RE: how do i fix and fly a firebird scout

Page 19 of your Scout manual explains how to adjust the stabilizer for the turning problem. Also make sure your wing is centered on the fuse.
And page 20 covers the adjustment for getting it to climb. A motor not producing full thrust can also be the culprit - this can be caused by a worn out (lube the motor bearings once in a while) or damaged motor or a battery that's shot or not fully charged.
Glueing the stabilizer is a good idea, just make sure you use the appropriate glue (foam safe CA or Gorilla glue or one of many others that will work for foam to plastic)
