i sent in a Mamba monster ESC to Castle creation in kanas, because the switch ripped off the board after a backflip that i landed perfectly, but the suspension was too soft. and it has been more than 9 days, and i called them up and asked if they had gotten it, and they haven't recieved it. weird huh?, or really slow mail, or should i be very concerned or be more patient.
check out this awesome flip at my track at Bayside rc, fremont
