Can I use this in both electric and gas 1/10 cars?

Yes. The servo suits 1/10 electric and gas models provided you supply the correct operating voltage and check servo clearance at the mounting point.

Are replacement gears available for this model?

The unit uses hard alumite aluminum gears for longevity. For replacement parts, contact KO Propo dealers or specialist parts suppliers to confirm availability.

Does the heat sink make a noticeable difference?

Yes. The integrated aluminium heat sink helps dissipate heat during long runs, which can improve consistency in tight race conditions when the servo is under continuous load.

What speed and torque should I expect at 7.4V?

At 7.4V the servo delivers 0.09 seconds per 60 degrees and 12.5Kg-cm of torque, giving a good balance of speed and control for 1/10 racing.
