REDS On/Off-Road RTX Rotary Backplate (3.5cc Engine)

The REDS On/Off-Road RTX Rotary Backplate is designed specifically for REDS 3.5cc (.21) nitro engines. Its rotating design allows the backplate to rotate together with the connecting rod, reducing friction within the engine and helping provide faster RPM build-up and more stable idle speed.
