One of the main advantages trainers have to ease-of-flying comes from their lower wing loading.

That is, they have large wing areas for the total weight of the plane.

This makes them much more forgiving with regard to the speed needed to make it fly. Trainers therefore need less speed to take off and land.

That's a definite advantage when taking off from grass, as you can get away from the bumps and drag of grass sooner if you can achieve flying speed sooner.

Lots to learn, and that never goes away in this hobby (I'm glad to say!) but also lots to be satisfied and have fun with on the way.
