I would like to get a decent plane for my six year old to learn to fly. He's flown the 2 channel jobbies (which I really dislike) but the darn things won't stay in the air during a turn so we're constantly smashing them into the ground and the flight time is om;y about 4 minutes even when we keep them in the air. I wold liek something that I can take to the park with him. Are their any electric trainer models that will self level when you let go of the controls? My first Nitro trainer woudl do that. Anyway, it's been several years and I hav enot kept up with the hobby so when I started looking and found literally hundreds of electric park flyers I had no idea what to get for him. I am leaning towards a sail plane due to their slwoer speeds and slower response times. let me know what you all think.
