Will this work with most 1/12 radio systems?

Yes, it uses standard micro servo cabling and should interface with most receivers, but verify connector orientation and pinout before connecting.

Is the servo suitable for endurance running?

Its construction supports regular use, though monitoring temperature and avoiding stalls will extend service life.

Can I upgrade the output gear later?

Some racers replace worn plastic first gears with compatible spares; check part availability and fit before attempting gear swaps.

What wiring colours should I expect on the cable?

The cable is black as supplied, but check the connector pin order on your receiver to ensure correct polarity when plugging in.
