RE: Sig 4* question
I have a 4*60 for my second plane and love it. I have the ARF (red). In fact, I flew it today. Once I got used to it, I like it better than my Tower Hobbies 40 trainer. I agree with all of the previous posts in regards to it's taxiing characteristics and takeoff. On takeoff, remember to neutralize the elevator just before the tail wheel comes up. On my third flight, I forgot and the plane shot straight into the air! Fortunately, I kept the throttle wide open and pushed the stick forward a bit to keep it from stalling. Very close.
If you're flying into the wind when landing, it glides very much like a trainer. But if there's no wind, my experience has been that you need to "fly it in" and not rely on it to glide like a trainer.
