The best way to learn to fly RC Helicopters or RC Airplanes is to practice on a Flight Simulator.
A Quality Sim is worth its weight in gold, it will save you thousands of dollars in repair parts and
eliminate countless hours of set up and testing. Instead, you practice, you crash, you hit reset.
Simply repeat the process until you can take off, fly around and then land without crashing.
Now granted its easier said then done, but that is the basic concept.
Now when it comes to selecting a simulator, there are many to choose from in all different price
ranges from Free to more then $200. As you can imagine the Free ones are not the best but
they will give you the basic idea of what controls do what. The more expensive simulators are
nice but also they usually come with Specific controllers.
