Fine-tune ULTIMA RB6 aerodynamics with Kyosho UM709

The Kyosho UM709 Wing Stay Set is made to sharpen the aerodynamic balance of the ULTIMA RB6. It provides a reliable fit to the RB6 chassis so drivers can expect steadier rear-end grip at speed.

Built for balance and longevity

These wing stays use sturdy materials selected to keep weight low while resisting wear. The result is a stable wing mount that helps maintain predictable handling during aggressive cornering and high-speed runs.

Fitment and straightforward setup

The kit is tailor-made for the ULTIMA RB6, allowing a clean install with common tools. Hobbyists can swap the stays quickly to test wing angles and get consistent results across different track surfaces.
Remark :
Due to limited stock availability, please notice that some Kyosho items may have to order from the factory and the ready time is around 4-6 weeks. 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.

Will the Kyosho UM709 fit older ULTIMA RB variants?

The UM709 is designed for the ULTIMA RB6 mounting points. Older RB models may need modification or alternate mounts to accept these stays.

What tools are needed to install the wing stays?

Basic hand tools such as hex drivers and a screwdriver are usually enough. Check your kit for any small hardware and tighten to the recommended torque.

How do these stays affect tuning options?

A firmer, well-mounted wing allows you to run more rear downforce with less flex, making aero adjustments more predictable when changing wing angle or endplate setup.
