Just one more footnote to this sad event, I was doing the weighing for the contest and the day before the accident when weighing the ship involved the pilot asked me what the tail and fuselage weights were. I asked him why he wanted them. His response was that he was not sure where his CG was. I informed that the weights I had were not usable as the glider was not set at the appropriate angle for CG calculation. Not sure he understood what I was telling him. I did not give him, or anybody else during the contest, the weights for the main and tail as the only weight that was important to the contest was the total weight.

I knew Tim and he was a skilled machinist who worked his way up to owning his own company (which is why he could buy such nice toys). He was also a pilot for many years. He started in hang gliding, got into power planes, flew and owned his own twin engine and one or two sailplanes previous to the ASG 18 meter.
I would think he understood that the CG must be measured with the fuselage at a certain angle. It sounds like this particular ship may have had something wrong with it CG-wise.
