    Hello!
    Is it normal that Savage eat servos like bread?
    I had driven about 4 litres of nitro, and allready need to change:
    -2x standard throttle servo (sf-10w)
    -standard steering servo (sf-20w)
    -upgraded throttle servo (Savöx 0251MG)

    I use standard radio with glitch buster and 6v hump pack, what can be wrong, or is this just normal?

    All servos has destroyed same way, just suddenly, without any warning no response on commands...
    Any ideas?

    Mine ate a futaba standard servo for throttle brake and a high torque futaba for steering after 4 to 5 gallons that to me is a lot of running they both worked until they got hot throttle brake was worst of the 2 . Just upgraded but haven't run the truck. Buy good servos they work hard mine were glitching bad when hot

    I picked up new throttle servo (Savöx SG-0351) yesterday.
    I only can hope that lasts longer than previous servos.
    Theres still few weeks time to bash before weather goes too bad.

    Hadnt do anything on servo saver, so its on factory settings. But thats not explain why also throttle servos lasts so short time.

    Does your radio have end point adjustments?? if so check that you are not overdriving the servo causing lots of heat buildup.....
    set it so that it opens the carb fully and no more... Same thing with steering , set it so the servo stops just before full lock it will help your servos last longer...
