Now where are my royalties? (J/K):005:

Electric motor was invented long time ago...
By Nikola Tesla...

And your idea wasn't quite the same. Yours was to run 2 motors from 1 ESC (I published tons of info how to acomplish that and why not for brushed/BL sensored/BL sensoreless motors (On Russian web)), mine how to make good sensoreless motor run in sensored configuration, where torque comes first.

It was interesting to match motor phases; they were not in the same order as feigao or novak. This is Ok for sensoreless ESC but doesn’t match sensors map in sensored configuration. So if you connect two motor together and one spins but another only moves shaft back and forth then you need to change phases firing order, by swapping wires. Do not be confused with swapping motor wires to change motor direction, similar but not the same.

How does the hacker do on it.

Works better then I was expecting. Lost some torque but still has no problems with lifting front wheels at any speed and any gear. 8-10 minutes and 12 3800 cells are done, ESC temp - cold, Motor - 65C. (It was 7C outside as well :)).

72 spur 18 pinions (66 spur and hacker C50 do not work with emaxx tranny with 18 and below teeth pinions). Performance matches hackerbrushless website numbers plus has nice smooth low-end torque. But not as good crawler as 7XL :)

Feigao sensored?!? Are these readily available, or special order? Make sure to let us know how it does!

What is it Artur?

it has got a 1/8th shaft?

But it sure looks like a feigao..

[coolhandcountry]

Sweet. Have you got to try this one out? I am curious to how it does.

[GriffinRU]

It is Feigao 6XL with 5mm and flat spot from factory.
Yes, it was custom order, but they can be ordered through US distributors as well.
Right now I have some problems with sensors, but I am trying to resolve it.

Does that work with the HV-Maxx controller? I would have thought a 6XL would be a bit too much for an HV-Maxx controller..

Yes, it should be alright. We discussed current ratings earlier in the thread. And I am not planning to draw more then 60A from 12cells (currently, while testing, I can see that ESC can handle 80-130A with no problems). But later, upon success, I will do something with HV ESC to increase cell count :) And hopefully we will have a nice selection of sensored motors to substitute HV-Maxx system motor.

If you can get all of this work together, then I won't hesitate to run sensored! Good luck figuring out the sensor issue.
