The steering is always sluggish when the truck is sitting still, especially with oversize tires. I don't know what servo is in it now, but look for one with some good torque to make the steering more responsive.

Looked up the specs and it says it only has 49oz of torque, something with 300oz or more would make a huge difference.

savox 0251 is what i ran in my MT's
Way too weak for steering. @ 49oz-in of torque,I wouldn't even use it on my throttle/brakes.

Savox Sc 1256tg has 20kg (277 oz) torque & .15 second speed, it would work alright, run it on a 6.6v LiFe receiver pack for a little more speed.
You want at least 150oz combined if running two servos or 150oz+ with 1 servo. I run a single hitec 985MG on mine (172oz@6V) and it does the job well with revo 3.3 tires.

Check out the hobbyking servo called xq power s4020 its not actually a hobbyking servo but listed as a hobbyking on their website.
I have the savox 1256tg and the xq power s4020 and haven't seen any difference except.
The savox costs twice the price and slightly stronger on 6v
The xq power is water resistant and can run 7.2v nihm and then it just beats savox specs.
Both servos are titanium . Alloy case . 25t spline . Coreless digital . Double ball bearing .
The plastic tabs on the xq might be brittle tho or it could be my fault but I didnt use the rubber inserts and over tightend the screws and snapped a little peice of the tab off one corner but its still gripping on the broken tab.
Theres not tons of information on the servo but a google will pull up many plane threads with people praising the servo for the price you couldnt get a used savox1256 either.
I only read about one or them burning out out of the 30 page thread with multiple buyers buying multiple servos and the burned out one was fitted to the rudder of a 100cc plane lol so it can be forgiven for burning out do that job by itself.
I had a xq power s5040d too in my fg marder and that was also flawless except one design flaw thsy could be a good thing but the spline was over sized like 8.4mm so it was very limited with servo horns but xq did supply it with a plastic double side and an alloy single side horn and again was $35 new for a 1/5 servo 33kg / .21sec water resistant . Alloy case . Titanium gear.
They are definitely worth afew google searches I will only buy these from now the newer servos they are doing are not cheap either so get on while they can still be found cheap.
