thats sounds way too much fun we must ban it =P

Not a cheap project. A 18S 60Ah batterypack ain't HK material anymore.
The commercial ESC i could find is the MGM. And those cost an arm, a leg and a kidney.

At the weekend we tested the PWM input and CANBus, both are working fine.

I also think I have found the reason why tracking wasn't working, so will be testing out tonight to see if that is fixed.

New thermal pads arrived which are way better than the last ones and I put the proper waterjet bus bars on, which have much more surface area in contact with the heat sink. So hopefully it lasts a bit longer now when I test tonight.

Have now tested tracking and it works properly now! So just the high current testing to go. The copper bar I ordered hasn't turned up yet so need to wait for that before I can test it properly.

Could send you one of our Revolt 160sh motors with hale and temperature sensors.

That would be great if you are able too? I have enough lipos for an 18s pack so can make sure it all works.

What Kv is it?

[maddox10]

58 KV, and yes, I have 2 of those monsters. 1 for the bike, one backup.

First one is finished and being sent to Rory tomorrow. The heatsink design has changed slightly from this to let you actually plug into the connectors.


The heatsink is the same on both sides to they can be stacked like this

It lacks hoses to carry liquid nitrogen to the superconducting fusion cores.

Hello

looks very interesting, which is the actual size and weight?

[typhoon_driver]

That's a beefy looking esc. Following with interest (having just spent a kidney on a couple LEMs).

Its roughly 800g with no cables. Dimensions are 110x105x30mm

Thank you which price are you actually looking for?

If Rory gives me the green light from his testing this week, they will be on sale for the first batch of preorders on Monday 19th February at a special introduction price of £400 each.

A VESC6 is £300, a Vex Victor BB is about £450 and the closest 250A MGM controller is around £700 and only supports 15s instead of 18s. So I think its a very good price.
