you dont necessarily have to buy a digital servo. digitals do offer better frame rate resolution and better centering. if you have the money they are nice.

picking out a servo depends on the application. large offroad vehicles require a strong servo with plenty of torque to steer the wheels. onroad doesnt require as much torque but its nice to have and gives greater performance. a higher speed servo is always desired, and usually when you buy a digital servo or a high performance analog it'll be plenty fast.

what car do you have?

both are great cars. i personally like the balance of belt driven cars, but you cant deny that its much easier to go with shaft drive if you run on a dirty parking lot.

if you are planning on a touring car, get some futaba S9550. they have over 80 oz of torque with a 6v receiver pack and plenty fast. plus they are low profile so on a setup like a V One RR Evo it'll be tucked away more.

Look for a Digital steering servo that has at least 80 oz of torque and a speed of 0.14 or faster. Look for a throttle servo that as at least 80 (the more the marrier here) oz torque and a speed between 0.17 to 0.12 or so. You do not want a servo that is too fast on the throttle, since a very rapid opening of carb (as with a 0.08 type servo) will cause turbulence that can cause the engine to hesitate as it is trying to rev up and acctually slow the acceleration down. I suggest you get a analog throttle servo since they last longer on throttle duty than digital ones, plus, you can save some $$$ here without loosing performance on the track. Plus, digitals drain your Rx battery faster than similar performance analog.

guys I have a problem with my steering servo. its a KO 2173 on mtx3. when I make a left turn "noise" is made by that servo and its still there even if I release it using my controller. And I dont hear any "noise" when I make a right turn.

If the sound is a buzzing sound then just check your EPA (End Point), might be that your EPA is more than necessary for the LEFT, means it has reached the maximum throw and it is still trying to push further. Cut your EPA.

I am not a fan of digital servos. Their biggest problem is current draw. Although maybe less of a problem with the latest receiver pack capacities, but you will have a lot more run time using analog servos.

Also many digitals seem not to like the hich vibration environment of nitro cars.

I use the Sanwa/Airtronics servos in the non digital form.

Don't you think that faster, more accurate and more holding power of the digital servos would make a difference on the steering while not having a lot of benefit on throttle / brake servo? Have you tried digital on the steering before?

I would think that having digital servo for steering and analog on throttle / brake would be the best compromise on performance and current draw.

And yes, using digital servos would be the only thing that would take advantage of the lastest High Response Systems mode technology on certain manufacturer's transmitters for what it's worth...
