Can't say enough about the cirtix stock club esc and 17.5 v3 motor. It's drop in and go for RCGT, and easy to set up even for people as new as myself to b/l stuff. Loving this combo. I can truly say that I beat the living hell out of my car yesterday, esc never got over 90 degrees and motor never even hit 100. Running 4.25 FDR on a Tamiya ta05 v2. Gave nothing on the straight to any cars out there.
