Carving up the mean streets of Palmy!
Any interest from the cops?
I'm aiming to use mine as a commute option.....

I've also recently been testing the SkyRC toro 150A. Bluetooth connection is sweet, if you get past the bugs.
Adjustable throttle and braking curves is a must for me.

These small rc escs is not made for longer periods with high amp draw. I also smoke them with reduction but thats in longer periods with acceleration/brake/acceleration/brake.
With your hub motors you are maybe limited to 6S unless you want to gear it for world guinnes record.
Speed fully charged 6S: (145KV*4,2V*6S)RPM *(1/60) *pi*0,092 *3,6=63,4 km/h
Speed fully charged 10S: (145KV*4,2V*10S)RPM *(1/60) *pi*0,092 *3,6=105,6 km/h
My impression on the vesc is that you need to run 10S or 12S to get maximum out of the esc without the thermal protection kicking in. Then you would need lower kv motors.

Not many folks on here have done a DIY eboard with hub motors...so your one of few congrats.... but we need pics for it to be legit...
I think you need to go near 100kv. And also higher voltage Would be better.
60kms is crazy... did you ever ride this fast? Or mostly ride at half throttle.... ? Vedder was saying about riding at half throttle can increase motor current. Vs riding full throttle...
you need a solid ESC.
I can get you a vesc delivered to your door for about $133usd. Or approx $178NZD... so slightly cheaper than you think.. Its about $120USD ea.
What sort of speeds are others aiming for when selecting gear ratios for a 6S system?

Pediglide wrote:Ok. I gotta try this. I actually started trying to disassemble my Sk3 before but got stumped by those small screws that are holding the fan.
How did you remove it without stripping the head? Also, how did you keep the stator from rotating, did you put a keyway?
I think I also remembered you built an e-mtboard, how is it? I saw your E-bike videos, your builds are amazing.
