im not 100% sure but i think that the breaking from the motor was because you went fast enough to produced more voltage than the battery was at, so the motor started to generate power. this put a load on it. i believe you were charging the battery.
boat and plane esc have systems to try and stop the motor from moving when it hits resistance. Used when you get stuck in a tree or something you don't want it to try and cut branches.
Thije isThije The board wont want to get pushed(by foot) with a boat or plane esc. This also means you don't have regenerative breaking. Most boat and plane escs don't have brakes so you just slow down by turning down acceleration. I would get a car esc. I would pay the extra $1 for a car esc.
+Jake Abel I see what you're saying but I don't think that's the case here. ESC was cut off from the battery. I think it saw power generated by the wheel as I pushed and was trying to turn back on. When you turn on the esc initially, it generates tones by momentarily energizing the motor. My best guess. So far unplugging the motor does the trick.
Eric B If you do push it will generate electricity turning on the esc and the esc will kick in the not letting the motor turn to protect the motor(usually because it would be attached to propellers). It is a design that is in a lot of board and air escs. Car esc don't have that.
+Thije isThije Boat esc is cheap, weather proof, lower profile and the wires run out the ends. Car esc is usually more of a cube, has better brakes. If strong brakes are important get a car esc. Note that the faster you go the stronger the brakes are with this particular boat esc, and at speed (30kmh+) they work well. If you're going under 15kmh-ish its about as efficient as foot braking.
Nice you did a good job it seems! I'll build mine too, parts are ordered already. :) Just how thick is your aluminium plate that holds the motor? I wonder if i'll have to add something against the torsion as well. And another question: do you think it is possible to put it on the truck without welding it? I don't now how to get access to a welding device
+Noerfi Right on man, lots of fun. Its not very thick, only 1/8th inch, that's why I had to use L channel to keep it from bending. If I did it again i'd probably just rivet two 1/8th inch plates together or go to a metal shop and see if they'd sell me a small chunk of 1/4". With a thicker plate you probably won't have to worry too much about torsional flexing, you can always have a strut welded on after for extra support. Just google welders in your area, if you don't have a torch or welder it'll be much faster to have someone else do it.
I have also build an electric longboard with the same boat ESC, but you said if you were pumping the motor will brake sometimes. I have the same thing but it's only when I'm riding to fast by pumping. Another question, do you have some problems with braking because sometimes my board brakes perfect, but at a random moment it brakes super hard when I hit the brake and I don't know why the motor does that? Do you have that issue to?
As well your don't want to push it manually as a motor is coils with a magnet and by you pushing you are making a current in the opposite direction this is why you add diodes after motors normally.
Nice video dude! Did u had the chance to test and see how many km you do per charge? Also, can u please put a lonk for the balance cable for the 3s to 6s ? Thank you
Range detail are in the description, I modified a regular 6s balance cable, but hobbyking sells a 3s to 6s adapter if you're interested. Enter product id: T-Twins, into the hobbyking search bar. Cheers
thanks man - i think i got one of these 3s to 6s but when i plugged them in together one of the cables just melted - so i thought the connections are wrong. i will look into it. do you know if just hobby kind selling these?
Thanks! Yes there are brakes. They are pretty light though, similar to dragging a toe, but they get stronger the faster go. At 10kmh almost none, at full speed it's enough to throw you off balance if you don't brace yourself.
It would certainly help with acceleration, top speed depends on gearing, I could re-gear mine and gain some speed at a loss of torque. Unless you are climbing massive hills or you weigh 250 lbs I don't honestly see the point. Before I built this I thought about a dual setup but the single setup is more than enough. It goes 42kmh with my current gearing, and geared as tall as it is, acceleration is still very good. You can always add another motor later, so i'd suggest starting with one.
No that was just a cheep 50A toggle switch I picked up. It burnt out like 3 rides after this video. I'm no longer running a switch, but got some anti-spark connectors from hobbyking. SKU:015000177-0 hobbyking.com/en_us/xt90-s-anti-spark-connector-2pairs-bag.html Its a cheep simple solution if you don't want to spend a ton of cash on a loopkey.
hey man nice to see a video like this, watched both parts. So my question is do you think I could do this with a motor from a old electric scooter that a battery died on,it's good because it already has gears and everything and I would just need to buy couple of things to do it
I'm from Ottawa too! My parts should be here tomorrow from Hobbyking, if you don't mind me asking, did you get charged duty fees when the parts arrived? Thanks!
I like the chain tensioner. Get a VESC and the brakes actually work plus can run FOC mode which is much quieter than BLDC.
im not 100% sure but i think that the breaking from the motor was because you went fast enough to produced more voltage than the battery was at, so the motor started to generate power. this put a load on it. i believe you were charging the battery.
Thanks for covering how the board feels when you run out of juice :) Was wondering about that....
boat and plane esc have systems to try and stop the motor from moving when it hits resistance. Used when you get stuck in a tree or something you don't want it to try and cut branches.
+Jake Abel sooo... should i or shouldnt i use this one? because this one is much cheaper than the others, i hope to save some money.

if you had a reverse you might of ben in regen mode and recharging the batteries?
What about moisture, rain and water puddles?
Nice you did a good job it seems!
I'll build mine too, parts are ordered already. :)

Nice build!
Where is part 3? :)
Great video 👍

How much did it cost love the video
Thanks man! Ball park of $300Cad. Theres a breakdown in the description of my build video. Cheers
thx
How does your breaking system work does the speed control read a button as stop
As well your don't want to push it manually as a motor is coils with a magnet and by you pushing you are making a current in the opposite direction this is why you add diodes after motors normally.

i will look into it. do you know if just hobby kind selling these?
"last time i had this thing ooot, it was aboot" canadian?
when you turn what happens to the wohole motor and drive system?
It stays connected to the truck/axle, and stays perpendicular to the wheels, ie. It doesn't move. It's the board that tilts.
great build! thanx for video!!!😉
and what about the brake? does it work?
Thanks! Yes there are brakes. They are pretty light though, similar to dragging a toe, but they get stronger the faster go. At 10kmh almost none, at full speed it's enough to throw you off balance if you don't brace yourself.

how are brakes on that ESC? Are there any at all? I have the same ESC, but 90A version and it seems brakes are very very weak.
+njakts Read the comments below, I talk about the brakes.
Great video! almost done myself.. :]
what type of switch did you use? vedder loopkey? or just a high power anti spark switch?
No that was just a cheep 50A toggle switch I picked up. It burnt out like 3 rides after this video. I'm no longer running a switch, but got some anti-spark connectors from hobbyking. SKU:015000177-0

I'm not familiar with the driveline on an e-scooter, but if you think it looks fairly complete, give it a shot.
Cool build! How much did the parts cost? Because I am thinking about building an e-skate too :D
How much would you charge to make one if possible ?
I don't have time sorry, but i'll take that as a compliment!
top speed????
that thing is awesome!! how did you manage the esc? did you find a chineze or did you go for a eboard esc in stead?
Thanks! Chinese esc from hobbyking. Check out my part 1 video for more info, link in description.
You're from Ontario? If so what area that park looks nice
+Leo Qin Ottawa, lots of nice trails.
I'm from Ottawa too! My parts should be here tomorrow from Hobbyking, if you don't mind me asking, did you get charged duty fees when the parts arrived? Thanks!
Is your board geared more for torque or speed?
+Eekhoornstaartlolly Both, but gearing varies motor to motor
What's your gear ratio? I believe I heard a 2:1?
Raw Khaos Pretty much ~2.1:1 works well for my wheel size. Nice balance of power/ top end.
top speed?
42kmh
wow, nice i wouldnt want to know what happend if you put 100$ posideon motor! (-:
LOL that you had tools on you and kicked it all that way with the belt on. next time take the belt off so it kicks 10 out of 10 ;)
You sound canadian eh
Last time i had this thing ut it was abut minus fuiv ut love that accent man
