RC flight simulators can give you a very realistic radio control flight training experience, without having to leave the house!
Learning to fly radio control in this safe environment is as realistic as it gets without actually taking a trip to your local flying field. And of course it eliminates the dreaded aspect of learning to fly radio control - the damage zone! When learning to fly rc there's a good chance that your model will get damaged sooner or later, but learning on a flight simulator will help minimise those little 'incidents'.
Indeed, a big advantage with learning to fly on a rc simulator is that it gets you used to the 'reverse control', or 'reverse co-ordination', which is the term used when the aircraft is flying towards you and the turns become reversed i.e. left is right and vice versa. This is an invaluable advantage because reverse control catches so many new rc pilots out in their early days.
Another big advantage of owning an rc flight simulator is that there's no excuse not to fly, even when the weather is against you, you can still be practising all those maneuvers from the comfort of home, all the time teaching yourself to become a much better radio control pilot ready for that next trip to the flying field.
