Building a updated suspension board
I wanted to build another suspension board but witha larger tire as the last two models used a Burris Pint tire on a Pint wheel
Unfortunately space for a larger tire is at a premium as the swingarm takes up a lot of space if I wanted to keep the XR form.
The best I could do was a Burris 11 x 5.5 x 6 tire on a Pint wheel, even at that I had to use a set of extented rails which are 5/8 inch longer.
With the experience gained building, improving, vesc'd and riding, I can confidently build a much improved model.
The added aluminum plates under the footpads really stiffens the Xr style chassis, the wiring is hidden and goes around the right side delrin swingarm bushing and the rail will be milled out to allow the wire harness to pass through, it's a proven concept. -
Gen 1 suspension board revisited
On my gen1 suspension which is Xr controller based, I had a strange buzzing on "delirium" mode while moving almost like harmonics, but quiet on "mission''.
I thought it was the brass swingarm bushings and I changed the brass for delrin plastic bushings and the harmonics are still there .
Since the motor is no longer used as a cross member to tie the rails together, the rails are only tied together with the plastic controller and battery box, which results in a weak chassis, torsionally.
I also used a Kush front footpad which is very flexible.
The solution turned out to be a .125" aluminum plate to tie the rails together with 4 extra 10-32 screws to stiffen up the rails, all buzzing is gone on "delirium" , my gen 2 had no harmonics as it uses Bash bumpers which have extra brackets that stiffen up the rails.
Now I can incorporate plates for the front and back in my present models and in the next design which may be dual shock for "clydesdale" (heavier) riders.

Adapting a Superflux to run in a XR, GT and maybe a GTS(not tested)
I posted on FB too
Requires a moderate skill level involving a bit of dremel or machining, and soldering.
Parts needed 3 x 41f hall sensors, OW hall pcb board from a HC stator or a Pickles hall pcb. I have not tested The Pickles hall pcb, I used an OW one. I also used JB weld to pot the 41F halls and custom axle blocks, but aftermarket axle adapters are available. Wiring has to be custom made, in my case, I bypassed the stock GT motor connector, used 12 gauge phase wires with bullet connectors and custom hall wires all coming out the side of the controller box.
That's just one way for the wiring, the stock motor connector can also be adapted, but I didn't like the wimpy stock connector.
Very important, you must switch the yellow and green phase wires.
I have tested this mod on Xr, GT, and Vesc, I have two SF motors modified this way and have performed great as this mod minicks a HC motor but is more heat tolerant.
I have not tested this on a GTS as I don't have a GTS.

A word of caution about vesc/controller capacitors
I have a Thor vesc in my 20s2p board and it always had a inconsistant shutdown with the momentary switch.
A new firmware just came out from Surfdado to retify the shutdown problem, I always use usb to update vesc firmware and BT for other changes, since I had to open up the controller to plug in, I found a capacitor lying at the bottom pf the controller box.
After disassembling the vesc to solder the loose cap back on, I went to plug the cap back in the cb, the loud "crack' and spark that jumped really woke me up to say the least.
That loose cap stilll had a charge even after at least 2 day since I rode the board, so always assume a cap is charged!
Luckily, the Thor was lid mounted and the cap didn't touch the vesc circuit board, I resoldered all the caps and hot glued the caps together.
Unfortuneatly the new firmware with the bulletproof shutdown didn't work on my Thor as it was a prototype that I was charged full price. -
RE: DIY your onewheel with BMS
@jack-yang I have a couple of Maxkgo bms's in my builds, the Zbms was always out of stock. the Maxkgo work fine and balances the cells nicely, the only downside is the balance wires and the jst ph connector as they are made of low temperature materials, very easy to melt with a soldering iron, doesn't take much to crush the balance wires. I recommend they be replaced with quality wires .
I had a couple of evaluation "Pickles" 15s and 18s drop in bms, but they never charged the cells above 90% and two 18s-20s bms, but those two instantly "smoked" upon power connection. I'm pretty sure I fallowed the hookup sequence. -
RE: Hacksmith's fuel powered Onewheel
@lia different thinking !
I can carry this and plug in a charger ion my plus. Haha I -
RE: XR rear LED Pinout
The red leds use orange for positive and grey for negative
The white leds use yellow for positive and magenta for negative .
I'm not sure you can use the Xr rear light strip for Thor as I believe the Thor light controller is for rgb(w) . -
RE: Ubox100 XR and Pint build
@notsure I would like to, but 100 v vescs are limited right now, I think the Tronics x12 is about the only choice @ $450 us, too pricey at the moment.

RE: Ubox100 XR and Pint build
@lia I redo or update some of the builds, but I have 6 ready to ride at a moments notice , 4 in storage and a whole bunch of Pint , XR controllers.

Ubox100 XR and Pint build
Finishing up a Xr and a Pint Ubox100 controller box. I just used front headlights from a dollar store wall light 3v, and they are potted in industrial epoxy.
The gland adapter is custom machined .778"x16tpi, unfortunately, the shine will tarnish under the footpad.
They will be 84v builds.

The vesc ante just went up
Just as I'm finishing up a 20s Ubox100 Pint X and a Thor 20s XR now Tronics X12 30s vesc is coming out.
My 18s Ubox100 GT will be upgraded with the Tronics X12 later this year to how many batteries the GT battery box can carry.
Pickles is prototyping a 18s- 30s charge only bms now.
Great time for me getting back into vesc after a year layoff.

Thor vesc in a Xr/Plus controller box
Thor 300 fits nicely in an stock Xr/Plus controller housing.

RE: FM are selling parts!
@lia Prices are really reasonable too, cheaper than used parts.
