RE: GP Trainer 60
One of our club members has a Trainer 60 that he thinks he built around 20 years ago. It has some dings but is a solid airframe and he loves flying it. He loaned the plans to my brother so eventually there will be a second one.
When we first saw it we thought it was a regular primary trainer. After looking at it closely we realized it is really more like an aerobatics trainer. It seems like it's more like a "stick" than a "trainer" in many ways.
