550 ? johnson motors on ebay

[FESTER2004]

hello i saw on ebay these johnson's 550 motors on ebay.they claim they are better than the titan motor.i want to put a titan 550 motor in my extreme blackfoot.also what was gonna do was to get a y battery plug adapter so i can run 2 7.2 battery packs,i was gonna zip tie the second battery pack under neath the one that sits in the chassis.also can the stock tamiya esc handle the titan 550 motor???

anybody ever use the johnson 550 motors?????
