RE: Speed limits
Jim,
One more point to consider every aspect of this hobby has it's own unique set of risks associated with it. For turbines it is the risk of fire. I think it would be really diffucult to classify fire as being any more risky than getting hit by a large gas powered prop plane with a 30+ inch prop, or getting hit by a helicopter with carbon fiber rotor blades, or getting hit in the chest by a trainer.
