Brushless All Metal Speedy Servo - 42kg-cm True 200 Degree

If you want to upgrade your SSP kit or add a super-powered servo to your next bot or project, look no further!

Compared to our budget 32kG servo, this servo is a bit heavier, but physically shorter as well as almost twice as fast and a bit stronger. It's a drop-in replacement for most standard servos - just keep in mind the wire exit location is different due to its shorter length!

Most of the cheap servos on the market flat out lie about their specs. Those labeled for 270 degrees barely provide 180, and the torque ratings vary from misleading to flat-out lies. Not only will this servo deliver the angle and torque that it says on the tin, but it’s specially optimized for use in combat robots.

By implementing stall protection, the current draw of this servo will limit itself to about 20% after it is stalled continuously for more than 8 seconds. Remove the stall condition and after a few seconds, you can expect to get more power once again over and over, without needing to worry about smoking your servo motor!

• Torque: 42 kg-cm (583 ozf-in, 36.5 lbf-in) @ 8.4V (Full charged 2S LiPo). For best results, pair with our Steel Servo Horn!
• Voltage: 5-8.4 Volts (you MUST use a Motherboard or BEC to power this servo if your battery is 10V/3S or higher)
  
• Current: 0.18 amps idle (typical draw depends on load). Peak/Stall current varies by voltage.
  
• 7.4V, approx 4A
  
• No Load Speed: 0.142sec / 60 degrees (70 RPM)
• Weight: 77 grams (2.72 oz)
• Dimensions: Standard 20mm width, full CAD model provided here.
• Wire length: 100mm

Includes all parts pictured including 5 different plastic servo horns, rubber shock isolation mounts, M3 servo spline screw, and four mounting screws.

Expect a proportionally lower current and torque at 5V/6V than 8.4V, this is true of all servos.

Additional Info

“How do I design a lifting arm?”

Servo torque is measured in units of torque, which is force * distance. This is actually very intuitive as it’s simply the lifting force provided by an arm of that length. For example, the weaker servo we sell can lift 32 kg with a 1cm arm or 27.77 lb with a 1-inch arm. (This is over 60 pounds with a very short arm! Avoid getting your fingers pinched…) I recommend designing so no more than 70% of the peak torque is needed to lift your target mass at the end of your arm so there is some safety factor in your design - this means at most a 22-inch arm for 1 pound, 7.4-inch long arm to lift 3 pounds, a 5-inch arm to lift 4.5 pounds, etc. 

Warning: While servos are less dangerous than spinning weapons, it is still strongly recommended that a weapon lock be used with servo-powered weapons as it’s easy to create pinch points with servo-lifting arms and saw arms.
