For those who are unfamiliar with the plane it may be found on this site among others:

I see that it is a 3-channel plane. IMHO you should have a 4-channel plane but 3 is fine too if that is what you prefer. This plane will not have aileron control. Directional control will be done with the rudder just as it was done for many years before 4-channel planes were developed.
What nobody has mentioned yet is that you should get the help of an experienced r/c pilot to learn with. These fly different from full scale if you are thinking any full scale experience will help you. Skilled assistance will greatly increase the likelihood of successful flight.
Enjoy your new hobby and welcome.
