I use to fly RC helicopters. It is best to get a RC simulator like RealFlight. All the Pro RC flyers have RC simulator to practice 3D flying.
I bought a Zagi (Zagi - The Original EPP Foam RC Flying Wing
) years ago to learn how to fly planes. It is basically a foam flying wing with the prop on the rear. It was design for combat flying. The goal is to bump the other planes out of the sky. You can crash a zagi into the ground and it will survive where you can continue to fly. It is the best thing for kids on low budget.
