I almost hit a big crow one time......he flew right into my flightpath. I'm guessing if I would have hit him he wouldnt have had the insurance coverage anyway. LOL. I agree after a bad crash there is no positive way to identify what was the cause factor since the force is so tremendous on the fragile aircraft and the electronic parts inside. I hit so hard one time I found the elevator pushrod sticking out fo the dirt 15 feet away and buried 3-4 deep in the ground. That one was my fault [:-] and no fault of the manufacturer. I also had a close call a while back with my rascal 40 , I lost one of the tailwheel springs after 3 flights and was attempting to make a new one from a spring I had in the field box ,when all of a sudden I was standing there with the rudder in my hand !! It pulled clean out of the horizontal. I couldnt believe it !! I had checked this before the start of the day and have probably checked it 20 times before and it was secure. Just makes a person stop and think where did I go wrong when I glued it in. I reglued it in and it has has 5 flights since without a problem but you can be sure I really check things over now before each flight. There ae so many things that can go wrong that i think if the manuf. could just step it up a little it gives us a little edge over what we do wrong. Just one less problem to worry about.
