Take a good look at the ZAGI 400X or maybe even the new Zagi FIXX. No gear, no rudder, (electric) engine always starts, virtuallly indestructable and great, stable fun! It can fly pretty slowly and is nearly impossible to spin or snap accidentally. I'm new to this game myself, and wish I had bought my ZAGI 400X as a first plane. I think there is a promotion for the kickoff of the new FIXX going on now.

Looking to teach my grandsons on these also.
