FAQ

Is the Futaba HPS-CB701 suitable for 1/10 and 1/8 RC cars? Yes. The Futaba HPS-CB701 is listed for 1/10 scale on-road and off-road RC cars, as well as 1/8 scale on-road and off-road RC cars.

Does the HPS-CB701 support S.BUS2? Yes. The HPS-CB701 supports PWM, S.BUS and S.BUS2 command protocols for compatible Futaba radio systems.

Can this servo be used with a BEC? No. Futaba states no dry battery or BEC use for the HPS-CB701, so OZRC recommends following the Futaba manual carefully when selecting the servo power supply.

Does this servo support SR and UR modes? Yes. The HPS-CB701 supports SR mode with compatible Futaba transmitters and UR mode when used with compatible Futaba T10PX equipment.

Important Notes

• No dry battery use.
• No BEC use.
• For RC cars smaller than 1/5 scale only.
• Use a suitable high-discharge receiver or servo power supply as specified in the Futaba manual.
• Check transmitter, receiver and servo mode compatibility before enabling SR or UR mode.
• CIU-2 or CIU-3 USB adapter for PC programming is sold separately.
• Install with secure mounting hardware and check steering end points before driving to prevent servo overload.
