The Kyosho UB044 wing stay set is a direct replacement designed for the Ultima RB7.5 to restore correct rear wing position. It helps maintain predictable rear grip and stability when pushing hard around the circuit.
Targeted for the Ultima Series, the wing stays are made to precise tolerances so the wing sits consistently each run. That steady mounting reduces flutter and helps the RB7.5 hold line through high speed corners.
Whether you are refreshing worn components or fitting spare parts between events, the Kyosho UB044 keeps your RB7.5 performing as intended without complex modification.
