RE: Oops...
Grant,
I completely agree with kingwoodbarney on the difficulty issue. My Eagle II was quite a bit harder to fly inverted than my P-51 and the Tiger. I found that when I went to the Tiger from a trainer, my flying improved greatly. What is a virtue for the trainer plane becomes a hindrance when you want to move beyond the basics, in my opinion. I could manage to keep it inverted as long as I wanted, but it was quite a bit more work than on a more maneuverable plane. Outside loops were also really quite weak. Almost got myself in trouble a lot of times thinking I had more down elevator than it really did. That said, some of the more advanced planes can get you in trouble a lot quicker, which I'm sure you already know. But.. I think if you have the basics down and were comfortable enough for inverted flight in a trainer (barring, of course, the dumb thumbs that turned it into splinters), maybe a second plane will be a lot better for what you want to do. If you take your time with the second plane and don't hot dog it right away, I'm sure you'll be having a LOT more fun doing outside loops and inverted patterns- and will probably get a lot better a lot quicker.
I like the Super Sportster, and it looks really cool to boot! Can't go wrong with the Tiger, and the Midwest Aerobat looks promising too! I like the Sig 4* also, but I'm assuming you have a .40 to put in it and they only sell the .60 size ARF on Tower. Never flown the SE, but have seen a lot of them at the field and they look really cool!
Whatever you do, keep us updated and let us know what you think of flying your second plane....
