When I got to the plane I saw that about 1/2 of one blade was gone. An unbalanced prop had caused the damage. The tail assembly shook completely off and the fuel tank shook itself back into the cabin. My landing prop strike probably weakened the prop. When I throttled up the prop failed and started shaking the whole plane. This separated the throttle linkage which kept it at full throttle, causing more violent shaking. The engine finally shut off when the fuel tank disconnected from the engine and slid back into the cabin.
Lesson learned ... With any kind of a prop strike, one should end the flight and inspect for any damage. Don't take a chance. Fortunately the damages to the LT-40 were relatively minor and nothing that epoxy glue cannot fix. A word of warning, with electrics they will keep running even with a busted prop as long as they are supplied with electric power. Throttle back as soon as you hear a strange noise since you might get your plane into a similar problem. A couple of years ago I had this happen to my electric SmoothE. It tore the forward half of the plane apart when it threw one blade.
