This is a build that’s been working for about a month now. I call it Thiccn’t because it’s fairly sleek but relatively heavy, just enough that it’s a pain to carry around campus when I have to be social and walk with my friends. At least I have an excuse to start another build (jk, I’m starting 2 more cause why not).
There was actually a previous iteration that was using Hummie v2 hubs, but I think their mileage finally got to them (I was at least the 3rd owner) and they were having overheating issues even though I’m 155 lbs fully geared.
So I opted to replace them with a reasonably powered satellite motor drivetrain using racerstar 5065 200kv motors that I got from @hyperIon1 and mounts from @marcmt88 with a gear ratio of 15/38. I’m running sensored FOC with 35/70 and -10/-65 on each focbox, although I change it so often that those numbers are probably wrong. It’s working flawlessly on one motor, the other motor jitters inconsistently because of reasons I have yet to pinpoint. Suggestions are welcome!
Here are the pictures (parts list below):
!Yes, the enclosure is crooked cause I’m an impatient person. Yes, I fucked up the drill holes for the inserts in the deck and the holes in the enclosure cause I’m an impatient person. And yes, the battery has a patchwork of fish paper because I had to go in a bunch of times and check cell life. I recently redid it and it looks much cleaner. I also taped down balance wires probably, don’t remember. All parts inside the enclosure are velcro’d down or glued down depending on when they were installed and when I ran out of velcro.
Side note: I ended up JB welding the motor mounts at their final angle as I couldn’t get them to stay properly angled without drastic measures. As such, the motors are the only thing I can change. I wanted to try surf-rodz anyway .
Here’s the parts list:
- Hummie deck (the older version with the 140mm cutout)
- 2x FOCBOX
- 2x Racerstar 5065 200kv from @hyperIon1
- 15/38 gear ratio, wheel pulleys from @marcmt88
- TB 218mm trucks
- ABEC 11 107mm superflys with zealous bearings
- @psychotiller Arc v2 enclosure
- 10s4p 30q battery built by myself using cell level fusing and spot welding, discharge bypassed
- hm-10 bluetooth module from aliexpress, courtesy of @Winfly
Also, some local people have been curious as to what my lights setup is, so I’ll just lay it out here in case someone else is. I used 4x sk98 clone flashlights from Amazon and mounted them on top of my trucks using .75 - 1.25 inch bar clamps (also from Amazon), 2 for each light. For the rear lights, I also jb welded red filters to the lenses. This can all be done for much cheaper than I did it, but I used Amazon because, again, I’m an impatient person.
Heres the link to the lights - note that these don’t come with spacers so your 18650 cells will bounce around unless you make some yourself: https://www.amazon.com/gp/product/B01IQMIFR8/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 the clamps - a bit pricey for what they are but pretty beefy: https://www.amazon.com/gp/product/B0791NB4FM/ref=oh_aui_detailpage_o09_s00?ie=UTF8&psc=1 the filters - also pricey for what they are: https://www.amazon.com/gp/product/B00X3J8KEI/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1
This build is basically in its final iteration because I have too much money spent and/or planned on being spent in the near future on this damn addiction. The only thing to do is to rebuild the battery as I think I have at least 2 dead cells. 2 of my parallel groups refuse to charge above 4.1v (on 2 different BMS). But I have a cells coming in so I can do so with very little down time on the board.
