RE: How to prepare a plane for maiden Flight?
Another good thing..........have a disinterested third party look over you plane before your first flight. A "fresh" set of eyes might catch something as little as leaving a screw out of a servo. Remeber you've been looking at that plane for days, so its easy to miss the obvious.
Next take off and get some altitude.......don't go crazy and climb straight up, but let the model climb. Then trim it out, and fly it around. Bring it in when your done and like those guys said above.......recheck the plane, you never know what might come loose.
Rember this though.......nose heavy is better than tail heavy. If your tail heavy, even slightly, it makes the pitch (up or down) very twitchy. Also the plane will tend to hunt for up or down. Also makes landing harder as you have to push the plane into the ground. I would balance just slightly nose heavy or even.
