I guess my reason for suggestuing the Midwest planes are 1. It was my first "gas" kit to build - even though now I'm pretty sure that it's an ARF, 2. I learned how to fly "gas" on an Aerostar (I actually started out flying gliders). I have flown plenty of students on other trainers,(and have owned a few different ones) and yes there might be some better and a few worse. In fact, my son's trainer is an older Pilot ARF, but it sure flies well.
I personally think that if a "newbie" builds a kit instead of an ARF that they will actually get more satisfaction from the plane itself. Nothing like transforming a box of sticks into a flying machine! These are just the words of an old "balsa farmer"!!
