if you are talking 1/8 scale nitro and electric, that is a false statement...

I've been running that servo on my cars for the last 3 years as a throttle servo. It's now in my mbx6 and it's still working perfectly

This servo right here:

Stops both my Buggy and Truggy with ease. It's only 98 oz in torque. It can lock up all 4 any time I want/need it to on dirt or concrete.

For the throttle response in a ESC vs. a servo, yes the ESC is "faster" but I can guarantee you will probably not feel any difference using any .5-.6 servo. That one I linked is .032

In the end it all comes down to what you want to pay for.

The listed servo is only 98oz when a Lipo is used. Is the OP using LiPo? Anyway, it's too expensive ($120) for so little torque. I doubt a newcomer would appreciate it's speed.

I would shop around for a Hitec and no need to pay full retail. This Hitec for almost half the price should be plenty.

I had that same exact question. I was replacing the throttle / brake servo on my Kyosho TKI3. A poster told me 150+ is totally sufficient. I bought the blue Radio Post servo. On 7.4 lipo its only pumping out 165 oz, but turns 60 degrees in .04 seconds. If I have my brake epa set to 100% its too much braking. I have it dialed back. Bottom line, 165 oz is more than enough for throttle / brake just as the poster told me it was. My friend who races a MBX6R uses the same servo for throttle / brake and he has no issues either. Also, the radio post servo is way smoother (and faster) than the Savox SC 1268SG I replaced which I suspect is due to a higher bit rate.

That is one of the servos that I have and was going to try out for the throttle/brake.

Yes I will be using Lipo.

160+ oz of torque is enough, but, this is how I see it and was told by a hitec rep. Always get the most amount of torque you can. I run 300+ on all my 1/8 vehicles. In theory, if it takes 160 to run the gas and brake then that's fine. But you will be using ALL that servo has to offer every time you hit the gas and brake, where as if you use the 300oz servo you will only be using a little over half of its capability. Therefore you can turn your EPA down to desired effect and your servo will last much longer than the one that is being tapped out every time you turn it on. Let's face it, servos are not cheap so the fewer I have to buy the better. Take this for what it's worth as it is only my opinion and I'm sure others have had great success with lesser servos. Good luck in your decision and glad to hear of another racer joining the nitro scene.

Anyone using a Hitec 965MG for throttle/brake?

bob.less

Thats what Ive been useing. works fine 4 me .

Thanks I think that's what I'm getting...

I always subscribed to the idea of more power on the steering than on the throttle/brake. Then I seen a few pictures of some of the cars at the world's race right now and they had the power servo on the brake and the speed servo on the steering. Ronnenfalk for example runs ko propo and is set up that way.
So idk.. go with whatever makes you feel comfortable I guess lol.

I run the Hitec 7955 for both throttle and steering. Bullet Proof setup.

The Specs on that hitec listed above look perfect for what you are after and $$ is good too

EPA simply limits the end point of the sweep for a servo. I'm not understanding what the "desired effect" would be there. Perhaps you meant Expo(nential)? That determines how quickly the servo moves from neutral.

The Hitec 7955 is a solid setup and if you run the same servo for both applications, you'd only need to carry a single backup (not that you really need them running Hitec). I run 7940s on throttle; they are snappy, quite strong, and exceptionally reliable.
