Hello, have just got into the realm of longboarding and built my own eboard. I have the VESC a 350kv alien motor and flysky gt3 reciever. I tested it for the first time yesterday. It works ok, but i have the following issues:

(In duty cycle mode and bldc mode)

  1. when I let off the throttle i get an annoying squealing sound and the wheels lock up or feels like a brake is on

  2. when I am on the throttle it is not smooth, it feels like all or nothing, large amount of deadband

  3. to get the board going from a standstill it shakes and feels like it is cogging but once it gets going its ok

if you know what settings in the bldc tool would help with these issues please let me know, thanks!

Guys, I’m sure this has been answered elsewhere but I haven’t been able to find it. I’ve just finished putting together my first build and having some belt tension issues. I’ve got the motor as close to the trucks as possible (mount is basically scrubbing the motor) but the belt is still way too tight - can barely get it on there. Any suggestions/solutions?

Setup is DIYES 36/16, enertion mount, 265mm belt. Tried a 280mm belt too but there isnt enough adjustment in the mount.

Pics would help when looking g for advice, and prolly start a thread.

Thanks for the reply. Haven’t got enough reading time to start a new thread yet. Pics to follow

Hello everyone!
I am currently piecing together the parts for my first build, but I don’t know if all of them will work together.
My main concern is the the motor mount kit with the wheels, but I also have no idea about if the motor will fit either. Any help is much appreciated! Thankyou!

Please create a build thread, this isn’t the place to post your build questions

will 410kv brushless motor work with the following specs
PROP - 15 x 8
● Get 3600gms Thrust
Lipo - 6 cell 22.2V
ESC - 60 amp
Power - 3600W
please reply… I am sitting on this for sometime now

New builder? LIST OF KNOWN AND COMMONLY USED PARTS! You should look at this. Can’t really tell you nothing with that information.


#60

Thank you for your speedy reply. I did have a look at that. But I am unable to find a motor below 410kv and I live in India. So I wanted to check if a 410kv motor will do the job.


#61

get a sk3 from hobbyking or one of our vendors here:
Enertion, DIY, esk8.de, unik, Polar, Ollin, …or from someone else.
They all ship international!
Do a bit of research here and you´ll find everything you need!

The rule of thumb for motor is always 280kv or lower with 1:3 gear ratio at minimum. This is by far the safest point to get started. If you buy cheap motor with higher kv, the chances if its not strong enough is that you will need to buy another one in which it will cost you more money.

6 cells lipo ok.
60 AMP esc abit low, get something more than 100 AMP so that it doesn’t get easily over heating.

Low specs for electric longboard works, but it wil get burned down / broken very fast.
These motors and electronics are meant to run 3kg object and not 60kg++
So keep in mind, more torque + better electronics = longer life + pleasure experience.

Hi there community! I’m new to the forum and to the esk8 world. I´ve been skateboarding since i was 7 and just recently discovered Esk8´s! I´m planning on gathering knoweldge and building my own electric cruiser. Looking forward in participating and creating great stuff! Congrats on the great forum! Cheers!

410kv is fine you just have to add more mechanical gearing or lower the voltage (in which case you’ll need an esc that can do more amps to get the same power).
you can actually get more torque from a high kv motor that is geared down than a low kv that doesn’t have the same high gear ratio. the speed of the high kv is converted to torque
