you can use regular skate bearings and an 8mm shoulder bolt. you can get super low profile ones…
these have a 4mm head…
and they are pricey. but the bearing part is easy.
or you can get odd sized bearings 6x22 and just use M6 bolts.
what is the same.
Deck. Demonseed 42.
Enclosure. Psychotiller Altar wedge. (fresh coat of bed liner)
Battery is a 12s4p 40t on the Duck Batteries PCB with LTT smart BMS.
Unity. back to 23.64 on this one. no power button still.
TB 110s 72a.
3d servisas 44 tooth/15tooth.
TB 218 hanger in the front. BN220 in the back.
what is new.
BN adjustable baseolates.
adding that 16mm of height…
I kind of feel a little sad about giving up on the super low low ride.
but it was just silly as the enclorure could scrape on light road bumps.
so up high I go…
running 40/50
Flipsky 6374 190kv BH motors. these were on the Llama for a minute and have low miles they did get beat up. but run fine.
I have stripped one of the 4 mounting holes on each of the motors. so that is super fucking annoying.
BN XL mounts.
I love the beefyness of the construction.
I don’t love the look on the Demonseed.
the angle is not great… sticks out too much.
I wish I had longer belts so the motor would be further back…
yada yada yada…
im going to get the New BM Mounts to put on here when I can buy them here soon.
today I took my first real morning ride.
like wake up early and go ride first thing.
it was around 7:30 and it was nice and cool out.
did a 25 miler on the flux.
I had put the drive together a while back.
my hang up is that I wanted to clean the battery up a little bit.
this was the first pack I built.
a 12s3p 30q with LTT BMS.
the balance wires werent taped down really well.
so I retaped and also taped the pack to a sheet of abs to keep everything more still…
so somehow from testing it on the bench to the wrapping it all something got fucked up…
motors were spinning in the wrong direction major stuttering.
all kinds of crazy…
I swear it seemed fine on the bench.
I run detection and seems fine but then the motors act weird.
I flash the vesc tool.
rub detection. that looks fine.
and still the same issue.
I flash 23.64 back just for shits and grins…
and same thing.
so I start cutting shrink to open it up and unwrap my tight little package…
and get this.
in the process of taping the unity and wires down
I FUCKING PLUGGED THE SENSOR WIRES I THE WRONG FUCKING SIDE…
I mean. what a dip shit
anyways fixed now.all good…
ran out or the heat shrink so just some gorilla tape should do…
did close to 12 miles.
it ran well.
only went back home at first to change a bushing.
the tiny motors are able to move me.
and they are able to stop me.
they did get really hot to the touch…
I don’t know when that becomes a real issue…
I set the Unity at 45 and -45 motor amps.
Flipsky has 35 max on their website.
when I ran detection last night using the vesc tool it suggested 33 amps…
so hopefully 45 amps is ok…
this is not the fastest or most powerful set up.
but I was not mad at it.
I wasn’t rocketing up hills like most other set ups.
but it pushed me along quite well on flat.
the turning felt pretty good.
the short wheel base is fun for csrving.
but definitely makes me not want to really go super fast.
the super flat deck did not seem to be an issue for just riding…
I didnt try any tricks besides going off curbs and manuals.
I think the flat deck may make it extra hard to Ollie.
All their enclosures seem to be pretty high quality, they’re making an effort to check all the boxes of a quality board which is nice to see. Cool that it fits a unity!
I really did a crappy job soldering the sensor wire extensions.
I used 20 awg which was probably not a great idea…
but in inspecting the problematic side I was able to break the wire on the solder easy on three of the little wires…
why do they use such tiny wires anyway…
so I gotta redo the sensors and the cable sheathing…
I was just talking about this yesterday. One of my sensors went out on the space invader the other day so I just turned it to sensorless and haven’t been bothered enough to go back. Time to check out HFI I guess.
