just thought Id check with the DIY community, Ive found out that the purple wire in the middle is the wiper but as the retards who make these Currie thumb throttles use any colour wire they want ,I dont trust that the red is the +. Lets try and figure out which is the positive, red or orange.

never mind
I figured it out
I went and back engineered the old regen pot by putting 3v through it and watching the wiper voltage.
it starts off at 3v and reduces as I pull the lever.
So I put 3v through the Currie pot using red as pos (guess) and orange as neg and the wiper voltage reduced as I pulled the lever.
so Currie throttles are:
red = pos
orange= neg
purple= wiper

so thats sorted, soldered the old plug onto the currie wires and doused the micro switches with hot glue.

Special delivery direct from Motenergy factory in China.
4x revision A stator sets with wider coil slots and 1.8mm wire in place of 1.2mm.


Well things happen quick in the Ripperton Racing Lab, I already have a pair of these RevA stators in one of my existing casings and just went for a test ride this morning in freezing Sydney Winter weather.
A lot more power and resistance to tripping out the controller.
The motor can now handle 90% amperage on takeoff in place of 80% but the controller will still trip out at low speeds under full throttle.
So thats a 33% increase in wire diameter which is pretty irrelevant.
I guess cross sectional area is more important and theres a 78% increase there.
John has also reduced the thickness of the stator from 50 to 48mm which coincidentally is what I had to machine my standard stators down to fit them in with the water cooling jackets, so lots of time saved there.

Have also shipped $5750 off to China for 420 4Ah YGS LiPo cells with custom 25mm tabs. They will be ready to ship on the 4th July so might even have them in the bike in time for the next round of eFXC in Queensland on the 20th July.

I love the continual improvement happening here. Really looking forward to catching up in Queensland. Should be a great race again.

it gets interesting
DHL tracking page tells me my YGS LiPos have been delivered and shoved under the roller door of my lab.
now the gamble is can I get the whole pack stripped and rebuilt in 1 week while not taking any time off from my new job.

well should have known to not get excited, the cells showed up with extra short 9mm crimped tabs when I actually ordered extra long 25mm uncrimped tabs. they are all going back to China and I will have to race QLD on the old pack. good thing I didnt strip it.

That's pretty lousy service! Be careful of sending them back - it will end up costing you a lot more than it should.

Worse comes to worst, you can spot weld copper tabs to them to make them longer, but I'm sure you have better things to do than fold up 800 bits of copper.

I can solder a pack up for you for round three if you like

See you next week Dan!

Bad news... I was looking forward to the battle of the new battery packs.
