Hi!
All aeroplanes turn by a combination of giving aileron and elevator ( forget about rudder for the time being).
You bank the plane with ailerons and "turn it" with elevator.....sounds strange perhaps but elevator is the command used for turning an aeroplane!
Your AEROBIRD was /is just a toy ...and as such it is very forgiving......Welcome to the real world of R/C flight.
-Lets see now... how the hell am I to do to hover this airplane?!

Regards!
