RE: Sig 4 Star vs GP Super Sportster
I got a Super Sportster ARF for my second plane. First couple flights my nerves were making me shake. After a few times out with it, I was comfortable with it, and began flying basic aerobatics more casually. It's a great plane in my opinion. Wheel pants are fine for blacktop, but for grass bigger wheels are the way to go. I have a os 52 four stroke in mine, and I love it. You'll find it won't get too crazy, but will feed a need for speed when you want to.
