MACH-1 RACING // M81SR 55 KG SR SERIES DIGITAL PROGRAMMABLE SERVO
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 utilises 3 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.
A new logic board, being Mach-1 its programmable!
Of course we kept our precise magnetic encoder which allows the servo run in very humid conditions.
