RE: how often do you crash on your maidens?
When I 1st got in the hobby I let other people maiden my planes; the 1st one I maiden was a super playmate (.25 size) and reversed the ailerons just flipped over on take off and broke the vertical and prop. I repaired it in 15 minutes and flew it. Same day a fellow club member ( i won't mention his name because he is a well known flier) tried maiden his Yellow Aircraft P-38 with the ailerons reversed and totalled it.
Now I always let another flier check out my plane before I maiden it.
