Servo Saver? Which Servo?

[Dazzler]

Two club nights racing and two servo gears later (first gear which is plastic), I'm not convinced that a servo saver is not necessary. The servo I have has the following specs..

DS8417 Digital Ultra Speed MG Servo Specs
Size Category: Standard Type: Digital Torque: 82 oz/in @ 4.8V, 98 oz/in @ 6V Speed: .10 sec/60° @ 4.8V, .08 sec/60° @ 6V Dimensions (WxLxH): 0.75 x 1.54 x 1.36 in Weight: 2.03 oz Bushing Or Bearing: Bearing Bearing: Dual Motor Type: Coreless Hi Torque

I used this in my ZX-5 with no issues - ever! then now in the Cat, i'm stripping the first gear totally effortlesly with a slight clip of the front wheels. Does anyone run a servo saver? If so which one, as space is limited. Also, advise what servo people would recommend.

Cheers.
