder) and apparently people has been waiting for 3 monthes and haven't received it yet
+redcshnovic Best bet would be to ask someone on their online chat. Once shipped about a week and a half.
Ive got the same remote. Which channel do you use and what is the setup process for this receiver?
Very nice and clean build man, Love it!
I was asking how the connectors call which you need from the 3 motor wires to connect it to the ecs, because the boat esc hasn't any connectors standard?
Thanks! The esc just has wires with no connections on them, those must be soldered on. The motor comes with banana jack style connectors. Hope that answers your question,
hey eric, great build. I'm currently ordering all my parts to make my own board with two 280kv sk3's. just wondering do you have the exact names or part numbers to the gears you used, since I'm using a very similar motor to you i could proberly get away with using the same gears/ belt. is there any chance you can help me out, spd/si's website is kind of confusing. thanks so much in advance
Just added to description
So you CAN use a rc airplane motor with this? rc car redio aand all?
Its really hard to listen to u as you sound like you are 100% bored...
How did you weld the bracket to the truck? Isn't the truck aluminium? Do you have a TIG or something?
oxy acetylene torch with filler rod. It held very well. I did however end up re-doing with with 1/4" aluminum plate from metalsupermarkets.com. The plate I used in the video kept bending. 1/4" plate is solid like a rock.
A great build bro! Amazing how much torque they have! I'm building one right now using a Milwaukee drill assembly, video should be our once I get it finished.
Thanks! Brushless motors and lipos are pretty great.
I can buy one for 70 dollars up to 200
Thank you bro.
Yo Eric, i got the same ESC 120 amps - did u have to adjust anything with a esc controller card ? of was it good out the box?
You know a way to program it?
Running it as-is out of the box. Working fine so far. Never figured out how to program it.
Hi! did you set your esc for break and how? tnx
What did you use for securing organizer box onto deck? I worry the plastic will crack if I use nuts and bolts.
I used 6 small screws with large-ish washers. I later added a bracket over the box because I had the same concern. Check out my pt. 2 video for more details on that.
please share the flat of the metal parts. thanks a lot! awesome project!
Nice video! Well planned!
Hi Eric! i think i ordered the same gear set, but i noticed that the smallest gear didn't fit the shaft of my motor, did you have the same issue or did i just ordered the wrong gear piece? Love your work man !
Thanks man. If it's tight check to make sure the set screw is backed off enough. If the pulley is way too small you could try to drill it out. Make sure the shaft size and bore of the pulley are the same. Sounds obvious but something might have been packaged wrong assuming you ordered the correct pulley/motor.
hows the brakes on the boat esc? does it work? is it strong?
nice video keep it up
Isn't it a problem that your esc is not being cooled by water? Doesn't it become like very very hot?
Surprisingly it doesn't get that hot at all. My guess is that a boats pulls a lot more current turning a prop in water. The motor doesn't really have to work that hard on an e-board if it's geared properly, and only really pulls a lot of current under acceleration. I've actually had it cool down from 115f to 105f while cruising at 30kmh on flat.
Can u show us all link those you bought?
Where did you buy your pulleys and belt? I can't find them.
SDP/SI
Part numbers finally added to description. Good luck, Cheers.
how long the diameter of the wheels
what type of batteries r u using
Hey Eric, Amazing video! I was wondering how you got your Transmitter to work. I have the same reciever and transmitter but when I set it up, the transmitter only moved the motor when pressing the channel 3 button. Any suggestions? Thank you!😉
Brooklyn Hanon you figured it out? mine isnt working either
I did, but honestly I have no idea how I did it I I just unplugged the reciever from my board multiple times and finally It switched to the trigger. Good luck though...
how many miles you can drive with this? (sry for bad english)
+MrNoNaMe2003 Check out my running video, link in the description. 8-10km at a good pace.
Hi, Why did you choose the batteries with low discharge ? Can you answer
Thanks
They were cheap. Also, I don't honestly think a battery with a higher c rating would do much for it anyway. Unless you want to do 100kmh I see it as a waste of beer money.
That is good opinion, but how long are using the batteries and do you use longboard every day ? Thx
Hey man! You connected 2 batteries in serie, are they 3s , so together 6s? or did you connect two 6s batteries, up to 12s?
+DJBeelen Two 3s to make one 6s
+Eric B okay thanks!
I need help to make this esc and motor stop!! Its going really fast and I don't wanna stop with my nose!
dont you Mean tail?
you should extend esc motor cables and shorten batt esc cables otherwise you may ruin esc with too long cables
I see what you're getting at, and I've never put an amp clamp on the wires to see how much current the esc actually pulls, but based on how much heat it generates I don't suspect much, so i'm not that worried.
+Eric B please have a look at this link. take care
www.rcgroups.com/forums/showthread.php?t=952523
Hi, I have the same controller, but it dosn't work. It is correctly connected to ch3 but the trigger don't work and if I push the button ch3 it works... How did you setup the controller?
+SiMyt848 Try plugging the esc into the ch2 slot on the receiver.
+Eric B Yes, it worked on the channel 2! The problem was the throttle channel... thank you!
Does it have brakes?
+Vladimir Longrod I'm also interested if this board has brakes!
+Matthew Wiese Yes, most esc's have brakes. They are pretty light though since it's a marine esc, which isn't really a bad thing at speed. They are about as efficient as foot braking. If you want strong brakes go with a bulkier car/truck esc.
ahh gotcha, thanks for the insight!
Are you having problems with belt tension?
+Adam Keely I was, It was slipping on the drive pulley so I mounted two skate board bearings together as an idler pulley to take up the slack in the belt. Put the idler road side/slack side of the belt. It helped A LOT. In my opinion this is a better idea than just going crazy tight as it also wraps the belt around more of the pulley. Just be careful not to get lube on the belt from the bearings.
Which motor would be better?
Alien 6374 Outrunner brushless motor 170KV 3200W 65,- GPB
ore
Alien 5065 FR Sensored Outrunner brushless motor 270KV 2000W 45,- GPB
Do keep the price in mind :)
the 5065
I'm assuming you're from the uk. which site are you buying your components from?
***** I bought my stuff from hobby kingbut it seems like they're out of stock right now.
Can someone please help me find some large washers like in the video? +Eric B
You'll have to look up a fastener store in your area. You won't find anything that big @ HomeDepot or Lowes. I got mine from Ottawa Fastener Supply.
Which software did you use for creating the motormount?
AutoCad
How far do you get with the 2x3s 5000mah?
It varies a lot on the terrain and how you ride. If you're nice to it and it's flat/ smooth 16+km easy. If your on the gas and it's hilly maybe 9km with a fresh charge..
Taking in consideration the research, time consumed, work involved and money spend, and aside of the fact that is a satisfaction to make something like this on your own and learn to do it or customize the skateboard to your needs, Do you think is worth it versus buying a commercially available electric longboard such as the evolve bamboo or boosted? thanks for any objective answer!
+marzbite I dont know what your time is worth but in my opinion: Boosted boards are very reliable (dont know about the others). They also cost $2000 for the top model. Very expensive for a toy, very cheep for a vehicle. I am always tinkering around and have been longboarding for about 7 years. Seeing a project come together and be successful after doing the research is a big part of the fun for me. And In a sense I probably saved an additional $50 by working on this a couple evenings by staying in haha!
Bought:
- Super easy
- Might come with a Warranty?
- Fun right away
- Generic deck (unless boosted board)
- Proprietary electronics
- Have to deal with manufacturer for diag. help.
- Some parts might be hard to get to replace
- What if the company goes bankrupt next year?
Built:
- Time consuming: Fun for some - Frustrating for others
- Your preferred deck
- If you buy known electronics your local hobby shop could help with future diag.
- Can save you $ if you already have tooling and don't use a diy kit
- Confidence in knowing where every part came from, parts easily replaced/improved
- Easy diag. - You built it - you should know the weak points.
- It's yours!
- Your wife/gf will love you for not blowing all the vacation $ on a skateboard.
+Eric B thanks man, great insight!!! love your video, thanks again!!!
Nice Job!!. what size are the green wheels.Thanks
Thanks man! 72mm
can you done à name of pulley
Can you post a link to the actual gears you used in this build? Thanks.
Part #'s are in the description
Hey sweet build but i was wondering how the boat esc is doing? Should i buy that one or a more expensive one? thanks.
Go for a VESC! I find that it's a bit more expensive but, much better for an esk8!
- Neil
Big Kids ive already got one! I finished my build like 2 months ago.
Gabriel Robinson nice! Building a board is such a rewarding experience!

What is ESC do you use?
+Alexander Bidyuk Added to description
Thank!)
Eric B can you do a video on how to solder the batteries and then connect them please cuz I'm really having trouble with mine
Can you please post exact link or exact name of the motor? >> Thumb up for that build! It looks great!
+Petr Friedrich SK3-5055-320 from Hobbyking. Just checked and don't see it listed anymore. The sk3-5055-280 would be the next closest match.
+Eric B Thank you. :)
Little late to ask but do you know if i could possibly find an idler for a 3m 15mm wide pulley manufactured? a little too much hassle to make myself.
Not sure bud. Its easier to make one than you think. Just a bolt a bearing and a couple of washers.
Oh. Okay! Thanks for the help!
Where can i buy these things like The motor etc. Link?
Hobbyking.com,
Take a look in the description
hello i have a 930 kv motor its the pyro 600 09 you think i can use for an electric longboard ? really nice video
You cannot use such a high kv rated motor it will draw too many amps and kill your Esc
Not a good choice. Way too high rpm (fast). Get something that will spin slower with more torque. Pay attention to shaft size when you get your pulleys as the vary.
Can I have the link of the radio, please?
Can't find it :c
Quanum 2.4Ghz 3ch Pistol Grip, copy/paste into hobbyking search.
+Eric B Ok Thx
Hey can you put some pics of all the motor bits how they are attached batteries etc and can you put a link to the print out as well please still it is very detailed well done I liked it as well and sub
Also can you link the product is for motor as there are a few types thanks
And where do you get the esc and batteries from can you link it and pulley belt gears from please it will help so much thank you
+_Amrit_ product id
How did you attach the case with the batteries to the board? Did you have to drill more holes in the deck?
+ColindaPieman Its screwed to the deck. Drilled holes in the box, the screws were small and did not need a pilot hole in the deck.
+Eric B You are using rubber washers with that so no water/moister leaks in.
Is the esc getting hot? (at full speed?- by climbing hills?)
+Adrien BLACHUT Its still pretty miserable out where I live so no full test yet, I took it out for a quick rip about a week ago to see how it worked and it had really good power. Accelerated hard even at speed. ESC was slightly warm to the touch after my 10min ride - which I think is pretty decent, most esc's are safe up to 185-190F. I'll give an update when the weather is nicer. Salty roads are bad for electronics.
+Eric B Thank you and many thanks in advance
can you give me the link to the ESC
www.hobbyking.com/hobbyking/store/__28224__HobbyKing_120A_Boat_ESC_4A_UBEC.html
It's sold out at the moment 😞
Link to the transmitter and receiver?
+Jackson Menke Go to Hobbyking, search product id: 9249000805-0
Nice Video 👍 does the transmitter have a break funktion?
+German FPV Thx. Yes, the transmitter does throttle and brake/reverse. It works just like any entry lvl. 3ch radio. If you want "good" brakes however I wouldn't recommend the esc in the video. Its very light, about as efficient as foot braking.
+Eric B thanks
where did you get the gears from? cause i dont plan on buying a whole assembly from enertion.
+Eriaz Iverson sdp-si, info's in the description.
+Eric B okay but which store was it from?
+Eriaz Iverson nevermind
Would a 350kv motor be able to pull a 60kg rider?
+Finlay Sambrook Smith If you're looking at the sk3 350kv motor I wouldnt recomend it. 5mm shaft will limit drive pulley choices, and it's only meant to work on 4/5 cell = 19v. 6 cell is best = 22v.
+Eric B oh ok thanks. Looks like I'll have to save to get a better motor
Why so much discussion about VESC and ESC? Does it really matter? I mean, the difference between them is so freaking big to worth the double priced VESC?
As with anything there will always be a more expensive way of doing something and someone to justify it. I personally didn't care to invest too much money into an unknown project. The way I see it a big long spec sheet won't make your board more fun to ride, so I personally don't care about all the features, and any esc that supports lipos will have a low voltage cutoff which is all you really need. Regen braking is nice but you'll get that with a car/ truck esc as well as strong brakes.
Is it possible to brake with boat esc?
Yes, it is.
So, tell me how, because I bought the same esc and motor, I change the settings to forward, reverse and brake, I increased the reverse to 75% and I could not brake even in a low inclination street!!
Boat esc's have weaker breaks most the time, because its unnecessary to have a strong one in a boat. but if the break can slow you down enough to put your foot down to break then its fine. But you can also try to make a physical break that will stop your back wheel.
hello, does the esc work good and doesnt burn up ???
Buy a vesc
It works fine, doesn't heat up to any point where i'd be worried. More on that in my other video. Any 90+ amp esc would work fine for this though.
Top speed/range???
+Jack V Range Haven't done a top speed pass or really test for range yet. I can tell you it'll do 22mph at 2/3 throttle. If I had to guess i'd say 27-29mph, but will confirm later on.
Do you need to do all that balancing thing if you only have one 5000mah battery?
+Finlay Sambrook Smith Nope. But by connecting two 5000mah 3s batteries in series i've basically made a 6s battery for $40. Another option would be to buy an adapter(hobby king product id: T-Twins) or charge them separately.
+Eric B oh ok cool thanks. btw how does the rc reciever plug in to anything?
The esc plugs into the receiver to power it.
***** Using my setup, the short answer is no. A 4s battery will only have 14.8 volts. Depending on your motor choice, it may not even work on that voltage. That said there may be a motor/esc/gearing combo out there that will work fine on that battery.
wich program do you use for the templates
+Hugo B autoCAD
Eric B thanks
+Eric B hey what kind of batteries can I get to get 22 miles range?
my motor wont run for some godforsaken reason after trying 3 different esc's
Take it to a hobby shop, they'll test it for you.
Yeah I just did lol it works!!!
+Eric B did you welded motor mount to the trucks or it's a liquid "cold weld"?
mvmedved I used oxy-acetylene torch with aluminum filler rod.
how much does this build cost?
The build can cost anywhere from 200 - 300 dollars. Depends on how much you spend on your board.
Check the description.
if your batteries are connected in series will you have to disconnect the two batteries from each other when you want to charge them?
Nope, I hard wired mine together. Since it gets charged after every ride I wanted it to be as simple and possible. Just keep in mind two 3s batteries in series = 6s battery so it will need to be charged on the 6s setting.
+Eric B would you need to buy a 3s to 6s cable to charge them or can you charge each battery off their own 3s cable
If they are hard wired you need to treat them as a 6s, so you'll have to modify your balance lead as mentioned in the video, once it's done it's hassle free. Hobbyking sells a dual 3s to single 6s balance lead adapter if you dont want to make your own.
+Eric B ah ok perfect, thanks for the help!
+Eric B www.amazon.co.uk/gp/aw/d/B00PBUG4E0/ref=mp_s_a_1_1?qid=1465768716&sr=8-1&pi=SY200_QL40&keywords=3s+to+6s&dpPl=1&dpID=41B8ypp6WRL&ref=plSrch on this 3s to 6s balance connector why does it have the power wire as well? dont you need to connect the power wire from the batteries to the charger?
what board is that? plz
+bendik aarstein Drop carve
+Eric B thank's alot dude, had one like 5 years ago and loved it. need to get one asap.
What size is the motor?
+Finlay Sambrook Smith Turnigy SK3 320
+Eric B thanks
how fast is it?
+IvarGlenna 42km/h
+Eric B woooow
hi eric, nice video.
I have the same wheels which I recognize as the abec 11 flashbacks. and I wanted to know if you drilled through the rubber (the green part) and if you did so, is it stable or does it vibrate? should I buy new wheels for my built? cause normally people do it with wheels that have holes already on them like orangutangs or abec flashbacks or they drill through hard plastic.
thanks
Thanks man. Abec 11 Big zigs, 72mm. I drilled through the urethane because i'm cheep and didn't want to spend hard earned cash on wheels specific to this build. I have not had any problems/ vibration. I also only ended up using two bolts with locknuts and have had no problems. When you put the bolts through the wheel they are pretty tight/secure in the urethane.
