I had a good flyer once tell me that I should always let another fly the maiden flight in part to eliminate the anxiety that one feels when something he has constructed in put to the ultimate test. I have followed that and found it to be true, however I have also found that my anxiety is now less at first flight and I can do the maidens myself. If in doubt go with the noninvolved other flier. Be sure he is a know quantity and not just another wannabe.
