Hi Dale
Good point on the greasy airplane. I am fortunate where I fly as we have starting stands. Even with that, these things are NOT toys and if they get away from you can tear you up pretty good. I have seen more that one injury resulting from complacency. The last one that I saw was done by a wood prop and the tendons, arteries and bones in your wrist are no match for a spinning propeller. The only good (if there is such a thing) was that the propeller was wood. I believe that the fool on the video had a composite MA on the engine. Imagine how that would eat you...
Just THINK when you play with these "TOYS",
