Engine Compatibility
The Stinger engine manual lists an M8 × 1 prop hub center thread for the following models:
- 15cc SE and RE
- 20cc SE, RE, and Twin
- 26cc SE and RE
- 30cc Twin
Confirm the center thread on your specific engine and match the spinner screw to the adapter. The propeller and spinner backplate thickness also affect which adapter length you need.
What's Included
One spinner adapter nut in the selected length. Engine, propeller, and spinner are sold separately.
What You Need
A compatible Stinger engine, propeller, center-bolt spinner with backplate, and a center screw that matches the adapter thread.
Setup Notes
Dry-fit the propeller, backplate, adapter, and spinner before final installation. Check that the backplate seats flat and that the center screw tightens the spinner securely without bottoming out in the adapter. Follow the engine and spinner manufacturers’ installation instructions.
