BARRIKADE: 4WD Hybrid jumper V2 Update

Alright, time for the V2 update; a few component choices have been changed based on early testing, and a few shake tests have revealed some faults with the design. Let’s start with the component changes!

MBS METAL HUBS > TRAMPA PHATLADS
MBS metal cores aren’t compatible with the Apex adapters! Fuck me, right? I’ve swapped over to Phatlads in order to get something that’s compatible, and for the wider wheel!

MAKERX DV4 > STORMCORE 60D+
Buddy needed an ESC, so I helped him out and gave him one of my DV4s, on top of that my daily driver exploded and someone at SDESK8 was selling a 60D+ for cheep cheep so… it now uses dual Stormcores! That said, I plan to move over to MakerX in the near future, so stay tuned!

NOW ONTO THE SHAKE TEST RESULTS

Fucked around: Motors were mounted at way too high an angle, and I took one jump and promptly slapped my enclosures into them, immediately cracking both enclosures off the damn board. Ooops.
Found out: Motors needed to be rotated down.

Fucked around: Front right gear drive started shaking itself loose during a test ride after repositioning motors; oopsie!
Found out Using loctite is important, and I am now in the running for a Darwin award. Loctite re-applied to everything, two gear drives are now held together with 3 bolts. Life insurance policy updated

Fucked Around: Went with way higher bushing duro than recommended, Fatcone 90a and cone 93a all the way around; can’t turn the fucking board lmao
Found out: PKP feel is waaaaaay different than RKP feel; while 90A is usually the lowest I’ll go on an RKP board, the dual bushing setup creates way more resistance than I was expecting. New bushings ordered from @RipTideSports

Fucked Around: Ooooh, there’s a traction control setting in VESC? Let’s turn that on!
Found Out: Traction control disabled. Life insurance policy checked again.


STILL LEFT TO DO

  • Install new bushings
  • Fix enclosures (currently held on with zipties wheeee)
  • Swap gear drives over to stainless bolts and reapply loctite
  • Fix all the throttle issues I am having as a result of swapping my controls around to accommodate shitty traction control (thinking polynomial with match .1 ramp, gotta test)
  • Balance newly installed Phatlads
  • Slime the tires for puncture resistance

Also, here’s the picture that almost gave @ShutterShock a brain aneurysm. In order to get this thing ready for esk8con, I put half an MBS core under each enclosure and ziptied it down. I didn’t have enough time to actually get the motor position rotated, so I rode it at ESK8CON like this lmao
