Stary Wanna-Be Using Pediglides Single Hub Motor

mccloed · Oct 12, 2015

So I tried to copy Stary, kinda. The board doesn't look that great from the bottom but it's pretty thin. I used six of the single cell 5000mah from HobbyKing with a BMS. I've only hit 25mph, so far, but there is definitely more throttle to be had. It's only 12.2lbs and I can get about ten miles per charge as long as I don't push it too much. I usually average about 15 - 18mph.

awesome simplistic board!

any pics of the inside? I was wondering how you wired the BMS to be able to use a laptop style charger.

Also which BMS is it?

mccloed · Oct 12, 2015

Totally forgot to take pictures of the inside :oops:

I believe the BMS was from AliExpress.

You're going to smoke the Stary. Btw, its $899 now for pre-order. That's almost double.

Stary only single motor.. Wasn't a work horse though... Do like the 10lbs but doubt I'll end up using it as a daily rider.

Yup. And you won't get it till March, 2016.

That looks like a bamboo board I got from Amazon. It was cheap. Very flexible.

How did you make the bottom, is it carbon and epoxy ?
Can u open it up ever!?
Very nice

I really like the hub motors. Cool build.

Thanks!

I believe it is an 8 ply maple board. Not very flexible until I routed out the center. Then I put two layers of carbon fiber in the routed out part. The whole outside is just vinyl covering to make it look cool. I can open it by removing the vinyl and all the screws underneath, but I kinda made it to commute to work 6 miles away so I would never have to open it. I just charge when I get to work and I'm good to go. I might even be able to get to work and back on one charge. It averages a 1/2 volt per mile.

Nice clean build Mccleod! Simple. Gotta love hub motors for not looking like an e-board until you look closer.

Also interested in seeing the insides of your enclosure and more info on the BMS you used.

Hummina Shadeeba · Oct 13, 2015

Oo.
Board rich with stuff.
I also want to know bout ur bms which enables the laptop charger. Could be really cheap and convenient. How much was the bms and could it do 10s. I was into doing the bms and also looked at them on alibaba and then... Need to see it to make the idea more concrete and feasible.
How's it do with the single motor? With it being still a somewhat high kv do u think it draws a lot more amps and ultimately gives a decreased range compared to a kv that more so matches the top speed? Maybe 6s is better than 10s Because your battery is composed of more amps than volts and that's what it needs. If u can't get up to the high speed the volts enable..wasted energy?

This is the way of the Ninja.... :mrgreen:

psychotiller · Oct 13, 2015

Mccloed is definitely some sort of Irish Ninja. He puts all of this cool stuff together in his sleep and never remembers how he did it! :shock:

mccloed · Oct 13, 2015

This is the BMS/PCM I used: http://www.aliexpress.com/item/A-22-2V-PCM-Protection-Circuit-Module-For-6S-Li-ion-Li-Po-Battery-Current10A-SM519/32308029349.html

I may have to take the board apart anyway. I think I wired the BMS incorrectly according to an eBay listing I found. :? :shock:

So, I'll take pic's this time.

Thanks for the link, I'm also trying to buy a proper BMS for my first build...

However I'm really confused; Your BMS has a current of 10A... isn't that too low? I have same batteries and just one motor, and I was thinking of a 50A BMS... Since I thought that using a 10A BMS means that everytime your motor demands more than 10A, it will cut off the current flow!
Please, if there is somebody more experienced around, give us a hint :roll:

mccloed · Oct 14, 2015

I wired it so I'm only using the balancing feature, I think. I can't for the life of me remember how, though. :?

As @psychotiller said, " He puts all of this cool stuff together in his sleep and never remembers how he did it! :shock:

10 mile range from 5000mah, that's nearly double what I'm getting. How is this possible! Could my belt drive system be causing that much drag? or is your ride completely flat? haha....i'd die for 10+ mile range

psychotiller · Oct 14, 2015

It actually makes sense to me...If I'm running a 3:1 geared system that means my motor is turning 3 rotations for every single rotation of my drivewheel. If you have the same battery/motor/esc/wheel as the sleepwalking ninja your motor may be working less to get you going because of the gearing, but it's spinning 3 times as fast and working more to go the same distance.

This makes complete sense... I now need hubs

torqueboards · Oct 14, 2015

Sounds awesome.. Go HUBS!

LEVer · Oct 14, 2015

Don't forget the awesome coasting distance. If I see a red light about 50 yards away, I can just put it in neutral and coast to get there. This is coming off from a 20mph speed and dual hubs. The single hub has even less resistance.

So, I had to open up this board. A couple of the wires apparently got disconnected. I took some pics of the BMS. I also checked the voltages in the individual cells and they were pretty well balanced(.01 - .02 volts off)

How's the clearence from the motor to the deck when you lean in for a sharp turn? I ask because I was originally looking for a drop through setup like this but couldn't find anything that gave sufficient clearance with these hubs.
