Fast delivery, great comms, smooth and painless transaction, always a pleasure.

Can I run this on a 2S LiPo through an ESC BEC?

Yes, you can power the Futaba S9451 from a regulated BEC output that supplies a stable 6.0V. Ensure the BEC can handle the servo current draw under load.

Is there any special mounting hardware needed?

The S9451 uses standard servo mounting flanges; the updated design improves fit. Most 1/10 cars will accept it without extra brackets but always confirm screw lengths.

How loud is the servo during operation?

Thanks to the coreless motor and dual bearings, the S9451 runs quietly compared with brushed types, producing minimal whine at typical steering speeds.
