Steering servo, how much torque/speed?
I am in the market for a new steering servo for my RC8. It has the original RTR servo that came with it. Its only 41 oz-in and 0.19 sec. It is super weak, and can barely pull the brakes. I upgraded my steering servo to a Savox 1256tg, but I think that would be overkill for a throttle servo. So the question is, how much torque/speed is enough, without being too much. Trying to save my $$ as much as possible.

80oz is too low for buggy.
150oz minimum, speed .15 or faster
150oz minimum, speed .15 or faster

Sounds like a good throttle servo is what you are after if I read your post right,
You can go with a Futaba 3305. It's pretty cheap and has metal gears (should last a while). It's got right at or close to 200 oz. of torque and the speed is I think .15. I know a number of racers that use that servo for both steering and throttle in a buggy.
There are many to choose from at all different price ranges. If you can go with something around 120 oz of torque or better and .15 on speed or faster you should be good for the throttle

I run Hitec 7955's on both channels, straight up lipo.

The throttle part doesnt need much power, true, but the brake part does, and speed is real important here. You need to be able to get on or off the gas or brakes asap. You have a normal bit of lag in radio transmission and then to the servo and if its slower, it adds up to lost time waiting for stuff to happen. In order to be a smooth, consistent driver, you need to be able to act and not react. Going too cheap on servos only hurts you in the long run. brakes need (IMO) at least 150oz and sub .15 times....preferably sub .13 One of the reasons guys go to high volt servo's now days is due to the speed. Not saying you need those, but its a reason they have gained popularity. Speed for the throttle/brake is more important than speed in the steering actually.

I had the same problem with my JR Z9100S

I run stright lipo with savox 1268 on steering and 1267 on throttle.
I did use the 1258 before with nimh both steering and throttle.
it is faster on the paper but not in the track.Witch means that it is to weak for stable steering.
have even used the 1267 on steering and felt the switch to 1268 was faster and more consistent in my hometrack.That are werry hard and bumpy..
