I soloed on my own with no instruction on a Right Flyer 40 7-8 yrs ago. It wasn't much of a problem. I had lots of experience with airplanes and am a pilot. The only weird thing was the control reversal when it was coming back at me. I had a great book specifically about building and flying the Right Flyer. It taught me everything I needed to know, especially the "move the stick towards the low wing" trick with reversed controls. For me, the most useful part of the book was just the building tips. Even though it was an ARF, it still seemed like a daunting task for someone who'd never handled a R/C plane before. I haven't flown R/C since then, and I'm just now getting back into it with a H9 Cherokee 40, which should be here anyday now.
