Ok,
For sake of discussion (not argument, I'm not frustrated and I hope you're not

) I understand that you are technically correct. However (just my opinion, please don't be offended), if I knew nothing about rc planes (just like 5 months ago) and read that post I would interpret that most trainers are pretty much the same.
So, being the tightwad I am I may scurry off and buy the cheapest trainer I could find not taking anything else into consideration because from that post I woud come to the conclusion that it doesn't really matter what I choose, they are all pretty much the same.
Then I have my new plane together, I go to a club and I see all these different kind of trainers and I am bummed out because I like the other guys better. Or maybe the other guys is easy to fly. Maybe the other guys flies better, etc... I would then be mad that I didn't do more research and based my decision on the FAQ post. I guess the post would be better if under that it briefly stated some of the characterists of some of the more popular trainers. That way you woud make a choice that you are more comfortable with.
Just my opinion, everybody has one. But I think there is a chance of misleading. Again. I am not aguing, simply telling you my point of view.
