I had a little Kadet Jr. and it could do rolling circles !!! It would blow people away. But the fact is, they were easy. Hard over, then up down, up down, up down....... Three channels are a great way to get started. In my case, they were a step up from the 2 channel planes I had flown the first couple of years. The Kadet Jr., the Colt, the Eaglet and a bunch of other models made wonderful three channel planes. I'm surprised I don't see more of them . Folks nowadays tend to jump right into a four channel plane, what we used to call full house. But you don't need to. Three channel planes tend to instill confidence and just simplify things. I think it is a path that is overlooked far to often in the rush to be a pilot. I think 4 channel planes tend to overwhelm newbies and make them nervous. A good 3 channel will have them smiling and enjoying themselves much sooner. Many folks will tell you they are unnecessary. Well, I guess that is more true than not. But the idea is to have fun and provide a positive reinforcement as soon as possible. Success early will motivate the trainee to come and fly their brains out every chance they get. And that establishes the proficiency that allows them to progress rapidly and independently. Teach a man to fish........that is what a 3 channel does.
