Not a patch on his first vid, all the car stunts are old now so look s to me like the producers felt the need to as special effects to keep it a little "fresh"
Good driving no less, Ken Block is good until he races against the worlds best rally drivers, he struggles to make top 10 in World Rally, I would like to see someone like Sebastian Loebe cut up on a movie set or a vacant airport.

I think Loeb is too busy winning World Championships to bother making Youtube videos. Three Race of Champions titles says it all really. Undoubtedly, the most talented driver of his generation and one of the few people in the world that steers cars with their feet as opposed to their hands.
Edit: Race Of Champions.

I especially like the parts where you pass the other bikers like they're standing still, the seagulls, and the road kill.

Greg, long story with the name, had it forever since being online. Kinda started back in my uni days when I was the first guy to get a CD burner and I'd use to scavenge everyones music (and from early online mp3 sharing) and make my own compilation CDs, which were 'released' to friends under the Hyena Records label. Totally redundant these days of course but in the mid-late 90s it was a bit of a novelty. The fake label continued on for years "sponsoring" a car I hotted up as the Hyena Records Racing Team and other unofficial sorts of events until a few years back one of my friends was googling for an old Hyena Records website I made up and found someone had actually started a legit company under that name. So Hyena Industries was born, a somewhat more future proofed name for any of my new and continuing endevours
Back to ebike related news, I'm feeling good today a few days after the last cycle of chemo so decided to take the new HS35 rig out for a spin. The current limit is set to 100a on 18S and it's a bit of beast Trying to calibrate the CA off my wattsup meter ended glacing down a bit of long and next thing I knew I was right in the gutter. Still being a bit wonky I didn't have enough time to counter balance but braked as hard as I count before hitting the gutter and tumbling off. I landed well on the grass with only a slight shoulder roll and no injuries other than the slightest rub of skin on my jeans. The bike too was undamaged luckily with only the pedal and axle on that side of the bike hitting the ground and apparently nothing else.
Dusting myself off I decided the CA calibration was good enough for now (accurate up to 50a with the WUM, out by 10-15a at 100a) so went for a longer slower ride up to the local shops. The bike went well in 50% mode and was quite economical but I have it a hiding coming home to give it a proper run. The stock phase wires got nice and toasty, up to 55 degrees. I dont have an internal temp sensor in this motor but I reckon it was getting near to cooked - the motor side covers and magnet ring got 80 degrees C with no air cooling holes so it was definitely much hotter inside. I will admit, I was riding it harder than I normally do, trying to see just how hot it'd get in stock form and also trying to drain my new 10ah pack as quickly as possible to test a new soft LVC. This involved alot of riding up steep hills pulling 60-80 amps continuously for a minute or so each time (normally I'd only sustain those sort of currents in ~ 10 second bursts. 500m away from home and 9.5ah in it started to get a hall like stutter so I pedalled the rest of the way. It seemed to have gone away by the time I got back to my driveway but now 10 minutes later it's back. Dunno if its halls, the wiring or a fet (only a 12 fet controller so it's pushed to the limit running 100a sustained), kinda feels like it could be any of the above. I don't know which I'm looking forward to replacing least!
Hopefully more good days like this ahead and less driving the porcelin bus

Looks like it's the wiring chewed through again. F*CK these bloody Hx motors!!! 
Bad photo from my phone but I can see the white insulation has rubbed through to to reveal the conductors of the hall and or/phase wires. I just tested it with another motor and it's fine so it's not the controller.
I think I'll have to dremel the axle groove a bit deeper and try and fit some sort of tight fitting metal sleave as close to the axle exit as possible to hold the wires in tight. Or try to epoxy them in or something ? Good excuse to drill it and fit an internal temp sensor while it's open, but I'm not going to run further wiring back outside the axle, there just isn't room. I've just ordered a 130 oC NC thermostat which I'm going to wire to one of the hall wires. When the windings get close to critical temp it'll go open and give me a hall like failure to tell me to back off, but will reset itself once I take it easy for a minute and the temp drops a few degrees. Potentially dangerous I suppose if it happened in the middle of an intersection or something but no worse than any other failure that'd happen shortly after from overheating.
I'll drill it while I'm in there so it will probably never get to that anyway.
In unrelated news I've decided to spend my birthday money this year on getting a cheap welder. Nothing too flash given how much use it'll actually get but I'm hoping to use my good days off from chemo (or atleast the hours in the day when I feel good) to learn how to weld and hopefully turn out a custom frame I've wanted to do for a while. I really wanna do a RC build at some stage but think I'll start of making it hub friendly and go from there.
First project will be making some bike stands and jigs to practise my skills, then move onto a little kick scooter I've got here that needs modding, and then onto a proper frame. Don't be expecting Aussie Jester type build quality though, I haven't got THAT much time :lol:

Holy hell man Im nervous running my 12fet/ht at 50 for more than a few seconds! ive got the ca limiting it to 25A, or at-least what it 'sees' as 25, I dont think its quite calibrated yet. And i reallly dont want to break anything untill ive sorted some kind of backup... wadda ya powering it with, excess radiation :wink: ?Hyena said:

Thanks beast, the only problem now is I'm going to have to put my thinking cap on to come up with some new and better footage for the extended version!
I always said when I bought these motors I would have an extra for R&D to see just what they could take
A HT should run 50 amps all day long - don't worry about that. Get you CA calibrated though so you know exactly what you're looking at. I just threw my spare HT motor back on the bike to check it wasn't the fets and it barely hit 80 amps when gunning it like I was on the HS. Torque off the line is snappier but only up to around 20km/hr or so then it's the same as the HS. I think the HS with 18 fet controller will be my combo of choice for the extra top end for an all round bike, otherwise the HT would be ample for just offroading. When I hit the trails quickly this morning Ikept it in 40% speed mode most of the time, only flicking it across into 100% for short bursts. I don't know if it's because I haven't ridden in a while or I was taking it a bit easy down the hills and then nailing it along the flats and up hills but the acceleration was fantastic.
It is pushing my luck with this motor and that level of current though so I should back it off. 60-80 amps will still give great performance and should be kinder on the whole system.
Thanks for the frame building link, I'll have a read of that later. I reckon I've got alot of late night googling and forum browsing ahead before I get down to work. First thing is to buy the welder, then scrounge up some scrap metal to play with. I just threw out an old steel frame bike a few months back too. Oh well, another will come up on a junk pile, just gotta beat the scavengers. I dunno what they do with them all but I always see them riding around with trucks piled full of bikes.
Yeah by that's how I roll :lol:sn0wchyld said:100A

Hey man, bad luck about the breaking in issues with your new machine.
Glad nothing went wrong while I was riding it, although I didn't crank it up all the way. It looks like there were plenty of big hills around your area to test it on too.
The welder project sounds like fun, but I'm not sure how that fits in with the "clearing out the garage" part. Of course you'll need a pile of clams, hammers, and other tools and a rack on the wall loaded up with steel tubing stock as well to go with that...

funny you should say that mate, ive bought myself a cheapo gassless mig too, with the same intention. Turns out I now have access to the uni's tig welder, witch Ill probably use when I do start a frame build since It yeilds better welds and lets me work with aluminium too!
good to hear your confident about the ht's power handling... Im just being cautious in the early days since I want to get some serious miles out of it before I kill it completely. riding it 'hard' today with the ca limiting it to 25a and it barely got warm, though it was a cold day today. after the lipo's been cycled a few times ill turn it up though
do you think the phase wires'd handle 50A thoh? Just plainning out how soon ill need to upgrade 'em.

50 amps through the stock phase wires is fine, I'll post some pictures later but I almost managed to smoke the windings on mine by feeding it 100 amps irresponsibly. So neither the stock phase wires or even the 45a andersons were a limitation. It seems you can cook a stock sealed motor before the phase wires will let go.
In other news, I just pulled the trigger on my new welder. It's far from top of the line but I decided to go a step up from the real cheapies. This one is a 195a gas/gasless mig. Probably get delivered Monday. Hopefully it's good enough for what I want to do and if not it's another piece of junk to clutter up the workshop
Time to get planning on what sort of custom frame I'm going to make!
Maybe something like this, hey AJ :lol:

^^ might be a bit advanced for your first effort perhaps no suspension
and total pink duco would be more realistic Jay
Get yourself a frame jig happening, good practise for frame building and they
are invaluable if you want a frame that won't 'crab walk' down the road like
some efforts i have seen done without a jig...

I'm thinking a hardtail is probably a good first choice too, as much as I'd like to jump straight into a full suspension build I think I could do without the added headache of getting all the suspension linkages properly sorted. And even then I'd probably go for a basic dirt / pit bike type set up.

Jay,
If ya haven't already come across it RattleCAD http://sourceforge.net/projects/rattlecad/ an open source bicycle CAD program might be of interest. Helps with geometry. Only comes with templates for 'traditional' style road or MTB frames though with a bit of creativity can produce some good drawings. The tubing mitre templates are helpful as well but I will admit to getting a decent tube notcher pretty quickly.
Cheers,
Glenn
