Digital Servo and ESC Tester with 3 Modes, 3 Outputs

Pocket-sized servo and ESC tester for checking, centring and comparing servos and ESCs on the bench without a radio or flight controller. It is handy when building fixed-wing models, setting up gimbal or payload-release servos, or calibrating ESC throttle range on a multirotor.

Key features

• Three modes: Manual (the knob sets the position), Neutral (centres at 1.5 ms) and Automatic sweep.
• Drives up to 3 servos or ESCs at once, so you can compare their response side by side.
• Output signal of 1.5 ms ±0.5 ms, covering the standard 1.0–2.0 ms servo range.
• Runs on 4.8–6 V DC from a 5 V BEC or a 4-cell NiMH pack.
• LED indicators in a 35 × 30 × 20 mm, 7 g case.

Specifications

• Operating voltage: 4.8–6 V DC
• Output signal: 1.5 ms ±0.5 ms
• Outputs: 3
• Modes: Manual, Neutral, Automatic
• Dimensions: 35 × 30 × 20 mm
• Weight: 7 g

Do not power it straight from a 2S LiPo: 8.4 V fully charged is above its 6 V limit, so feed it through a BEC. Remove propellers before testing an ESC with a motor attached.
