RE: How do you maiden your plane???
I believe that everybody who is "green" and starting out has someone else more experienced test fly their birds if available.
Just make sure you go over everything a few times before the first flight. Some people do a pre flight checklist.
Personally I never had this happen, have had more experienced flyers test fly it after I flew it a few times to give me a 2nd opinion.
If the bird is yours, you control it.
