I got my solution- I followed Southwest&blue's idea but instead of cutting the nose wide open I managed to cut the centerline (where you glue the shell together) of the plane and put a magnet weight on it.
There are goods and bad.
The plane has a small gap in the front n' center area.
The magnet makes the plane move without you touching it.(by holding another magnet near the nose)
The Planes nose is finally in the downright position
Well that's all I can think of.
