hacker,
Not sure if you have read the instructions for the SXX SS V2, but Mode 2 (Torque/feel) and Mode 3 (Boost) are fully adjustable.
I used this ESc connected to a X-12 and X-11 21.5 LRP motor last weekend to win the AARCMCC ACT Titles. Way easier to tune than the others. i could concentrate on car setup and driving instead of chasing ESC setup all weekend.
I had no cogging issues and temps were 67C after six minute races, with no car fade. I used the X-11 for most of the weekend, as I believe it is a better motor than the X-12 and less resistant to fading. I also used FW 4.2 which is what it comes with and have just had Reto E-mail 4.4. I ran a 50mm rollout and approx 4 FDR on a MI4 LP, open settings.
Just my two pennies worth.
Calvin.
