cool thx. I heard something hit my deck after climbing a hill and my board powered off. it turn back on with no problems no visual damage but i was pretty close to cutoff end just wanted be sure that cutoff end does not mean power down which i knew already but it was one of those āwhat da hellā¦I wonderā moments.
If I use a Battery with 60A Max Discharge with two 4.12 FSESCs running solo with split ppm (by using two receivers), do I want my battery max on the VESCs set to 30A each, since Iām running them in parallel? Also, how do I choose the right battery minimum value and max/min motor value?
Battery: 10S3P 60A discharge
VESC: 2x Flipsky VESC 4.12 50A continous
Motor: 2x Flipsky 6355 65A Max
your logic here is sound
i would want to know what cells are in your pack before hazarding a guess
how many n00bs does it take to make a quorum?
Ive used plastic wrap (cellophane) before to help shape the JBweld around my VESCs in my enclosure, but has anyone tried to use plastic wrap with silicone?
Iām thinking the only way to compress the internals of my enclosure to give a proper seal/flat top to the silicone I pump into the enclosure is to bolt it to the deck, but I donāt want to mate the deck and enclosureā¦ Id rather it be two pieces
What materials have people used to help squish silicone down without it sticking to the opposite surface?
start hereā¦ there is a bit on catalyzing siliconeā¦
Too spooked to use water in it but Iāll keep reading
not water IN itā¦ water on your pressing agentā¦ and anything else you donāt wish it to stick toā¦
welpā¦ there is my some and total knowledge of catalyzing siliconeā¦ iāll let others converse
I got a quick question.
If people have issues with max erpm braking/lockup, why donāt they set much higher erpm limits if their esc can safely handle a value much higher than it is set to?
If their esc canāt, why not just limit your max duty cycle in ppm to less than the 95% so that you never hit the limit, and fall at 35 mph?
I would like to prevent a lockup mid ride as much as possible, and my understanding of erpm and how it works in your esc confuses me.
Would love to know more about this
Imagine your board hits erpm limit at exactly 20.00km/h. Now imagine you set all those limits you say. Now go down a steep hill that would get you to that speed even with brakes engaged and youāll see why it gets scary and fast
Is there any support at all for tizen os? Any app, bluetooth module? Anything at all?

Split PWM (āPPMā) is one receiver. Dual PWM is two receivers

I already asked this before think but forgot to bookmark the answer and nothing shows up when i use the search function
How does one find the KV of the motor if you donāt know it? i believe there is a way to do so on the vesc tool? I also think there is a calculation you can do but i forgot.
@MysticalDork @stan @wafflejock @Deodand
divide or multiply the erpm by the pole countā¦ or something equally arcaneā¦
Run the motor up to maximum unloaded RPM, measure the RPM (vesc tool can do that) and write it down, as well as the supply voltage at that RPM. If itās ERPM that youāre measuring rather than physical, (I canāt remember which one vesc tool reports) divide by the number of pole pairs in the motor (usually 7 for our outrunners). Then divide RPM by voltage, and you will get a rough idea of the KV.
Thanks!
I have 4 motors, i know 2 are 170kv the other 2 200kv, i know that the latter is lighter, but just wanted to make sure since they have no markings on them so we donāt know which is which 100%
