This thread seems based on the assumption that most modeler-built models are stronger and safer than most ARFs. I think that assumption is questionable.

First, most hazards are the same for ARFs and non-ARfs. Poor assembly, poor setup, ill-advised choices of servos, batteries, engines, etc., careless and unskilled operation are all the same for all models. Lots of models are flown in damaged condition until something fails and they crash.

Next, is there that much difference between ARFs and non-ARFs? The assumption is that most ARFs are faulty and most non-ARFs are well-built. We've bought shiploads of ARFs and how many have proven faulty? I've seen some owner-built planes that were downright scary, it was a relief to see them rekitted. Consider the number of kits that are the builder's first kit. How many of those are truly well-built?

My point is that I don't see a significant difference between ARFs and non-ARFs from a safety viewpoint.
