You have described the engine as an sx-h, fb, and fp. Am I supposed to guess which one it really is? Please look carefully on the side of the motor and read the correct letters, don't go by what you see on the box.

The sx-h is a helicopter engine but the picture looks like an airplane engine.

You auction will do much better if you spell every word correctly. A used engine in good condition is worth about $30.
