Very good advice there and I agree with that 100%. I still fly my trainer (SuperStar 40), but I have converted it to a bolt-on wing, taildragger and put a Saito 72 up front spinning an APC 13x8. Have you ever seen a trainer torque roll. It is a wild sight to see and has become a crowd pleasure during fly-ins. I even left the dihedral in the wings.

I also placed a little better photo of my 4*60. As you can see, many have agreed that the 4* is a great second plane in any size category.
