i didn’t even know kit.com existed. Seems like it might be useful for things like this.
Also, i’m happy that its even possible at all now to build an esk8 for $400 even if the deck or other stuff is preowned. It used to be pretty much impossible unless you had access to machines or a real shop of some kind.
Use a silicone sealant to seal your board. It will be fine. And try to use heat shrink on your connections if possible, it will minimize water/shorting damage.
Thanks for advices! For sure l’ll use them
And also, is there any motor mount to 15$ that could fit to round trucks? And can anyone recommend me good wheels (quite cheap)
Fits Paris styled trucks, so may work.
@dickyho 's mounts are 25$ with a clamp ring for Paris trucks… not 15$ but not too much more.
They are 15.50 bucks for the new ones
as @Lumaci @philvanzu suggested. It is actually the same motor mount I mentioned in the list before. Al the part you have in kit.com are sold on HK. IF you use HK don’t forget to add HOBBYKING10 for 10% discount during the check out. Pulley kit you can find on Ali https://www.aliexpress.com/w/wholesale-pulley-kit-skateboard.html?spm=2114.search0104.0.0.643c2ecdfNvUQC&site=glo&groupsort=1&SortType=total_tranpro_desc&g=y&SearchText=pulley+kit+skateboard. Depends which wheels are you gonna use it.
EDIT: Don’t forget, Kapton tape, 5.5 golden bullet connectors, 12 awg wires.
Sorry for not replying, but as a new member i have limited possibilities. To the point. I can’t find other products from aliexpress on hk, could you link me them? And also, I don’t know how to find pulley kit that will fit properly (i know, you’ve linked me it, but I don’t know which one choose. My wheels are 70mm 80a, photo of them is at the bottom. If they won’t fit could you link me good wheels to max 35$? And you said that Filipsky 50a would be good. Could you check if I’ve chosen good vesc? Here’s the link to upgraded kit (Idk how, but i forgot remote 
)

Wait maybe there is a bit of confusion. Aliexpress is one site. HK means HobbyKing which is another one. Concerning your wheels to small for belt drive your motor mount, wheel pulley ecc is not gonna fit. I would say at least 83mm. >90mm for smoother ride. If you use 63xxmm motors than at least 90mm wheels.
Ok, could you recommend me any (cheap) 90mm wheels and a vesc on hobbyking?
and i also changed motor to 245kv version
to high Kv you are at the limit with 10s. Stay with in 200Kv. Wait I will look a combination for you to have good parts for cheap.
VESC: Flipsky VESC -https://www.ebay.de/itm/FLIPSKY-FSVESC-SK8-ESC-W-BEC-FuR-Elektrisches-Skateboard-RC-Auto-Roboter-Q7R8/253751410599?hash=item3b14c33fa7:g:Xi0AAOSwFZtbSbHr (is from Germany, so fast. Ask the seller if can ship to Poland in case ebay doesn’t say it automatically)
HK VESC
Motor
Motor the bigger the more powerful of course. For single at least 6354. I would choose 6374, way more torque for a bit more.
-Used but good parts and you get wheels 90mm ghost from enertion, super motor, pulley, just ask him what you need. For a fair price you are done @ShawnyP https://www.electric-skateboard.builders/t/uk-parts-for-sale-various-stuff-motors-pulleys-enclosure-bms-more-n/65208?u=rey8801
For HK remeber HOBBYKING10 for 10% and choose EU warehouse for cheaper shipping
Always wear a helmet. I didn’t see that mentioned here, but skating on an electric you just built is far far more dangerous than skating on a non-electric you just built. Not just because its fast, but because it launches you instead of you launching it. You have a far higher chance of ass,back of skull streeting. And face streeting on virgin brakes as well.
Also wear shoes, I just did a run out at about 20mph yesterday because of some shit i was trying out. I was barefoot. I can handle that kind of abuse because i’m a professional idiot who hates footwear but generally you should always wear shoes.
Of course i will! I don’t like feeling of griptape and shoes are more comfortable
Also, avoid using large glass bongs while riding at higher speeds. Even if you can get it lit, its just going to blow out of the bowl anyway, probably into your eye, at which point you’ll probably carve violently into the curb, throwing yourself forward and impaling yourself on the bong only to be eaten by racoons and vultures by morning.
what’s bongs?
It’s a large glass pipe for smoking things.
oh,ok, i’ll avoid them
this is epic
