Feetech FT3325M 6V 7kg.cm 250° Mini Metal Case Digital Wing Servo

The Feetech FT3325M is a 10 mm-thick digital wing servo in an all-aluminium case with metal gears, made to sit inside thin wing panels and tail surfaces on fixed-wing aircraft and VTOLs. It delivers 7 kg.cm at 6 V and 9.5 kg.cm at 8.4 V across a wide 250° travel.

Key features

• 30 × 10 × 35.7 mm case fits slim wing servo bays

• Runs on 6–8.4 V, so it can be powered straight from a 2S LiPo or an HV BEC

• 0.095 s/60° (105 RPM) no-load speed at 8.4 V

• Standard PWM input with a digital comparator amplifier

• 25T 4.95 mm spline with a POM horn and 250 mm lead
