Servo for an XO-1
 

I have an XO-1 and it has a stock Traxxas 2075 servo for the steering. I want to upgrade due to I have had 2075s go out way to many times on me. This is the biggest and heaviest car I have owned and would really like some ideas for servos. I have never used Savox before but hear that they are god but can be glitchy. Heck while looking on eBay I found a seller selling a Savox with a glitch buster included. Now if I were to go Savox and needed a glitch buster, where do they plug in at? Do they just plug into any open channel on the RX? So anyone have any ideas as a far a a decent servo for this thing? Any help would be appreciated.
