Not trying to sound like an ass, but you should probably accept the fact that you will crash someday.  It happens to everyone.  I have jitters everytime I take off.  And crashes suck.  But Ive never known anyone that hasnt crashed.  The advice the guy gave about flying your trainer alot more was pretty good. http://www.tompierce.net/SBD/index.htm  Go to this site.  This guy put 2 years into this build and it is spectaculer.  And then crashed on the first flight.  I probably would have been in shock for months but he seemed to take it all in stride.  Good luck to you..
