I’ve been scarred by my relationship with esk8ing.
My first build:
Three years ago I built an esk8 comprised entirely out of parts from Taobao, the place where the shelf life of its components are almost as long as the shits I’ve taken after eating copious amounts of Moroccan lamb curry. The build was documented on the now-defunct builders forum, thus I have @SeanHacker and @longhairedboy to thank for opening my eyes to the friendly, hospitable and loving community that this forum is! (Pls can we all get along I love you both lets just all have a few frothies and fuck ).
In reality, the final build did last slightly longer than my mangled digestive tract, but in actuality its short lifespan was due solely to the BMW wanker that ran over my board… The only real damage was a crushed PP pack, but the blow to my motivation was enough for me to let it sit on the shelf like some ugly ass childhood teddy bear that deep down still held some emotional value.
I posted it to the battery builders thread just for shits, everyone seemed quite content to roast me and my use of duct tape but failed to comment on the banana surreptitiously held in place for later consumption. I also intentionally just threw random shit on top and around it to make the photo and the build look as fucked as possible. I think it worked lol.
The fuck up:
Which brings us nicely to the present. Three years on I haven’t since eaten lamb curry, but my desire for that glorious euphoria that is esk8ing has never left me. Like a shot up coke addict that’s long since ran out I rabidly searched for the quickest fix I could find. I caved… I bought an Exway X1 from my local dealer… Well let me tell ya, turned out the bloody thing was DOA and after a few weeks of back and forth fuckery the dealer rings up and explains that the only option is a refund. Well Fuck.
Hence this thread, fuck buying a house and fuck investing in bitcoin, imma build the sickest rig and I will be so damn happy in 12 months time when it’s finally finished. (I reckon a vaccine for the Rona comes out before my 110’s actually arrive in Australia though…)
Choice of Parts:
Currently I have no damn clue what type of esk8 I want long term. On the one hand I want something soft and carvy, but at the same time I want the option to be as stable as possible above 50 km/h. I already own a Loaded Vanguard and was planning on using that, but as far as I know, only 2 piece enclosures exist off the shelf, that would limit me to (only) 12s4p 30q’s, meh. That’s when I saw @bwahl602’s thread and an eboosted Sportster seemed like an absolute dream! This picture also got me quite hard… seriously it’s so fucking gorgeous! (hope @bwah doesn’t mind the repost, will remove if requested)
In my previous Taobao build, I comfortably rode 50 km/h the majority of the time on paris clones and a snapped plywood deck and I’ve always yearned for more speed, so the RKP’s seemed like a good choice.
Some of you may remember the user whitepony from the previous forum. His most iconic build involved a single drive build on a DIY bamboo flexy deck. His building prowess and carving videos totally mesmerised me at the time and I’ve always wanted to build something that would serve the function of beautiful flexy carving whilst remaining speedy. This deck I envision will serve that function and down the road I may yearn for more stability, at which point I’ll transfer everything over to the eBoosted Switchblade.
Mounts + Pulleys:
I’m not sure whether I want urethane or Pneumie’s long term, which unfortunately rules out the prospect of gear drives. Initially, I was planning on going with 3DS’ Urethane Nano gears but that would mean I’d need an entirely different setup if I ever wanted the option to switch to pneumatics down the road.
Regarding mounts and pulleys if anyone has preferable suggestions on what they believe is the best option I would love to hear them! Currently I’m looking at @xlta mounts and @torqueboards Kegel pulleys. @Psychotiller also has SR RKP mounts but I can’t seem to find if they are available right now. The TB Kegel pulleys look fine although preferably I would find something that doesn’t require bolts and two-side plates to secure. Personally this design simply isn’t seamless and also looks less polished.
Went through @XTLA’s thread and later that day caved and bought a set of his latest extended design motor mounts. They cost a pretty penny (comparatively) but look ABSOLUTELY GORGEOUS and provide the most flexibility in mounting configurations. Faaak yeah.
This is a no-brainer in my book. @Blasto, @Deodand and Lacroix working together is the fucking dream team baby! @b264 I’m sorry mate but your obsession with single esc’s and separating every electronic component for ‘redundancy’ doesn’t fit my ‘real-world’ narrative xD The market has spoken and everyone wants integrated systems which are self-contained and work seamlessly out of the box.
Originally I was going to purchase the Maker SV6 because it seemed like great value. But adding an anti-spark and a bluetooth module to that equation actually adds up to more than the price of the Stormcore! Can’t wait to try this baby out!
Admittedly I have two Maytech vesc’s (the ones that cost like 50 bucks…) from my bao build which still work! So in theory I could still use those. By all means crucify me after I say this, but in all honesty in the three weeks that I rode the bao board (40km a day) I never once had a problem with the Maytech vescs at 40A battery each. They worked like a dream and never got hot even geared high, I guess being on 10s and BLDC helped lol. But with such positive first experiences I’m imagining the Stormcore at 12s to be a completely different beast! (And it better be because bloody hell it costs over 500 far dinkum dollarydoos to get it down here).
Battery - Molicel P42A:
Standard affair here gents. Just stoked to have over 720 whr in a single stack flexy enclosure! Alan you crazy man I love you <3 Still undecided whether or not I make this myself.
Decided to go the DIY route and spot weld my own 12s4p flexy pack. I will document every step of the process here for clarity and feedback! I’ve purchased 52 Molicel P42A’s from Vapcell @ 4.70usd/cell. They’re an authorised Molicel distributor and are apparently “approved by Mooch and HJK”.
They don’t list the Molicel or its price on their website so email them for a quote and an invoice if interested, so far they have been very pleasant to deal with. Eva from Vapcell usually responds within 1 hour or max 24 hours and customer service seems good so far. Will update when batteries start shipping and how long they take to get here.
Often not covered in many build threads but can add up to a significant portion of the cost. In my mind the RD6012 provides the most versatile solution. Charges with CC/CV and can monitor cell charge rate and overall voltage over wifi. There is a greater risk of cell damage and explosion due to user error if the charging parameters aren’t exactly set correctly, (banggood even mentions this). However that being said a VPSU allows finer control over charge voltage and current and can ultimately lead to longer cell life if more conservative voltages are selected.
Would love any and all input you have! By all means even if you comment just to tell me you hate my guts that’s fine, all are welcome I’ll apologise now for this whole thread being unnecessarily wordy Brevity has never been my strong suite, combined with a tendency to over-exaggerate this hardly bodes well for a potential reader 💁
Currently ordering everything along with the therapy sessions with my psychiatrist to work through the sudden drop in savings
