I know that :lol:

Just 486oz on a throttle even with epa set it just makes a mental picture of someone gunning the throttle and a crab slide flying out through the body on the side of the car... :lol::lol:

I mean come on don't tell me that picture didn't cross your mind when you thought about how much torque is in one of those bad boys. I know it would be very unlikely unless you just had a major brian fart and didn't set your EPA but still.

thats why most claimed issues with manufacturers are chocked up to user error;):D

On the flip side of that, have seen the braking on a truggy with 486in/oz of torque? I got my truck to do a front flip at full lock and full speed. It's a sight to behold.

It's nice being able to go into a corner hotter and deeper and know that you have the brakes to pull it off.

They aren't the quickest but they are very fast. A 7950 in the Throttle though!!

Are you trying to pull your carb slide out of the carb with a servo. :lol:


Those things are a beast on Torque a little to much for the throttle if you ask me, but yes you could run them there if you choose too. 486oz of Torque on the carb is pretty intense.

i ask only cause i hear about some problems with the 7940. i'm not 100% sure if i want lipo yet, so thats why i ask if a 7955 or 7950 would be to slow for buggy steering or throttle/brake use. looks like .12 for the 7950(on lipo) and .15 for the
7955 (on nimh). also it would be great to only have 1 kind of servo that way i could switch it out if one fails for t/b or steering. i've always had .10 or less as a buggy steering or
throttle/ brake servo, so would i notice a difference???

well i just put 2 new 7940's in my buggy.

now everybody is saying they are crap :cry::cry::cry:

i was planning on these being the last servos i will buy for at least a couple years. now im not so sure :(

The only issue I had with the 7950 on the throttle was stripping the Losi horn inserts under braking. I had the EPA set perfect on the throttle but was too aggressive with the brake. I toned the brakes down a tiny bit and installed an aluminum throttle horn.

thats a whole lot of 0's V :lol:

Yes both the 7955 or 7950 would have plenty of speed for a buggy in steering or throttle.

You can run the 7955 on direct lipo with out any issues as well. It will probably make it a big stronger and faster as well.


A front flip from braking thats pretty sweet. I have only seen indos so far no one pull a full front flip out the bag though.:nod::nod:

they might treat youi very well as they have others , hitec is always a killer choice for servos . wait until you see the new touchscreen radio :eek: oops did i say that :confused:;)

:eek::eek:

I have heard Integra dropping hints that they have one on the horizon, but the Touch screen comment you just dropped is a first.

Sounds like someone at Hitec is thinking about the big kid in all of us that wants all the baddest stuff electronic wise we can find!!:nod:

Can't wait to see pics and specs on this one.
