well i use the HS-5945MG for steering, on my 1/8 scale. But with a 10gt might be a overkill.. 945 or 925 for that truck.. throttle a good standard servo will work..
I use the Digital Servos from HiTec. Super torque and great speed gives you the steering response you want. You do not need a really beefy servo for throttle duties...just something quick.
I highly recommend the HiTec HS-5645MG digital high torque servo (160 oz-in for $60).
