RE: Need a good second plane
A spacewalker or spacewalker II are good planes if you a learning to fly a low wing. I would also suggest a super sportster. The 61 size engine would be to large though. Seagull models makes a good affordable spacewalker. And your 61 engine would fly it nicely. I had one and really enjoyed it. I now have the 1/3 scale from SIG. They are very stable and easy to handle in the air and on the ground.
