I am pretty sure that MetalMan has been using his Phoenix 110 ESC successfully in his Savage. You have to sue mechanical brakes in order for it to work.
OK i want a back up controler in case where my MGM 16018 die, and i can't decide between the Quark 125, Barracuda 125 and the Phoenix 110.
And i ever use a mechanic brake on my revo so it's not a problem for me.
