Couple of shots from Wacky (Wakefield)

Kelly finally found the fault with the 2 600A controllers.
apparently it was the high speed firmware.
Only when they went back to retest them on a larger motor at higher load did they actually get the controller to cut out.
They reflashed the micros with standard firmware and they perform ok.
Will have them back next week.
Can use both of them on the Quad stack.....180kW ?

Good to hear the big controller's are sorted!

180 kW sounds perfect maybe upgrade the liquid cooling flow rate and rad size a little while you're at it though

A 7.5 kWh pack of these inexpensive cells would be capable of 300 kW continuous so no problems there!

If you could keep a bike pegged on 180 kW, you'd drain a 7.5 kWh pack in 2.5 minutes!

the 600's came back on Tuesday and had one in the bike the same afternoon.
It performs ok and doesnt cut out but has rough regen especially at low speed.
Anyway I made a new dash board and installed a blue led in between the 2 kelly led's which lights up when the cooling system is running so now i dont forget to turn it on.

Heres one for the X Files people

My motor is producing air bubbles in the cooling system.
when left sitting for 2 or 3 days the coolant overflows out the reservoir.
When I run the pump I can see bubbles come out of the motor coolant hoses
till they are all purged out through the reservoir. Theres no water leaks.
Theres some green rust inhibitor in there.
wierd stuff

Anyway off to Eastern Creek this Friday to do the practice sessions for this weekends
round of Aus Superbikes and they have assured me that if my bike is fast enough to
keep up with the Supermotards they will make provisions to include electric bikes in
the "bitsa" class next year so I will be racing with the 125cc 400cc and SuperMotards.
Have the 144v controller in but havnt made the new 165v pack yet.
have made a better design of end frame that is less damaging to the cells and
will be making that in Nov and Dec. 40s10p.

Set another stator on fire today at Eastern Creek and this time it didnt have anything to do with leaving the cooling system switched off. Was the sprocket side again so its looking like a stator quality issue or my rotor to stator air gaps arent equal.
The bike is riding well though and was able to push it hard through turns and hold higher cornering speed but still only 155kmh down the straight on 132v.

Now planing on designing an outrunner motor so I can make and wind my own stators and use simple cheaper rectangle magnets.

got the LiPos up to 40 degrees C as the motor blew. hottest yet but thanks to ventilated design am able to keep temps down and avoid meltdowns.

in the pits

Good to see the bike continuing to get out.

Were you able to keep up with the other bikes in those classes or did the stator meltdown to early on to tell?

Would like'd to have made it down, hopefully next time!

[RIPPERTON]

I overtook one Tard but he was real slow and just floundering. I know I can make a bike fast enough to keep up with them, means I would have to take another 15 seconds off my EC time so under 1m50s.
Ended up getting a Trophy for win of overall TTXGP class (was the only bike in that class). Heres the Trophy shelf.



Heres one more good shot I scrounged up of all 3 of us at the first Eastern Creek round

Wouldnt turning the LED on when the pump is not running draw more attention?

much of a muchness
once I learn to use the light on method it should serve its purpose.

The light off method would need a normally closed relay and that would add weight to the bike, reducing cornering speed.............
