It was easy for guys to fly the wrong plane when there were 9 up at a time. I remember some trying to find bright color schemes. Those days were a lot of fun. I got burned out on fixing planes all of the time. I pretty much only do scale now, as I like to have them around for a while, and while it is probably more work in the end, I am currently finding it more gratifying. So many aspects to this hobby now.
I would guess many that would build these kits in 1/12th scale now would make them electric. Although, I would not mind having a slightly blown up version of the TA 152. Maybe 1/7th scale. Something in the 60" range.
