Dr Oakenford you are WAY off the mark mate!
Recreational aircraft fly many thousands of hours and the "crash" rate is comparable to that of GA given the hours flown. Your comments "many ending in fataility" are also inaccurate when compared to GA. The crash rate for RA-Aus is the same comparably as it's been for many years. There are currently over 7,000 members who are mostly pilots and many hours flown.
One of the main problems is owner maintenance, particularly of 2-stroke's, but not limited to. The tendency is there to save a few dollars on maintenance, but this rarely ends in fatalities. Probably 95% of the 2-stroke's at any airfield have suffered an engine failure at some stage, but they are still in one piece! RA-Aus training emphasises action on engine failure and usually results in no damage to the aircraft or pilot. I wish GA training had a similar focus on engine failures in flight.
