Also, Dihedral was mentioned. That's where the outside tips of the wing (furthest away from the fuselage) are higher than the area where it meets the fuse. This helps with stability and helps the plane "right itself" while flying. Many three channel planes used this when they didn't have ailerons and only used the rudder to "steer" the plane. Many trainers will try to "tip" when you use the rudder. If you try to turn to the left, the plane will likely "tip" to the left also. With a lot of dihedral, what happens is that the wing to the left of the fuse will get more level (flat) with the ground. And, remember, that flat part creates lift. On the other side of the wing, that part is now pointed UP more than it was before. It has less lift due to the high angle, relative to the load of the rest of the plane, So, what does it do? It drops. Bringing the rest of the plane with it until it equalizes when both wings are level with each other. It has successfully "righted" itself!
These characteristics can be quite beneficial to the new flyer, and even afterward, can still provide the enthusiast with a very enjoyable, slow-flying and relaxing way to enjoy the hobby, even after they are well versed in flying warbirds and 3D. So, months or years down the road, remember this and by all means, NEVER SELL your trainer!
