Default Losi 8ight-t 2.0 Servo help

I used google alot, but I am trying to find out basic information, not what is the best servo, but what specs I should be looking for.

The throttle/brake servo
-what speed and torque would be the minimum and recommended amount

The steering servo
-what speed and torque would be the minimum and recommended amount

So far from reading online it would seem that the steering should be high torque and the throttle should be more a speed servo, please note that I could be very wrong.
right now I am looking at the HS-7945TH that seems to fit the bill for both the steering and the throttle/brake.

If you're running 7.4v then yes it would be great for both positions. But if you're only running 6v I personally would look for a little more grunt for the steering.

Lots of people say 140.0 oz-in. torque on a buggy's steering min. but, on these higher bite clay tracks I like something stronger and I'd be inclined to put something even stronger on a truggy.

For example- my buggy steering servo
Savox SB2271-SG
Speed:@ 7.4V: .06 sec/60
Torque:@ 7.4V: 277.0 oz-in

I don't own a truggy so I don't know for sure. Just speculation.

I run the HiTec HS-7945TH 0.12/250 OZ @ 6V-0.10/319.4 OZ @ 7.4V for both and they are great.My friends run the JR 9100 series servo( they like the 3 year warranty). The SAVOX servos are really desent and price is great.One of our other friends runs MKS servos the HV767 0.14/347.2@ 6V-0.11/430.5@7.4V this thing is a monster,tit gears also for just over $100 good price too. On that 8IGHT T 2.0 make sure you shim those servos up off the chassis or get the new servo/radio tray ( about $50) or you'll end up with some exspenive paper weights.

Since my 8T is nitro I used the rubber grommets when installing the servos and that was all I needed to keep my servos from sitting on the chassis.

Hi Guys

I run both buggy and truggy and I have been running a faster speed steering servo to make it reactive like the buggy and then a slower throttle brake to make my driving smoother. I was running a jr which put out specs of .07 and 17kgs and then for throttle brake duties a hitec 7955 which is 24kgs at .15 on 6v.

Could someone please explain why you go for a faster throttle brake servo and what minimum kg rating you would recommend for steering and throttle brake as i'm in need of some new servo's.

thanks.

Definatly use the rubber gromets they absorb alot of the vibrations and get the new LOSI GEN3 radio/servo tray,it puts both of the servos up front( improves your turn in) where there is less of a impact factor.
