Have you noticed any difference between the 2 frequencies?

Was too cold last nite to run both 8 and 16khz to record a difference in efficiency. I will warm up my battery pack before I run the frequency difference test for max output.

I should try those packs Mike sells and see how low I can pull those with this ESC.

Little video of the 1.5T working:

It takes a little bit of power to get it moving, but the 200A ESC doesn't seem to mind it.

Luciano,

Can you post or PM me with the 6s ESC set up procedure? I'm just now getting around to some holiday projects and don't seem to have any reference documents in the package.

how're you going to keep that motor cool? Even just for speed runs I'd imagine it getting red hot...
