MBX6 like the stronger servos .I am not gonna sugarcoat it but with 115 oz may going to push in the turns....U will see it...I drove mugen for 3 years (mbx5r and mbx6) specially mbx6 like to be forced in the corner...get something above 200 oz...just my 2 cents...

I've had descent results with hitec 7955, 7950, 7940 and I still like ko rsx servos but they are very pricey. I just ordered some Savox hv 1268 servos. With 361 oz of torque and at .11 speed I'm going the use them on both throttle and steering. I don't think the speed servos that move at .06 are quite built for the abuse of 1/8 scale. I just wish the servo companies could settle on the same size servo horn.

I have had this servo in my MBX6 for about 20ish races/pracitce days this season and have had no trouble at all and it out performed my old JR with 200oz. of torque, and for the price you really can't beat it in my mind.

Talking Hmm

Steering Servo is a topic I like to get into.

I think the more the better. This is because (Especially in a truggy) the more torque, the better. If a servo is rated at 250 in oz, and you exceed this due to one really hard turn, then you put a lot of stress on the servo motor. More torque draw, the more power it will require, which in turn means more heat. I have been running Airtronics 94157 up to the 94357 product line for a long time and I think they are great in a 10th scale buggy. 1/8th scale is heaver and I believe more current is needed turn even the smoothest of buggies reliably and in order to get years of enjoyment.

I would say about 250 in oz for a buggy is minimal. I would also say for a truggy, Min 350 in oz. I think it's Hitec with 600 in oz???// Yeah...

Basically, when I want the think to turn, I want it to turn now and not think about.

Of course cost is an issue, but, buy a really over rated servo, and you should never have to worry about the darn think...ever..

BTW - 600 in oz of torque could get you into trouble because it's so strong, it could break the mounts it sits in. Be sure to setup the end points on any servo before taking the car /truck out to race.

Also, don't think you can hold back the servo with your finger. I tried this with a 300 in oz servo and I lost. (Got smashed but, didn't loose a finger, just really hurt )

After reading the above posts I think that my measly 125 in/oz servo isn't going to cut the mustard (at least not very long)... So I have started looking for a new servo... The problem I have found now is this... I can find a servo with good Torque but the seed goes up (some) and to get good speed I give up some torque. What speed should be acceptable to me? I have seen servos with speeds from .06 to .30... What gives???

For instance the Spectrum S6030 has 278 oz-in of torque at .15 sec for ~$85 but the S6040 has 167 oz-in at .08 sec for ~$79

Typically, you want higher torque for steering applications and higher speed for throttle applications. There is a torque/speed tradeoff, but more torque is necessary to turn the wheels and more speed is necessary to have a smooth throttle input.

I think I found a good servo... I got a Hitec 5955 TG at 6V it has a stall torque (whatever that is) of 333 oz in and a standing torque (again no clue) of 433. Even thoug I don't know what Hitec means by stall and standing torque I figure the lowest torque it will have is 333, so it should be good... right?

Thats a very good servo, I have a few that were used when I got them and have been running them for over a year.
