I agree with Balsa, Sigs are trully trainers, not hot rods with a dihedral wing. I learned on a Seniorita as did the 2 guys who taught me and I have taught many others to fly on mine. I have see guys with Alphas, Towers, extra easys and so on that just couldn't get it and usually piled them up before learning, I turned them loose with my Seniorita, now they are pilots.
