To revive this topic again.
I'm going to buy the LRP Sphere Competition and 4 star motor. This is mainly for my 1/12th car (legal for nationals now

).
I also want to use it in my 2WD B4. Should I just set the punch to the lowest low grip setting? I'm only really going to run at Bury Metro, Southport & Batley in regionals, club days.
Also has anyone tried the Sphere Comp with a brushed motor? Wondered what it would be like with a 19t in my 1/12th to save swapping ESC's.
