RE: ARF's and building...
It's just progress!
There was a time when exactly the same was said about kits (and I mean 'kits'! All that was supplied was balsa sticks, and sheets with the ribs and formers drawn on them, with poor ink, and definitely no pre-bent wire for landing gear!). It was cheating to buy a kit, when you could buy the stock balsa and use a plan.
"'A plan?' You should be designing and drawing your own!"
As with any development, there are good and bad things about it.
One thing is for sure. The average time actually spent flying has dramatically increased!
