You won't have a great deal of difficulty flying the Aerobird even as a first timer. It will take you a few flights to get the hang of it then you will be all set. Keep it up high to begin with till you learn to control it. Back off the throttle to about half once you get some altitude and just sail around in big wide circles while learning the controls. When you start losing power that tells you the battery is dying so start looking for a place to land. When landing just let it glide down and settle in soft .
hint: if you are flying on grass leave the landing gear off..you won't need it and make slow deliberate control inputs rather than slamming the stick around and you will get smoother turns. *BE CAREFUL OF WIND...neither Aerobird nor Firebird handle wind well. A strong breeze can carry the plane away as it may not have enough power to fly through it. My brother has already had to cut a tree down to get his back. hehehe! I warned him.

Whichever bird you decide on have fun and good luck. Happy Holidays.
