it’s been a day since I rode my painkiller, and I already somewhat regret the 6kWh bringing up and down the stairs.
also, I still have 4vescs laying around (2x cheapfocer sprusa edition and a teenka), so I’d like to build something lighter
thinking 12s6-8p 40T, small motors (either SK3 5065 236kv or RTS5065 190kv), metroboards pneu, the redember 44 I’ve laying around… could be way easier to handle
now, I have no clue in the drive. I’d like to try belts, as I’ve had only pain with them on 2wd, but I hope the skipping will be resolved on 4wd. however, I’ve not been looking around the comunity and the parts market for a while, so my question is, what kinds of short mounts are there nowadays? (that could fit the motors under the deck with ~16/66 pulley setup). or what other options do I have?
If you have a redember then you don’t need super short mounts, surely? If I were you I’d look into using these trucks and mounts: (I think you can forward mount them)
alternatively, gear drives would work to keep the motor close to the truck. BN ones are cheap enough to go 4WD
almost as light as i could get it, 18s3p atm, 6355, gear drives and
before the battery i managed to shave it from ~18ish kg to and estimated 16, which is fairly dece ngl
i will find ways to lighten the load moar, and no
no belts for me,
4wd and leightweight are not easy to mesh together cause you’re literally dumping 2x as many of everything on it
i guess relatively speaking tho, your 4wd might be lighter than your other one
If you’re using a thick deck with kinda heavy wood that’s not this huge given you ride 4 motors 4 gear drives I bet (so more weight) plus 54x 21700 cells.
Add enclosure + silicon + hardware nuts and all and the bill rises quick too.
Ok that’s some heavy material you got there all around! So 16kg with all that is no sloush really
Btw you already got like 4kg worth of battery with cables, let’s round it at 4.5kg with esc more cables, heatsink, connectors. Don’t know your motors & drive weight tho.
I guess with some compromises 11-13kg AWD is doable?
meh, for me it’s 4.5kg for batteries, 1kg for both escs, probably a nother .5kg for cables, and uhhhhh, let’s say another .8kg for esc box
so that’s already 6.8kg on the electronics alone
each gear drive is about 1kg, i’m going to guess roughly 1.2kg per motor, so that’s 8.8kg on the drivetrain
not to me tion the hangers which areeeee 850g each
it’s really hard to cut any more weight off without getting rid of the pelican and going for another opition or cutting into the deck afaik
there are some areas but, even on cabling, i’m as little as i can get including the necessary slack so i don’t break anything under stress
11-13kg is almost touching prebuilt levels of weight, and if you wanna i clude a battery, that’s a lot you’re askin for
maybe more possible tho with a street oriented build, i forgot that’s an option, but every last bit of weight will have to count
