Hey Joe;
You may be surprised at how crash worthy a helicopter can be. Depends on the situaton, but yoiu will always break some parts, and with today's materials, they sometimes just bend. The main fuselage is a tight little bundle and pretty sturdy.Lots of time is spent dis-assembling, then replacing parts, then reassembly and trimming. Lots of time involved but sometimes not much money for parts. A typical "crash kit" for a .30 size heli is still under $100 I think. When talking to people at the hobby shop I have worked part time at for the last 30 some odd years, I tell them learning to fly helicopters is a lot like being married, a big commitment of time and money. I used to spend as much time talking people out of buying a helicopter as I did trying to sell one. The big thing, especially today is the safety aspect of it. Play the video again and listen to the sound of the rotors as the tips break the sound barrier. Imagine that carbon fiber blade hitting you at that speed? If you ar flying an I/C combustion engine, you may stall the engine and it will quit. May not happen with today electric motors. The pilot is standing in front of the heli, and that may or may not tell of his experience level, but I was always taught to stand behind it so as to help stay oriented to the controls, and if it alls go bad in some way, push the cyclic stick forward to get it away from you. I had a .40 size Schlueter Mini-Boy get away from me once in my driveway. It put a wood rotor blade through a hard wood garage door panel. That scared the crap out of me, I repaired it, trimmed it out and sold it soon there after.
Type at you later,
