Hi,
Managed to change 2 Turnigy F-20A's to brushed, anyone know if it's possible to set or use a low voltage cut-off for lipo batteries?
Thanks

Can you share your changes to make the F20 work?

Thanks Christian

Hi,
I removed a small part of the black rubber backing on the ESC and it exposed 6 programming pins on the circuit board near the red wire.
In order from bottom to top, they are: MOSI/MISO/SCK/GND/VCC/RESET.
The firmware came from: https://launchpad.net/brushed
I used a USB AVR programmer and it flashed the hex file in a few seconds.
After that, connected it up and it's working great
Best Regards,
Paul

What if using the 2 in 1 esc software together with a kk2 to make a Segway?
Should be possible.

Hardware maybe wiper motors from the scrapyard?

Unfortunately I must relay on you programing geniuses. ;-)

Could you please show diagram of how to wire the motor connections to this ESC, I am assuming battery connection will stay the same? Just got a flushing tool rom Hobby King, will try it out as soon as I know the motor connections, hate to fry it.

Thanks
