Y-pedal's two stage RC drive..........

[recumpence]

I should send you a 3220 for grins. If you think adding lipo was a kick............

I'll trade you for an X5 !!

( You owe it to yourself to try one of these hubs at 100v 60+ amps in a 20" rim )

You owe it to yourself to try a motor that can put up with the setup you have.

I agree a huge hubbie cranks. I hate the weight, though.

Hi Y,

The RC version of my dream ebike will come in the form of a KMX trike with multiple motors, a quad 3210 maybe ? would sound freakin great...!

How about 2 of these these (or maybe 1) 15kw RC outrunners Hal and Marko are working on?

Sensored, water cooling (optional), 5.2kg per motor, priced at about $300 each, designed to be connected in multi-motor configurations:

Gee, what post did you see this at? Those wires look tiny compared to the motor, but I guess that's how things go when the motors go huge. It just seems unlikely that it'd carry 15 kW, but maybe it's a "High voltage" type of motor?

This is not the motor we are working on. On the picture is a motor from some factory and we discussed before this motor .. Colossus is 100 percent different motor than this ... This is the first test by Hal : http://endless-sphere.com/forums/viewto ... &start=345

Now that the Chaos is road ready, it's time to lipo the RC bike..

After alot of pondering, i have decided on 20ah.. this is 8 packs in all to fit on the bike... no easy task.

Over the last few days i've been cycling and matching packs, 4 will go on the back of the frame ( disregard the masking tape, just had to make it stay together for a dry fit. )

[Ypedal]

And pack no.2 !

[Ypedal]

Damit.... ... i hate it when the simplest things kick my ass sometimes... i've been sitting with a battery pack in my hands for the last hour pondering how to make a mount inside the triangle to hold that sucker.

the pack on the back will be easy, a bit L bracket with zip ties, velcro and some tape..

But the pack inside the triangle is really giving me a hard time..... any suggestions ?

[recumpence]

LOTS of tape?

Ask a stupid question................

Sorry, Man, I just had to give you a hard time.

You better get that thing going soon. You are going to love it!

Matt

[Ypedal]

I'm totally willing to do that lol... but the damn motor mount is in the way of the tape direction requried..

[Ypedal]

actually....... i could hang it from the top tube with alot of tape............... i wanted to keep the angle of the boxes to match the angle of the downtube and rear trangle..... but at this point i really just want to secure the packs so i can run the bike for a while...

[AussieJester]

LOL @ Matt....yes i would of asumed some duct tape would be a certainty YPedal MaNz

Personally i wouldnt be mounting the packs where you intend too, i would reconfigure the packs so they
are one pack wide and hang one pack each side of the top tube same as Matt.P and Luke have done on their MTBs.
You got 8 packs haven't you? 4 either side of the top tube wouldn't interfere with the pedaling.

Please think about a 24in wheel for the rear too buddy, its not a frock motor you don't need a 20in
No offence intended Ypedal MaN but it ruins what could
be a very nice looking bike IMHO.

KiM

[Ypedal]

lol.. no offence taken ( because.. you are wrong !! ) hmpf..

But on a serious note, this bike is what it is for now, i do have a 24" rim for the Nuvinci but would have to order more spokes, re-lace it, deal with even more gearing problems with limited options on this frame.... nope.. it's staying the way it is at least for this year, i've put too much money into it and far too little ride time ( sound familiar ? ) it needs to run even if it has to be ugly and i'm willing to use Duct Tape... but the black stuff at least.

The ride is very nice with the 20/24 however, upright seat position with both feet flat on the ground with ass on the seat, exactly the way i like it.

One way or another.. this bike is getting driven with 48v 20ah LiPo ..Tomorrow !

LoL...yes we know you frock fan bois think the 26-24 front and 20in rear on a MTB is the look trust me, it ain't YPedal MaN haha

On a serious note yes i know exactly what you mean by lotsa money and limited action ...also, have you seen the digitial camo
duct tape? it looks quite snazzy. Your bike would be near invisible in an urban environment if you covered it with this
talk about stealth hehe. You could also make yourself a Duct Tape digital camo tuxedo! to complete the look

KiM

p.s either way HURRY THE FARK UP we want to see video of this sucker on Lipo and your reaction after it

p.s.s your holidays are comming to an end too ain't they mate? back to work soon is it? joy joy

[Ypedal]

Week 1 is over....

2 more weeks to go tho !

OH!! i thought it was only 2 weeks ripper...a drunzored YPedal MaN for another two weeks woohooo hehe

This will give you ample time to get this puppy performing.. :: cough :: place an order ::cough:: for spokes :: cough ::

Alternatively buddy...have you thought about upping the stakes to moped rims and/or motorcycle tires on 20in rims, this is my favourite
look of all on a mtb looks so super motard like



You did say many pages back it was going to be 20s front and back...i gather pedal strike put you off? 160-165mm cranks
and the larger motorcycle tires/rim combo would give you a heap of clearance!

KiM

[deecanio]

ahhh colby's bike, damn good for the sum of its parts!!
im with Kim here Y, never been a fan of the penny farthing look, sure you cant sneak a 24 in there?
Do you really need 20ah in one hit? i'd slim those packs down and get em in the frame (4) altho i definately know the pain of all change!!!
ride it as is for a bit, all changes can be done in the winter, be here soon enough thats for sure.
Looking forward to the vid/write up of the lipo, sure is a lot of power in them suckers.

[Ypedal]

Nice Rig !!!... i like those 20's !

update : I have both positive P cables done, will post pictures in a bit.. working on the negative wires now..

Both packs are now mounted to the bike, and yes, it involves tape.... .. but she'll run like this for now !

12 more anderons and one more ballance lead pigtail......... i should be able to run !

[deecanio]

go Y,

not at all jealous of your summer vacation as always, video man, video!!!


D

[Ypedal]

Video.. absolutely.... will fire one up ASAP.

Regarding the Parallel cables...

Found a strip of copper in my stash.. cut a 5mm band, sanded it up nice and clean.. stripped back all the cables ( 4 x 10awg leads, one for each pack, and 2 x for the output side with PP45's )

[Ypedal]

Ganged up all the cables and banded them together with the copper strip.

[Ypedal]

With my Hakko 936 station set to MAX, fill with solder, flip, solder some more, repeat..

This Turnigy silicone wire is awsome !!!.. anything else would have melted into the solder joint making a mess of things but this silicone jacket remains in place while getting HOT>...

I tried with a butane torch but the heat canot be directed well enough and it was impossible..

2 down.. 2 to go.

[Ypedal]

There... after a full afternoon of soldering and cutting and glue etc... all i have left to do is crimp a few more andersons and Voila !

[johnrobholmes]

Whew, gives me a headache just thinking about that much soldering!

I say hang the pack from the top tube inside the frame, with a brace on the seatpost tube. I just made a wood box for one of my bikes that holds 4 packs in a brick, with silicon cushions for the tubes. Working on the cinches still.

[Ypedal]

How big of a voltage difference can you have between cells when you hook packs up in P ?

I have 4.15v to 4.18v cells.. last thing i want is to plug the ballance leads up and see the silicone start to melt....

[johnrobholmes]

I haven't had a problem with anything under .07v difference. Around .8v is when I work harder to balance the pack, just cause it is almost .1v difference
