here is the spectrum shorty servo spec;
Torque: 208 oz-in (15.0kg-cm) @ 6.0V
Speed: 0.08 sec/60 deg @ 6v (no load)
Aluminum hard anodized output shaft/main gear with steel internal gears
Aluminum case for good heat dissipation
Aluminum mounting tabs

HERE IS THE SAVOX
Speed @ 6.0V: 0.08 sec/60°
Torque @ 6.0V: 166 oz-in / 12 kg-cm

the spectrum is not only smaller but is rated for more torque then the normal savox servos that alot of people
