| 4307-1025-0012 | 4307 Series Steel, MOD 0.8, Servo Gear (25 Tooth Spline, 12 Tooth) | Being steel, these pinion gears provide greater overall strength (as compared to brass or aluminum) ,Transfer the torque of your servo into a gear train with these MOD 0.8 servo gears. This 12 tooth servo gear is most commonly used to drive the 108 tooth hub gear, spaced 48mm away, in order to create a massive 9:1 ratio. For a more compact setup, it will also mate with a 48 tooth hub gear, spaced 24mm away to create a 4:1 ratio. Weight 2.2g Material Steel Tooth Count 12 25 Tooth Spline Gear Pitch MOD 0.8 Pressure Angle 20 Degree Quantity: pkg of 1 |

| 4307-1025-0015 | 4307 Series Steel, MOD 0.8, Servo Gear (25 Tooth Spline, 15 Tooth) | Being steel, these pinion gears provide greater overall strength (as compared to brass or aluminum) ,Transfer the torque of your servo into a gear train with these MOD 0.8 servo gears. This 15 tooth servo gear is most commonly used to drive the 105 tooth hub gear, spaced 48mm away, in order to create a 7:1 ratio. This gear reduction will increase the torque at the hub gear to 7x what the servo produces. The sacrifice will be the reduction in range of motion and speed by the ratio. Weight 4.1g Material Steel Tooth Count 15 25 Tooth Spline Gear Pitch MOD 0.8 Pressure Angle 20 Degree Quantity: pkg of 1 |

| 4307-1025-0020 | 4307 Series Steel, MOD 0.8, Servo Gear (25 Tooth Spline, 20 Tooth) | Being steel, these pinion gears provide greater overall strength (as compared to brass or aluminum) ,Transfer the torque of your servo into a gear train with these MOD 0.8 servo gears. This 20 tooth servo gear is most commonly used to drive the 100 tooth hub gear, spaced 48mm away, in order to create a 5:1 ratio. This gear reduction will increase the torque at the hub gear to 5x what the servo produces. The sacrifice will be the reduction in range of motion and speed by the ratio. Weight 6.1g Material Steel Tooth Count 20 25 Tooth Spline Gear Pitch MOD 0.8 Pressure Angle 20 Degree Quantity: pkg of 1 |

| 4307-1025-0024 | 4307 Series Steel, MOD 0.8, Servo Gear (25 Tooth Spline, 24 Tooth) | Being steel, these pinion gears provide greater overall strength (as compared to brass or aluminum) ,Transfer the torque of your servo into a gear train with these MOD 0.8 servo gears. This 24 tooth servo gear is most commonly used to drive the 96 tooth hub gear, spaced 48mm away, in order to create a 4:1 ratio. This gear reduction will increase the torque at the hub gear to 4x what the servo produces. The sacrifice will be the reduction in range of motion and speed by the ratio. Weight 8.1g Material Steel Tooth Count 24 25 Tooth Spline Gear Pitch MOD 0.8 Pressure Angle 20 Degree Quantity: pkg of 1 |

| 4307-1025-0030 | 4307 Series Steel, MOD 0.8, Servo Gear (25 Tooth Spline, 30 Tooth) | Being steel, these pinion gears provide greater overall strength (as compared to brass or aluminum) ,Transfer the torque of your servo into a gear train with these MOD 0.8 servo gears. This 30 tooth servo gear is most commonly used to drive the 90 tooth hub gear, spaced 48mm away, in order to create a 3:1 ratio. This gear reduction will increase the torque at the hub gear to 3x what the servo produces. This gear may also be used to drive a 30 tooth pinion gear spaced 24mm away for a 1:1 ratio. Weight 11g Material Steel Tooth Count 30 25 Tooth Spline Gear Pitch MOD 0.8 Pressure Angle 20 Degree Quantity: pkg of 1 |

| 4307-1025-0040 | 4307 Series Steel, MOD 0.8, Servo Gear (25 Tooth Spline, 40 Tooth) | Being steel, these pinion gears provide greater overall strength (as compared to brass or aluminum) ,Transfer the torque of your servo into a gear train with these MOD 0.8 servo gears. This 40 tooth servo gear is most commonly used to drive the 80 tooth hub gear, spaced 48mm away, in order to create a 2:1 ratio. This gear reduction will increase the torque at the hub gear to 2x what the servo produces. This gear may also be used to drive a 20 tooth pinion gear spaced 24mm away for a 2:1 overdrive if you're set out to increase the rotation of the servo. Weight 18g Material Steel Tooth Count 40 25 Tooth Spline Gear Pitch MOD 0.8 Pressure Angle 20 Degree Quantity: pkg of 1 |
