"Nothing Fancy", A Tito Duality truck build

Nothing Fancy is back up and running :checkered_flag:

Thanks @TheSharpergardner @hoytkid @Ac53n for quickly jumping in and offering parts. Ya’ll are great, really appreciate it :slight_smile:

I ended up replacing them with a set of SKP 6355 Reachers from @HAIRYMANJACK

He won them at AVS in 2023, and they’ve been sitting on his shelf ever since.

They’re a lot smaller then the old 6384 Apex motors, but I bet they’re about as powerful

Apex motor not-a-rant

As I’ve said before, the old 190kv motors were previously a weakness of the build.

  • High iron losses quickly led to overheating if cruising 30+mph. I can’t fault the motor design too much for this, however. These are 12s motors that I was running at 20s. When I was faster then 25~30mph, they were spinning at a higher rpm then they were designed to spin.
  • They were sealed motors, so no cooling channels. Great for off-road mountainboarding, not ideal for street riding.
  • Crazy ear piecing resonance 25~30mph. Apologies to my group ride friends.
  • Generally low efficiency (lackluster range)

The only thing good about them was that I didn’t need to use locktite on the motor pinion.

I don’t (really) regret the decisions to use them on the build in the first place…but I’m very, very excited to have some quality Reachers onto this board instead (even if they are “only” 6355’s)

Drive Reassembly

Drivetrain config

I have both sets of motor pinions for the jump drives, 5.5 and 4.4.

Nothing Fancy does NOT need to go 60mph lmao. Easy choice, sticking with 5.5 it is.

Inspecting the motor pinions, they’ve defininity accumulated wear over the past thousands of miles. Plenty more life in them though

Green has come out, no turning back now. Probably should’ve checked that I cut the shafts short enough to fit in the drives before I did this.

I took this as an opportunity to re-pack the drives with new grease. Check out new grease, next to the old stuff

weeeeeeeeeee

after 6 hours of work, the drives closed up with new motors and grease. Flawless reassembly.

Opening her up to re-wire the D100s

And disconnecting the motors from the D100s.
First time the deck has been free from the enclosure since I built her a year ago. Feels longer!

Had to chop the new motor’s phase wires and solder new connectors.

Did these need to be 5.5mm bullets? Definitely not.

Was it what I had already soldered onto the D100s? I plea the 5th.

Because I love crosslinking

Show us ya joints! - #122 by tuckjohn

Added hot glue to misc JST (should’ve done this before)

I wanted to add some cosmetic blue overbraid to the phase wires. Love the colors @Skyart, but I prefer blue :smiling_face_with_three_hearts:

Tried something different this time- before heatshrinking the ends, I put a ring of hot glue under the overbraid. When I heat the heatshink, this re-melts, and is squeezed by the heatshink into the overbraid. Hopefully this prevents the overbraid from sliding out of the heatshrink over time(which is happening
on Ankle Wreacher). I’m pretty optimistic.

Add wiretie, looking good.

Heatshrink the other side

And the two halves have been remated

Do some programming, and we’ve got some wheels spinning babbbyyyyy
80a motor. Was running 90A on the old apex motors

Did some misc cable management, taped the bullets to prevent them from coming apart, —


INTERLUDE
Anyone going to esk8con with a bluetooth module… HIGHLY recommend you disconnect it for the weekend if it’s not password protected. Only takes one person mistakenly connecting to your board and messing with your settings to ruin your weekend. I’ve seen it happen before.
If nothing else… go into your vesc app and check the “preferred” toggle. Will help prevent you from doing that to someone else’s board when you’re surrounded by 100s of vesc bluetooth modules :slight_smile:

Do it or Huey disapproves

Almost forgot to remove mine


(also it’s redundant because of the new Megan)


–and sealed her up. Ready for the con! Woot Woot.

Haven’t ridden yet, waiting for when I’ll be in full safety gear. Doesn’t hurt to be careful with a new board setup (pun intended)

It’ll happen sunday, at the dam. If you’re in Socal, come out and race! More people means more Chaos :grin:
