RE: 2nd plane; low wing
My second plane was a Seagull Spacewalker II. Nice scale looks, great ground handling, and handles wind very well. I'm in Oklahoma so being able to fly when it's windy is VERY important. I have never flown the 4* or Tiger 2 but like the looks of scale planes better. the Spacewalker is easy enough to fly while still being a good step up from your trainer.
