Nick,
You have a good start on the hanger for sure. I'm not sure what direction you want to go. What is your goal? The Sig SE is ceartainly a great "yank it through the sky" plane and the 0.60 size Extra will make a wonderful scale plane. Everyone has a stick and a Cub.

It sounds as if you may want to try a pattern plane. They are great fun and there is a wealth of information here regarding same. The UCD is really a nice plane and mine will be in the air this weekend. CAP232 the following hopefully.

Since you have most except the pattern type and you mentioned 3 different ones you may make it your next challenge. Don't forget the bipe as mentioned above. Enjoy.
