Can you have too much torque/speed for throttle servo?

For my upcoming Vesla.5 Gas build I just purchased an AGF-RC 78kg servo (0.082 sec / 1084 oz-in) FINALLY! I am also OCD and want matching servos. I used a set of Hitec D-845WP servos in my Vekta.5.

So the question for my lack of experience:
I know using the 78kg AGF-RC servo for throttle seems like it will be wasting it's potential, but is it too overpowered for throttle control? That is a lot of torque moving pretty fast.
 
The servo should be moving just enough to fully open the carb.You will fry it if the travel exceeds the point the carb is fully open.Now the servo will help immensely when applying brake but don’t go insane or it won’t last long.Set your endpoints
 
@Ferrebee88 I've heard too many stories with hitec so I avoid them. I would recommend the power hobby 701mg as it's 80 bucks and is just as powerful as the agfrc servo but I cannot as my last test and tune with the 5ive t on throttle/brake duty got so hot it started to glitch out. I have 3 more that's fine but I get it servos are luck of the draw, so with that said I'd go with the savox sv-0236mg servo. I've used that in a few 5ive's as well as my vekta .5 and it was great with no issues plus it gives all you need for speed and torque to pull on the brakes.

I know I said the agfrc was overkill for throttle brake but for 80 bucks a strong servo is hard to beat, when I ran my 5ive for racing I brought a backup 5ive so everything interchanged so if I needed servos or something I stole it from the other so that's why I had an overpowered servo for throttle plus I used the same for steering.
 
So far I haven't had any issues with the Hitec servos in my Vekta. I will probably go with the Savox 0326. I actually have one of those handling the steering in my Baja b5 electric and it's held up to some abuse. Have you had any issue running the savox on straight 2s battery? I have a BEC in the Baja so it's regulated to 7.4v.
 
Sweet! I getting antsy waiting on my Vesla builders kit, so I am overthinking a bit.
Heck, maybe I'll just swap the hitec from the Vekta to the Vesla and put the AGF-RC 78kg in the Vekta for steering. I bet those oversized trepadores could use the extra torque.
 
The speed on the agfrc is pretty fast, you'll be happy with it. Also you may want to tighten up the servo saver as the servo will power through the break over of the spring tension
 
The 78kg and the 100kg are the same price, though the 78kg moves faster. 0.082 for the 78kg and 0.110 for the 100kg. Is the speed difference even noticeable? I’d rather have the added power of the 100kg but am curious to know what the group thinks.

I’m getting ready to build the Vesla kit and doing some research on the components I’ll need to complete the build.

TIA
 
The real answer to all of this is both servos are overpowered for the application and not needed. These servos shine at low vehicle speeds with their torque not at moderate to fast bashing speeds. If your racing and are on tight technical tracks then sure I can get behind that as I use the 78kg in an mcd on a tight onroad track.

If you want it just to say you have one then yea go for it.

I’m just trying to get a steering servo that fits and does the job. I’m not one who needs a brand or to spend a fortune when there’s something available that does the job for less.

Edit: I use the primal 13130 in my Kraton and think it does a fine job. Id get another for the Vesla if it fits, but im not seeing servo dimensions anywhere just yet. Might wait for the car to show up to figure that out.

I guess but the dimensions are set in stone and there's servos that fit without modification. You chose are servo from a company that made its own servos to fit a vehicle they built. The vesla is a true 5th scale and it will take any standard 5th scale sized servo and it probably won't allow a raminator servo to fit without a bit of modification.
