Specifications Parameter Details Torque 32 kg-cm (444 ozf-in, 27.8 lbf-in) @ 8.4V (Fully charged 2S LiPo). For best results, pair with our Steel Servo Horn! Voltage 5-8.4 Volts (you MUST use a Motherboard, UBEC, or BEC to power this servo if your battery is 10V/3S or higher) Current 0.1 amps idle (typical draw depends on load). Peak/Stall current varies by voltage: – 5V, approx 2.7A – 7.4V, approx 3.9A – 8.4V, approx 4.4A Weight 66 grams (2.33 oz) Dimensions Standard 20mm width, full CAD model provided here. Wire Length 100mm (for older 180-degree version, 85mm) No Load Speed (6V) 0.238sec/60° (42RPM), (7.4V) 0.192sec/60° (52RPM) Included in the box: 5 different plastic servo horns Rubber shock isolation mounts M3 servo spline screw Four mounting screws Design Considerations: Our testing shows that you can expect 32kg-cm of torque or more when operating this servo with 8.4V to provide this power. This is the same voltage provided from a 2S lipo without a BEC. This servo has a custom controller so standard RC radio equipment will provide a true 200-degree range of motion with the usual 1000-2000us RC signal. No range extender is necessary! Pair with our custom Motherboard to avoid smoking your servo with a larger than 2S battery and Servo torque is measured in units of torque, which is force * distance. This is very intuitive as it’s simply the lifting force provided by an arm of that length. For example, this servo 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…) Just ‘Cuz recommends designing so no more than 70% of the peak torque is needed to lift your target mass at the end of your arm. This allows a safety factor in your design. For example, 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. ItGresa Robotics is proud to support the builder community by offering and marketing their products. Just ‘Cuz Robotics has quickly become known for both incredible product innovation and technical support for the community through their great videos. We are proud to be one of the very first distributors to partner with them and help bring their incredible products to a broader market. Warning: combat robots are not toys! They are extremely dangerous. Click here for a safety video. Testing a robot with an active spinning weapon should never be done while maintaining a line of sight with the robot. Ideally, you should be testing inside an enclosed box or arena with at least 1/4″ thick polycarbonate windows or top to see through, and 1/2” or thicker plywood or MDF construction. Operation (Including testing) outside of a suitable arena or test box could cause serious injury.
