To keep this up to date, I bought an RS Pro 2 days ago (waiting for it to get here) and I put my Nosram ESC up for sale.
As for the motor, I think I'll stick to my initial plan and get a 4-pole motor.
Sorry rootar, thank's for all the effort you put in here, but even if there are 4 million 8.5T Redlines working flawlessly in SC10s all arround the world. I will be the one having issues.
So at the moment I lean towards a
Leopard LBP3650-B/4D.
Still an alternative is the
IN-RACING Afterburner 3650 - 3300 RD 3.
