This beast is the Hitec HS-805BB servo. Able to take in 6 volts and deliver an impressive 343 oz-in. of maximum torque at 0.14 sec/60°, this is a heavy duty servo and is not to be taken lightly!
This high quality servo is perfect for your mechatronic needs and if you are looking to get into robotics, this is where to start. The HS-805BB servo comes standard with a 3-pin power and control cable, Y-harness, and all hardware listed below.
Note: This servo can draw around 800mA, so keep that in mind when planning a power supply.
This skill concerns mechanical and robotics knowledge. You may need to know how mechanical parts interact, how motors work, or how to use motor drivers and controllers.
Skill Level: Competent - You may need an understanding of servo motors and how to drive them. Additionally, you may need some fundamental understanding of motor controllers.

Whether it's for assembling a kit, hacking an enclosure, or creating your own parts; the DIY skill is all about knowing how to use tools and the techniques associated with them.
Skill Level: Noob - Basic assembly is required. You may need to provide your own basic tools like a screwdriver, hammer or scissors. Power tools or custom parts are not required. Instructions will be included and easy to follow. Sewing may be required, but only with included patterns.

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Competent - You will be required to reference a datasheet or schematic to know how to use a component. Your knowledge of a datasheet will only require basic features like power requirements, pinouts, or communications type. Also, you may need a power supply that?s greater than 12V or more than 1A worth of current.

Is a really good servo for the price, is decent strenght at 0.14s make it good for robots with low PID necesities. Is a pity the taxes are so high in Spain :(
Wish it had a metal horn, other than that it's a good solid motor

I don't want to start a flame ware here, but only three countries in the world haven't officially adopted the metric system. I know Sparkfun is in the USA, but even American engineers use metric. Ounce-inches? An online search tells me it's 2.42 newton-meters, in case anyone was wondering.
As a REAL engineer in America, I have never once used English units, and I refuse to ever do so. Whoever tells you that they are disappointed in the rest of the world for not being able to convert, or too lazy to google, is either mental, too lazy themselves, or ignorant. Use common sense please. Somebody that endorses english, please tell me how it makes your life easier than metric, PLEASE!
As an engineer in America, I still use English units. I see that you got the information you needed from the internet, which probably took less time than complaining about the units.
As an engineer in America, I am disappointed in the rest of the world if they can't figure out how to convert units, or use google to find an online calculator that will do it for them.
From previous experience working with these servos, (And actually this servo specifically), I can say these things are quite powerful. Though on a side note, if you run them under high stress for awhile they do heat up slightly.
I've got a project that appears to require more power than this servo has to offer. I have to turn the servo 55 degrees in 3 seconds or less with a load. I'm using limit switches and don't need feedback. I have tried Nema 17, Nema 23, and now this 808 servo. This servo almost does it. Can anyone suggest a motor of any kind that might work for this?
Have you tryed using a vex robotics motor?
Can anyone suggest a servo and driver with 2 or 3 times the power of the HS-808BB?
Are there any ServoBlocks mounts for use with this servo?
Hi. I would like to know the answer to that question myself. I've been looking for options to connect this 808 servo to something else. I wondered what horns came with it and looked. Oh yeah! The little round one that comes with it is exactly what I was looking for, well, if it is metal.
Did you ever find anything to match up to the D1 spline? Seems that someone somewhere has to have something to fit this puppy???
best wishes, david
Any plan on stocking Hitec HS-5805MG?
Seeing as how the current expected purchase for 200 units was four days ago, can you provide a current expected arrival date? Thank you for reading.
Come on, it has Giant right there in the description. Please add photos with a ruler to give a quick idea of the size. And how about adding both metric and imperial units? Torque in oz-in and dimensions in metric? Just include both. And one more thing, SparkFun rocks!
Now to get a few of this for a giant T-rex project!
for what it's worth, you can check out the video above for a size comparison.
These looked kind of jittery in the product video. Would you say these are stable enough for something like a biped or other legged robot, or would it look like me after too much coffee?
I am building a robot that runs off of used cooking oil and was wondering if this would work to move the throttle up to accelerate?
I'm looking to design a dumb waiter type pully system for my loft, would this work? How much weight could it lift?
Just throwing this out there, this thing weighs as much as an orange and the screws are the length of a large mosquito - according to the Dictionary of Numbers.
