Also not dead set on the batteries, if anyone knows of any that are better, would have a longer life and more power in the same price range that would be awesome!

I know the esc is for boats but I have heard it works fine for an E longboard. If anyone knows of a cheap car dual ESC that will work for those two motors please let me know, just not trying to shell out 120$ for an ESC right now on a first time build.

Also using 83mm flywheels, caliber trucks and not sure about the deck yet.

Any comments or ideas are greatly appreciated!

None of those links seem to work, something must have gone wrong with the url's.
A lot of people here will advise against anything other than known and tried car esc's.
Beware that buying cheap Esc's will cost you in the long run, they will most likely not last very long.

Fixed the links, do you have any recommendations on the ESC?

Hey BBcane!

You look like you have a good list for the most part.

Motors - 5060's should work fine. Bit long length at 60mm, so if you want dual rear you probably will want a long truck like Paris 195's. You might also consider either dual diagonal, or a single 63mm motor if you aren't too heavy or want to zoom up hills. What's your weight and likely use (flats/hills?)?

ESC - if your budget is 70-80 i'd recommend at least a Car ESC. You do not want a Boat/Heli ESC as the brakes don't work right for boarding (in most cases unless someone has a hacked firmware - and no i don't know any to recommend like that). Also make sure you get a programming card to set/adjust brakes! Usually 10-20 extra. I would strongly suggest you look at either the VESC (check the for sale section - several folks selling, or get one from enertion), or Torque's ESC's are proven, OR one of the "standard" RC car ones - FVT/XERUN, etc.

Batteries - those work great. You have (approx) 100A continuous w/ a 5000mAh 20c battery. That should be ample. (Ah x c rating = amps. So 5000mAh/5Ah * 20c = 100A) Your peak is 30c = 150A peak. I have several of similar batteries that are around 20-25c. If you build a monster draw system it will equal shorter battery life, but i think you are safe w/ a roughly 100A constant setup (where you likely will only draw 50-60A peak).

Charger - did you forget a power supply? I don't see that is one of the "v2 AC" versions. You will need an AC to DC power supply to give that charger 12-18v DC. There are some that have a small laptop power brick built in - usually very slow compared to a nicer dedicated power supply. What this actually equals is slower (not terrible for smaller packs) charging. If you get bigger battery packs down the road your 5-6A max charging is going to equal longer and longer charge times.

I would suggest either getting a decent'ish power supply (i'm a fan of the Dell Server power supplies on ebay that are converted to RC charging w/ 12v out (usually 50-60A!) and are only around $35). OR get one of the AC/DC chargers like:

http://www.amazon.com/Genuine-SKYRC-Power-6Amps-50Watts/dp/B00ND7J38C

Also worth having, but not needed to start - get a parallel charging board like this:

Get the right one w/ your correct battery connectors. What this lets you do is charge multiple batteries at the same time. You connect the single power and balance plug to the charger, then plug in up to six batteries (or just two) power and balance plugs at the same time and it will charge/balance them all at the same time. Instead of charging one at a time (which also works to start).

83mm flywheel or clones - work great! easy to attach your wheel gear.

Motor mount? I'd suggest one of the "kits" from DIYes, Enertion, Alien Drive System (depending on location - US, Australia, UK). I'd recommend the first two from personal experience. Their kits will include gears, belts, etc. Everything you need to install and get going quickly.

Tx/Rx? I'd suggest the GT2b as a great Tx. ROCK SOLID. Just works and is easy. You can later get a smaller 3d printed enclosure and move the internals into the smaller enclosure (Badwolf v1/v2 - see how-to in my sig) which makes it "pocketable".

HTH - GL!

I am very new to this and am not really too sure how the ESC's work, I know what they do but not much more. From the research I have been doing people are saying that I will need two ESC's for two motors but I know there are some ESC's that are meant to support two motors.

Other info I am about 170lbs and this would be used for cruising around campus not many hills but some, not too steep or long but I am looking to make something that can handle more then needed. If there is a better motor then combining these two I would be more then happy to do some research on it. Looking for best options without spending more then 150 on motor and ESC combo.

 

[sl33py]

(mods - can someone move this to the Stand-up E-scooters and E-skateboards section?) That will get more folks to help you out.

Yes, you will need one ESC per motor. Almost all of the dual ESC setups are flier/aps. I would strongly avoid those. Tons of issues. I know Enertion was looking at another option based on VESC but don't think it's out yet.

Your best value is likely the SK3 motors. From a budget perspective, and taking into account you are only 170lbs, i would say your best bet is to start with a single 63mm motor and single VESC! Plus you save the cost of the motor mount, gears, etc. which will save a good chunk of $.

I'm a lot bigger than you at around 260-270lbs, and my GF's single 63mm moves me just fine on 8s. Your use case for mostly flats is pretty ideal for a single motor setup. Then use a bit of the save $ (no second motor, no second motor mount, gears, etc.) and get the VESC! This more than anything else will allow you to increase your voltage as you get more comfortable to the additional power - up to the max around 10/12s (depending on motor kv - >200kv max is 10s, <200kv max is 12s). Some serious power out of a single motor at the higher voltages (like moving me on 8s).

The SK3 6364 245kv should work well! One thing to note with the SK3 motors - they "fudge" the numbers slightly and that motor isn't 64mm long, it's actually 72mm long! Makes a big difference if down the road you wanted to do dual rear (pretty much not possible). You can of course do dual diagonal still though if you find you need more power.

The specs section for that 6364:

Kv(rpm/v) 245
Weight (g) 718
Max Current(A) 70
Resistance(mh) 0
Max Voltage(V) 37
Power(W) 2700
Shaft A (mm) 8
Length B (mm) 72
Diameter C (mm) 59
Can Length (mm) 52
Total Length E (mm) 103

Just good to be aware.

What motor mount kit are you looking at? There are two really great ones from DIYes and Enertion. Either will work unless you need really broad angles to clear a drop deck or drop through (with big wheels! 90/97's maybe?). The Enertion ones are simpler to mount and get everything straight, but more limited range of angles. The DIYes are the most adjustable (and compatible w/ both Paris and Caliber), but the small parts can be fiddly to get just right.

(thanks Spinningmagnets for moving this. I think he'll get a lot more input from folks here than in the general section)

Sl33py is leading you on the right track......I'd second the single motor (63 mm) and the vesc or DIY, and both enertion and DIY mounts are great....I too have both types and can vouch. I would push you towards larger wheel - 83 at least but be warned once you go 90 you want to go back. welcome to the forum.

This is a pretty cheap and works good. Need lcd card though.

Which ESC can I buy for under 80-90 that will work with that and be aruduino programmable.

Hi Guys , i'm a Newbie also, how does going to a larger wheel, 90mm over a 83mm affect Gearing ?

Thanks

Going a larger wheel will increase speed by a bit but most of all why everyone prefer's 90mm is that you are able to ride over bigger cracks and the ride is much smoother. I still use the same ratio for 90mm but you can change it for more torque but personally I don't see the need.

Again, the FVT and XERUN are good ESC's. You will still need to get the programming card (YOU MUST ADJUST BRAKES!). Don't be so cheap that you setup an ESC without a programmer and then can't stop or it chucks you off when you try to brake!

In order to get in the $80-90 range you might have to get one used - i'd check the for sale or clasifieds area here on ES. Or ebay.

Broken record, but for ~$20 more i'd still recommend getting a VESC. Skip a couple coffee brakes or recycle some cans...

GL!

wanted to know if anyone knows if i can get these penny滑板 motors anywhere else? the parts on this site seem to be quite cost effective for the 滑板專賣店 model, or whatever its called, but the site doesnt sell those motor wheels anywhere. any ideas? i cant find these electric skateboard motor wheels anywhere

Timothy2155 - there's a whole thread dedicated to clones:
https://endless-sphere.com/forums/viewtopic.php?f=35&t=65069&hilit=chinese+clones

Your penny board looks pretty cool, but i would really doubt it would work well. Combination of a very small single hub motor, small battery, etc. Unless you are a kid or <100 lbs, and i bet the range is horrible.

The other one is definitely a boosted clone. Read through the "here come the clones" thread and GL!

Still looking for ESC's I want one that I can program an arduino chip to use a wii nun chuck as a controller. Any recommendations would be appreciated.

I'm also wondering what a good AC/DC charger would be for this setup that is under 30$.

I am 3d printing the belt pulley and have the belt, and am cutting a mount with an aluminum bar and attaching it to my caliber trucks.
Any tips or recommendations are appreciated for this setup.

I am slightly nervous about getting a VESC because I hear that it is still in beta stages and are damaged very easily, any other options?

 

[lox897]

Have you looked at Torqueboards 12s ESC?

 

[bbcane78]

I have, I am looking for something around 100$. Would spend 120 if I know I am getting a solid product that will be able to work with a wii remote setup.

 

[NyOliver]

There is an a single part in the hobby that isn't damaged easily, if you DO something wrong.

Put it this way, a 30 W soldering iron is hot right? You wouldn't want to grab it, and when 1500 W comes out of your heat gun, girlfriends blow dryer, that's a crazy amount of energy, right?

You are trying to harness all that power, wirelessly, and vibrating heavily, so if it's a bad design or wiring, mayhem will occur. Your car esc will probably break 1st though. I see no evidence the vesc is unreliable. YMMV.

 

[lox897]

Torqueboards ESC works with the wii remotes but the wii remotes have dropouts which can cause accidents. I would spend the most money on the esc, it's the ost important bit.
