RE: Good trainer plane???
3D planes and Trainers are very different from each other in design and performance .
Trainers are designed to teach you the skills needed to move into 3D and has a stronger airframe , which well handle the {Ut-Oh`s} better. 3D plane are built so light , that a hard landing will break them.
I just moved into 3D a month ago. On 3D rates there is no room for error . I have had a few humbling experiences , at which time I drag out the trainer and go back to the basic`s for a while.
