Remark :

Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

What steering horn should I use with this servo?

Choose a horn that gives the steering throw you want while keeping leverage reasonable. Shorter horns increase response but raise load, so match the horn to your servo and car geometry.

Can I run this servo on a 6.0V system?

Yes, the servo operates across 6.0V to 7.4V. Running at 6.0V will reduce speed and torque slightly but can still provide reliable control for many setups.

Is this suitable for drift setups?

The quick response is useful for drift cars that require sharp, repeatable inputs. Adjust Selector4S settings for smoother transitions and reduced twitchiness when counter steering.
