+1 to the servo saver.. it saves your... servo.
Not all High Torgue Metal Gears are created equal.
You do get what your pay for 99% of the time.
You didn't however state what you plan to put this into.
a strong servo for a 1/10 scale carpet car is going to cost alot less then say for a 1/8th Off road Truggy.
Either way, I love the Associated 1015.
