Whether you do your own maiden or not depends on your confidence in your own ability, and the ability of others at your club.
I started to do my own maidens when I realised there were very few people who I was willing to trust with my new pride and joy. Now down to three others, though they would wonder why I was not doing it myself if I asked them anyway.
Having said that, for anything 90 size or bigger, and if possible smaller, I do like to have someone lend me a hand, as it just helps to take the pressure off a bit. Of course that is usually not a problem, I'm sure you all know what it is like when you turn up at the field with something new, everyone wants to see

I now help out with the maidens for others, which is a nice feeling [8D]. However, unless asked, I wont push other peoples planes very hard on these maidens, just trim it for level flight, and maybe do a simple loop or roll to make sure all is ok. Basically I don't want to break someone elses plane doing something silly with it.
The other good thing about doing maidens, is you get to fly other planes, ones you would not normally fly, which is interesting and all part of the hobby

Shahid, If you are not happy doing the maiden, then leave it to someone else that you are happy with. Last thing you want is to lose a plane to dumb thumbs when the only cause is nerves as it is a maiden flight.
