Prolux Replacement Rubber Starter Cone For Hand Held Electric Starter

The Prolux Replacement Rubber Starter Cone (Part No: PX1275-1) is a high-grip, durable insert designed for standard handheld electric RC starters. Over time, the friction and heat from starting nitro engines can "glaze" or tear the original rubber; this replacement restores the necessary traction to turn over stubborn or high-compression engines without slipping.

Key Features:

• High-Friction Compound: Manufactured from a specialized rubber blend that balances "grab" and longevity, ensuring it grips the spinner firmly even if a small amount of fuel or oil is present.
• Tapered Internal Profile: Designed to fit most standard aluminum starter cups, providing a snug friction-fit that won't spin inside the housing.
• Universal Spinner Compatibility: The recessed cone shape accommodates a wide variety of spinner sizes, from small 1.5" diameters to larger 3"+ spinners found on .60 to .90 size aircraft.
• Heat Resistant: Engineered to withstand the momentary high temperatures generated during prolonged "dry" cranking sessions.

Maintenance Tip:

If your starter cone is slipping but doesn't look worn out, it may be "glazed" from heat. Pro-Tip: Use a bit of medium-grit sandpaper to roughen the inside of the cone; this will remove the shiny, slick surface and restore its grip. When installing a new cone, ensure the metal starter cup is clean and dry; if it still spins inside the cup, a tiny drop of thin CA glue or hairspray can help lock it in place.
