The Savox SC-1252MG is a very good servo and it work perfectly without a gitch buster in my VTA car and 17.5 Touring. Speed rating is .07 sec @ 6 volts and it is a low profile servo.

Like a lot of people said above, For me its been Futaba very reliable and predictable, saying that I just bought the low profile Reedy servo to try out. But the argument from going to something .06 USGT to .10 VTA may affect driving, guess Im going to find out.

let me ask...what speed/tq is recommended for a TC chassis then? because i'm seeing some with speeds at .13. is that excessive?

I've always looked for something around .10 seconds or faster and 125 in-oz or greater.

Why do some servos lock fairly solid when power off, yet others move fairly free?

That has to do with the gear ratio between the motor and the servo output. The higher the gear ratio, the harder it is to back drive the servo. From an engineering standpoint, there is a inertia of the motor armature, but the effective inertia at the output shaft is the motor inertia times the gear ratio squared.

And how does this relate to servo performance? I guess not much, because the 3 servo makers I'm using all perform very similar in cars, but not when the power is off.
