Thanks
cldlhd ! Now I have a basic comparison. This is the 11 x 22amp controller?
Gotta love that 'waterproofing'? I keep wondering: Is the major controller issue really crappy, poorly crimped connectors? The kind that a pin moves out-of-place when you plug them in, so they are making terrible contact to start, and being crimped on not soldered, the wire is inherently making poor contact - until the oxidation generated from the attendant electrolysis of septillions of septillions of little bzzzt, bzzzt shorts oxidizes enough area, changing resistance, reducing conductivity, exceeding the controllers tolerances and triggering "fail" mode.
Nothing but MHO. If that's the issue, the controllers would test bad - but be just fine.
When I changed my throttle out, new twist throttle was noticeably higher wiring grade than the stock 'thumber's'. I have other evidence seems to support, but this is way too long. Also keep in mind I neurotically solder wires and never 'crimp-on' anything, so my judgement's suspect as I could be somewhat 'partial'.
Hey
tlippy,
I have some solutions for "washers" and such.
I'm running the MXUS motor, purported to put out 100nm torque, the 700 has 68nm. You are an orange, I'm a grapefruit. lol
While the risk of spinning your hub is much less, I have some relevant info.
My dropdowns may not be the norm, but we both note the same crooked seating of the rear axle. My wheel does not wobble, but when bottomed out in the dropdowns the wheel's 'caliper side' sits noticeably closer to the frame. I'm seeking a professional opinion.
There's also an issue with the space for the 10 x 16'mm flats. Slop.
I think GRIN had a comment about the common "uneven flats seating" phenomena, re: their claim to fame using their custom MAC T10 with built in torque arm - which seats perfectly level.
Another thing. My (You too?) bike's automotive style Lug-Nut's extremely coarse 'teeth' are not well received on the forums I tend to respect as 'the God's of E-bikes' - like
https://endless-sphere.com/forums/ . "Great for a Dually Chevy 1.5ton 4wd's Steel Wheels, but not for E-bikes" is the read I get.
When using Nordlocks, the fine side firmly imbeds, so a smooth lug nut having the most surface area also has the best holding power.
I ordered these:

M12 x 1.5 Titanium Flange Shoulder Hex Nuts Grade 5 Ti 6Al-4V. Smooth surface for a Nordlock's fine teeth to imbed into.
My bike spun the hub and - as addressed elsewhere - I've installed torque arms using Nordlock washers. I recommend them. That's my opinion.
These photos are not my opinion.
_163102 (top) washer is stock. Note the wear from contact friction. How much of the stock 'pressure washer' is actually making contact?
The other (bottom) is the Nordlock replacement ('fine side' that faces frame dropdown).
_163213, (left) shows the other side of stock lock-washer (that's the contact after torqueing down to 60lbs) and (right & bottom) the two part Nordlock (coarse side) interlocks.
_104218 shows TA installation - caliper side. _104201 shows TA, derailer side - sufficient axle length.
_131437 and _15003shows the damage done by spun hub. That's the "14mm" side of the 10 x 14 axle, jammed into the space that should be 10mm. Thing is, that dropdown is way too large even where only the paint was flaked off, the flats are like 13mm.
_070519 show TA's, imported from British source. 5mm stainless, laser cut (Happy to re-post source. I promote high quality, cottage industry).

To align the wheel, I tried aligning the axle in the dropdown and torqued down. WARNING. This eliminates being able to 'pre-load' axle flats on one side. You lose 50% of your innate holding power and given the slop I found being "V" shaped, if your washer's fail, the axle can work back and forth.
I have 'telltale' marks I punched in place. My axle moves, I know at a glance. I torqued down to 60lbs and within 20 miles it began to spin in the dropdown - again. GRRRRRRRRRRRRRRRRRRRRRRRRRRRRR.
So, I said hell with it and went nuclear, 'double torque plates" suitable for a 2 - 3000watt machine, with Nordlocks, fully pre-loaded axle and torque-arm, and if I sense any flex, I have a little 'cap plate' part designed and ready to be cut to top the arm connector in _104201 for an inflexible mono-structure and at that point, the bolts become the weak point, but those too can be changed out to 'supertanium' grade 20x stronger and now we're talking 5000watt bike w/ custom Steel Dropouts bolted to the frame via welded on Aluminum blocks.
Anyhow, I wander ... Reassembled, kept an eye on my 'telltales', looked good and 250 miles later disassembled. The axle had not budged. It pretty much can't. LOL.
Your axle should easily accompany using Nordlocks on both sides, but if you do, consider some flat lugs as well.
They're M12 1.5 type, or reply and when mine arrive I can post if they were right.
I'm interested to know your thoughts on adjusting/ filing the dropdowns to point that wheel straight?
My rally experience, we called it "doglegging" when front and rear didn't align - Oh the frames I bent - even rolled - and finished reasonably well. Great fun. So having driven thus damaged car's hundred's of miles I know effects: wearing the tires out quickly; reduced control; oversteer; understeer.
"But a 20 - 30mph bike?". Well, that's how I do everything. Why not?

Notes on 'turning bike upside down to service':
Not sure 'bout other bikes, but on the Limited you can easily damage components and it's a real pain to loosen everything up, then adjust and retighten down.
Also, after installing a twist throttle and mirror, I had to buy risers for my GoPro, Light and Display. I couldn't even get the stock stuff on the stock bars + a mirror. It 'kinda' fit; the light was too low; the display sat crooked; etc. Not my style.
The bars have tricky bends. The riser in the pictures (I have several types) and any with two stems must be loosened at all 4 corners. A real pain to get reinstalled perfect.
I said "forget it", bought a high quality "V" kick stand (See comparison with cheap, Chinese model) from Italy in photo _152852 and have limped along, but I'd prefer upside-down for major service - thinking 'bout some blocks.

I'm still searching out a suitable 15amp nominal controller (for 750 x 1000watt Ltd's MXUS) that will work with our KD218 displays.
Is there a special protocol? Why "KT" types won't interface, or will they?
I'm wondering what will interface and not afraid to spend a little finding out.
Any leads would be appreciated !!!
Regards and Ride on !!!
