Servo question

[fxdwg2002]

I'm looking at getting a new Spektrum Dx3 that comes with 2 receivers and a Z270 Standard Race Servo, Z590 Hi-Torque Race Servo. Is anyone running these? Would these be an upgrade to the stock Savy servo's?

They are good servos. I use the 590 on the throttle and I have a ultra high torque on the steering. I use the 270 on the throttle of my on road car.
The radio is great overall. No glitching and built in failsafe.
The 590 does have metal gears where the stock sf-2 servo is plastic.
Hope this helps
