RE: Second plane... need help
I would avoid any of the scale planes (Piper, Roulette, Decathalon, etc) and lean towards the "Sticks" or the Super Sportster. I would also check out the Goldberg Tiger or Sig Four Star. Out of your list, my choice would be the Great Planes Big Stik 40.
My second plane was a Four Star 40 kit, and I love it.
