mechanical? not sure how they'd freeze otherwise...
in other news, it seems i've got a few vids on youtube by now!:

Yup. The camera is to low up front. Maybe would be better if it was at the height of the stem.
On my KMX, I have a flashlight mount bolted onto the boom... and it NEVER gets dirty 
the only wheel in line with it is the rear, and that is covered with the rack and such but, during the summer months I think I'll miss the feel of an upright. Until I stop for lunch on a beautiful hilltop and enjoy the view from my convenient, reclined pose ups and downs!

going to swap out the rear wheels again this weekend. can't wait to get the MC wheel back on. the studded tire was okay in the icy junk, but all week, the following things have bummed me out:
- motor overheats so fast w/o vented sidecovers i can't get halfway home w/o it getting heat saturated (i could drill 'em out, but hadn't did cause of the salt...); good thing i'd fixed the temp sensor, otherwise i would have surely cooked the halls or worse...
- skinny marathon winter tire pumped up to 40psi but still feels flat (and it wobbles but that's another story)...
- so terrified i'm gonna get a flat i'm afraid to jump curbs w/o putting weight way forward...
- traction/turning on pavement is so inferior, haven't even bother to record the commute it's so boring..
the only thing that i've enjoyed is pedaling at high speeds w/ the 11T cog. if i could put that on the h40 MC wheel, i'd be set. i'm sold on the h40, with the extra tug and the heat management, it's the best i've had.
i'm ready for spring!
next year, can someone please remind/convince me to drill studs into my MC tire?

ready for spring post II:
whoops:
yay:
in other news, went skiing yesterday. charlie took his skiis off in the middle of the busy line and i had to haul him out of the traffic to get 'em back on. while riding the chairlift up, i wanted to take a clip a vid with the gopro but it wasn't in my inner pocket anymore. i'd had the long extension handle and it must have fallen out. hurried down the hill, no sign of it at the lift, and the operators hadn't heard of one turned in... it was a dark moment, but my daughter said she'd give me luck and a sure enough, some kind soul had turned it in to guest services! phew!!!

crown huh? the one w/ the weird spokes? (just searched and found it) looks pretty damn fat. cromo fat. or do they fit 135mm dropouts? hmm.. no worries. i'm always behind the curve...Hyena said:the crown is the new hotness
batt life is horrendous. i always wondered if you got extra batts for your yosemite trip when you got all that awesome footage. i was pretty shocked when i first started using it, and pretty pissed when the batt ran out. i got an extra pair of batts w/ a charger and always have them handy...Hyena said:
nice commute this am. could practically taste the spring. monster wheel traction is such a relief for serious riding...
not really excited about filming anything tho. oh well, maybe something will inspire me someday..
been thinking a lot about welding up a go kart for the kids. that could be fun.

I finally sat down and went thru your entire tread-all 90+ pages and videos. Quite a read-it took several nights. Very inspiring.
I kept waiting for you to break some axles like many others with Hs have done. Yet you endure-congrats!
What do you attribute that to-excellent torque arms?

hey kent, i'm impressed. it took endurance on your part! certainly has been a journey... any favorite vids? (besides my highlights, my recent fav is this one):
[youtube]yIrutg3TT5Y[/youtube]
to break axles one needs monster torque i believe, and overheating has always been an issue, so i used my 18 fet infineon maxed to 45A, and the adaptto to 60A. either that, or:
- others have carved out too much axle to accommodate beefed up phase wires, my recent hs3540 had stock phase wires
- the axles have been stressed due to misalignment between dropouts or pinched too hard or banged on?
- some just got bad axles that had imperfections that doomed them?
i don't know, but i know the axles would have been much more stressed if i had it installed in a hard tail w/ small tires and took a big drop, compared to my giant balloon tires and 8" of rear suspension..
all speculation on my part.
in other news, i started to make a new rear fender to mount closer to the tire. i put the strip in the oven first but by the time i got it out to form, it had cooled too much, so i first clamped it between some studs and then ran a torch over the flap that stuck out and then clamped it down:
worked great, but in retrospect, a 90 degree angle is a bit severe for a fender!:
and yesterday's inbound commute seemed slower than normal, so i hung the rear from the ceiling with a rope:
and tested all the phase combos by running autodetect on each one just to see if any one was faster. (i no longer know the colors, so just marked the connectors on the controller and motor side w/ 1, 2 & 3.) the pack had only 30% left, so top speeds were lower than before. no one combo was faster. one combo had a max of 52/54mph, but when i went back to it, it too only had a max of 52mph.
i didn't check WOT when batt fully charged, but from earlier tests, it should be around 60mph unloaded.
and so how in the world my old hs3540 got 80mph is still a (sad) mystery.
one possible difference is that i extended the phase wires on my h40 motor in order that they'd reach a controller located on the forks (see the excess drooping down?). but that doesn't explain how when i run autodetect on old hs3540 i can only configure it w/ a max speed of 60mph...
i may just want to try out the maxE, but i really need to sell some stuff first, like the hs3540 motor, and some old 18fet 100V 45A controllers, and then the miniE once a maxE arrives. PM me if interested, otherwise i'll just put 'em in the for sale when i'm ready...

Did you try to play with ovs setting in advanced menu? I dont think upgrading to a max will solve your problem. Did you adjust the speed using a gps? How is your speed ratio set(circumference/pole count)?
GCinDC

nope. had same config as andrey suggested before. didn't change it. have you had different results? i need to check out your thread. what voltage are you at?Allex said:
well it would if i upped the voltage, and amps... handles up to 15kw? the miniE is limited to 3kw continuous, 6kw max. and i was thinking i'd swap out my 20s2p (10x4s) pack w/ my 6s batts to go 24s2p, but the new bms may require 4s subpacks (in which case i could just add 4s or 8s to up the voltage/speed)...
yeah, i checked it once. i'm w/in 1-2mph give or take w/ MC wheel. didn't bother to change it for 26" studded wheel. can't recal speed ratio, but vaguely recall something like .84.
in other news, i started using a timeri bought for charging:
i plug it into wall in the garage, insert an extension cord w/ multiprong that has my battery warmer and charger on it. and it's set to turn on at 5AM and both charge and warm the pack, so by 7AM when i hop on to commute, the pack is all warm and balanced.
i used to always charge up in the evening and then turn it off, but this is much better because the pack doesn't have to sit long while fully charged.
in fact, doing this, i could probably safely increase the charger voltage from 4.15V/cell to 4.2V/cell and that might help w/ speed in the first mile or so...

i recently ordered the 28s bms from Andrey which is available now, but it hasnt shipped yet. i also got a couple of mini-es and a charge choke to play with.
ill post pics etc. when the order arrives.
i diddnt know about the 4s subpacks for the bms.....so each board handles 4s at a time?
6kw is already a stinking heap of power in my book. the most iv ever used on my max-e is 7kw, but that would have been going up some crazy steep hill at full git.
i reckon the mini-e is probably plenty adequate for an e-bike unless you want to go serious hooning.thats where it all falls apart ofcourse...
what are you feelings about the mini-e power output now?

mine is older version. i have 5 boards (one master, and 4 others, with two 4s batts attached to each via JST-XH connectors). i believe the new BMS is one board. not sure what it supports. i'd find out if i were you! or me!ridethelightning said:
well all things are relative, and power is corrupting, and another factor may be that my zippies have several hundred cycles now and do sag some. i've been meaning to swap them out with the ones i got that were damaged from poor packaging, but seem ok. (sorry dnum, but i do have a box of other stuff to send you.)
there's power and there's speed. 50mph felt good on the high end. i really don't need more than that (for now), but do miss not having it. would be nice to have flexibility to go higher.
as for torque power, i don't even want to talk about it. i'm over hub motors for trails... really hoping for a middrive solution someday! :wink: in other news, just saw this and don't think i've ever seen something so informative and so graphically intense:

no problem, the zippies would not help me much since i need to get some more of the 8Ah turnigy nanotech to go with the current eight 6S packs i have to make it to ten 6S packs so i can go to 20S 3P like you. but 200 cycles doesn't sound right. gaston said he was already up to 700 cycles.
i am getting nervous about sending batteries through the mail now too since they always seem to look at me real close when they ask me that at the counter in the post office.
like i have 'lithium battery criminal' printed on my forehead. guilt is bad when you wanna be straight. hehe.
but i wondered how you are gonna charge to 28S. i don't think either of those two chargers can be pushed that high. you gonna be flying. now you gonna get speeding tickets.
his controller has to be super strong to withstand the 118V too.
i think andrei should be proud of what he has done. plus he got you away from the balancing chargers which i feel was the cause of the fire.
towing the sled is a fav of mine too.

Yeah, when you change OVS from zero to 2 or 4 things starts to happen, the wheel starts to spin crazy fast.
The recommended value is somewhere between 0-4 I think
I haven't drived with the controller yet, so really no experience point on my side

i checked before my commute this morning and my OVS was set to 2. i upped it to 4, lifted the wheel and @WOT, the wheel spun at 60mph.Allex said:
i put the wheel down, upped it to 5, and @WOT, 71mph.
and on my commute, i had my speed back, hitting 50mph at one point when i dared look. woohoo! i'm back!
so many mixed emotions. JOY. embarrassment. thinking back, i figured andrey had told me to set it to 5, and couldn't imagine how it changed, but just now checked the old email and he had recommended setting it to 2... just checked the manual and it says:
Code:
OVS timing: 0-7 value allows you to run a bit faster on the same voltageyep. love how they're using regen. didn't understand how they're using the heat tho! very interesting...sardini said:
me too. amazing that HK keeps shipping them priority mail from us whorehouse. :lol:dnmun said:
incredible what he's done. i was wrong about 118V tho i think. (never trust what i say!) just checked and from here (written in 2012):dnmun said:
so glad to be done w/ balance chargers for commuting! definitely a suspect for the fire, combined with my poor practice (leaving it on all night unattended, with no timeout...), but a punctured pack and/or shitty wiring/connections could have been it too.

Careful with OVS tho, I believe that if you change the value to the greater, the efficiency goes down. Better talk to Andrey about best setting for your motor.
I run 72V on 5403 when OVS=2 the speed is 60MPH
OVS=3 makes it go 112mph

slightly OT, but thinking about something fun for the kids this summer...
this might be a bit big tho seems like a giveaway at $100. what do you guys think about replacing the ICE (and ghetto gas tank, lol) with a hub motor as a middrive type?
