2wd Servo

[Benson]

I currently have a Goteck HB1621S HV Digital Brushless MG High Torque STD Servo 19kg / 0.07sec / 53g which now stutters. For £25 its lasted 6 months.

I'm after a replacement but wanted to know what would be the minimum KG's you'd recommend for a 2wd 1/10th buggy for racing both indoor & outdoor use?

Any servo recommendations would also be appreciated.

Many Thanks.
Benson.
