Abstract
A model airplane engine starting stick is provided with a blade edge engaging roller having a roller surface of a material which will grip the blade edge of the propeller when against the blade edge of the propeller to cause the roller to roll along the blade edge without sliding over and damaging the blade edge as the starting stick is moved with respect to the blade edge to rotate the propeller. The starting stick of the invention includes a handle by which the starting stick can be held and manipulated by a user and a roller attached to the handle to freely rotate or roll with respect to the handle.

- a roller mounted to the handle to freely rotate with respect to the handle and to be positioned against a blade edge of the propeller when the propeller is stationary before the model airplane engine is started;
- and
- a roller surface of a material which will grip the blade edge of the propeller when against the blade edge of the propeller and will cause the roller to roll along the blade edge without sliding over the blade edge as the starting stick is moved with respect to the blade edge;
- whereby the starting stick can be held and manipulated by a user with the roller against the blade edge to rotate the propeller and start the model aircraft engine without damaging the blade edge.
