After more than 6 months of development and testing we are excited to launch our latest servo, the M1 SR SERIES 55KG digital programmable servo.

Succesfully proven across the globe in 1:8 scale electric and nitro buggy and truggy at some of the largest events in the world as:

• 2024 Dirt Nitro Challenege.

• 2024 Psycho Nitro Blast.

• 2024 Silverstate.

• 2024 RCRA Queensland State Titles.

• 2024 Philippines Masters.

• And many many more regional events across Australia and the USA!

We wanted to make something special, we updated the design and the materials used including:

• New hardened stainless steel gears matched to a new hardened retaining pin with reinforced housing in the servo case.

• Bearings, the new design now utilises 4 dustproof ball bearings,

• A new high torque 4-pole brushless motor, increasing the torque and speed. We have updated the case and motor housing now encorporating all alloy 3 piece construction elimates flex and any side sway spline movement.

• An updated logic board, being Mach-1 its programmable!

Of course we kept our precise magnetic encoder which allows the servo run in very humid conditions.
