nitroholic, the one you linked is still only 83oz torque, and 'kryptonite' gears ? i dont know whats that but its no metal gears !
get the 645mg, its got metal gears, ball bearings and has 133oz of torque.
for the steering always use metal gear servos if possible.
How much torque does a 15kg/cm havein oz/inches?
I bought some of these for a heli, but they're getting used for steering:
