Ok guys, look again............. He never asked for help. It was a low wing, that led me to believe that this wasn't his first rodeo.
Our field is a leader in training. last year we soloed 47 pilots. It's not unusual to get a trainee at the field that's only here to learn, then moves on to a club closer to their home. What's surprising is in some cases the trainee was "sent" to us buy other clubs. (we don't mind at all )
Our trainers ware badges on our collar, this makes us easy to approach. (mine was on).There were three badges there that day because it was a Tuesday. ( training days are Tue. & Thur.) On training days there usually around five.

As for not following the instructions, I've never built a ARF, but I have assembled toys and other things that came from that part of the world. I would imagine that it is written in "broken English". ( in this case "crashing English" )
