Don't wind him up he has enough motors, controllers and Lipo to build a ride called Drago that will be pure evil and kill and him on a friendly test run, then I'll have to fix it while listening to Vince dicola and home my skills Ice racing in the depths of the russia so i can then ride it and break...

The hoverboard wheels are surprisingly powerful for their size, the torque they have is plentiful I've pitched about with one on a flipsky vesc 6.6 with similar speed results as yourself but I can adjust the phase amps and increase the torque so they are on their limit nearly tapping out and even th...

i don't have a outrunner yet. Should I say F it and build the 650 instead ???? Get a revolt rv 120 pro w/ hall sensors and all the custom stuff you told me to ask for and I'll make my goal 60mph instead. It's just that I've built a e300 before but oh well I feel like the bike would be way more fun ...

I spotted Liitokala, they have some cells that come recommended by use with other ebike riders theres a 21700 imr chemistry 4000mah and 40amp max and 20amp continous and they can be had 6 for $20 so a diy pack of them would be fairly cheap, powerful and fit to what ever shape you fancy. 54mph is fas...

Like mentioned, All vesc manufacturers are missing a trick by not building a 20s + capable vesc, the 6.6 performs faultless and the software just adds some icing on the cake, I believe a 36 fet 150amp continous 250amp burst, 24s capable, 120v absolute max fitted in a small ebike controller case with...

:bigthumb: The wiring looks alot better now its got alot going on buy its much better appearence wise, have you seen the braided sleeving that gives a profesional finish. Its a damn pitty the vescs fall just short of your power requirements for now ive seen a 16s vesion bit it was ££££££, the gps an...

Not spoke or posted for a while i finally had my op and im on the mend ive been in a massive hole of pain but im climbing out of it in the end i had 8 teeth removed and my jaw bone exposed so my lip and tongue didnt lose feeling. Ive been potching with my vesc to test its software out and be honest ...

I meant as the vesc evolves it like the raspi it gathers better hardware and its software is open source to be fully customisable so video overlay is possible with datalogging and its also capable of running codes liked mentioned for adjusting what adc controls do etc, i dont know the software or ho...

From what i understand the vesc 4.12 has only two phase current monitoring shunts so foc can be used but its stability is less than the vesc 6 with a shunt per phase for current monitoring. When in foc mode the controller changes from 6 step comutation to 18 step so the frequency the fets switch at ...

sweeeeeeet.

theres an antispark switch smart from flipsky that detects motor movement and or throttle input and powers up accordingly, you would have to disable your antispark and just fit this it can then turn on or off multiple escs so a 4wd mobility scooter with hoverboard wheels would have foc, traction con...

Which mxus motor you rocking? I am at 36V (10S) with mxus 3kw, its alright, but I am using more discharge current to get same wattage of a higher volted battery. I will be converting to 15S for ease of converting, easily change my LVC to whatever I want. 20" wheels are the key to torque I got a gen...

I wouldn't go tubeless unless the rim is designed to without sealant, there should be a raised lip on the outer of the rim like a cars alloy cross section, the tyre bead should make a poping noise when aired up on to the rim, if the rim is not suitable use a tube the cowboy hacks are pointless speci...

The new 36fet dual 6.6 can go up to 100amp continuous each channel, A well thought out rewind of a 205 45h hub motor like a mxus 3k for example to 6 phase could give 84v 100amp performance on 48v 200amp, it will kick like a mule and go like stink top end. Lipo be wise for a cheap build to get the su...

I've got an a2b axle, nuts, torque arm, matching alex rim and spokes, I would give it away for free but I have asked about the lebowski board and got no where and ended up buying a inferior vesc, I asked about an emax scooter you had for sale saying I was after a cheap hub and you assured me you was...

I got to agree with chalos on this one, belt drive needs to be finely tuned to get the best out of it and that belt system shown above looks like a car fan belt and we have all heard them slip and squeal, The gates drive belt has kevlar added for increased strength and the ribs are across the belt t...

Without multiple testing to destruction we don't really know where the repeatable failure points are, max stall torque and max/power at a given rpm. I watched a guy use a Lego motor maxxed out for a toy lifting crane, he mapped its torque on a graph vs volts with 10 second burst until a failure occu...

I think water ingress would need to be looked at ebikes take some serious off road abuse, I'd suggest the use of a conventional controller case to keep the price down and add your own touches like the sabvoton controllers, uses terminal blocks for the phase and battery termination and then a multi p...

Top man thumbs up on the finer detail,
Don't rush on a vid if your up to your neck with life the explanation given is appreciated.
Good luck with your ride.

30% extra speed took around 200w extra. 50% takes almost 400w on the 6374 I had on my bench. Probably not very accurate numbers as this was a calculated value from duty and noisy phase current reading, not battery shunt. I did my commute today with the "automatic" field weakening. It worked quite w...

I'm fed up of opening browser and the news feed is Tesla bashing crazy, Its the same old elons calls man pedophile, Tesla stock this that and the other its obvious the people up top have spent money trying to convince me he is evil in many ways, I don't really give a toss the guys the otherwise of t...

I would have thought coming from vesc you would stick with what you know at 48v or 13s a vesc could cover it, flipsky got a decent 6.6 out I just got my hands on one myself. I'd get just a front wheel if that's what you want open it up put a kty83 temp sensor in the windings and have lovely little s...

A guy named Sam decok and his clang verbally attacked me on the ES Facebook page for explaining field weakening with similar info as stated above. They wanted to know why a hub was not making anywhere near its no load speed and I said it needed more torque to reach its no load speed it could be ach...

Did you keep an eye on the current ?
30-40% is a lot did you test it unloaded ?

Top work on the coding, can you do a how to utube vid to show your skills, damage at you own risk type of deal.

Just got a vesc for a brushless scooter and will be using a galaxy s4 as the main display and thanks to your app i can have all my Santa wishes at once, truly thank you for putting in all that effort and time with time vesc.
