The SIG Kadet 40 EG ARF is a great training, or first aircraft. The ARF is very lite and I train folks on it using a AXI 2826/12 motor (similar in performance to Suppo 2826-5) on a 4s 4000-4500 mah battery. While you might be able teach yourself to land and take-off with this plane you would still need some buddy box time (or a lot of simulator time) to get the basic left-right coordination, turns, etc. down. Even with something like SAFE you are risking a lot to just got out and fly without sim or instructor help, I have trained students on the Kadet and they are able to solo and quickly transition (like one flight) to Apprentice or Sensi like planes. So which ever route you go I would recommend some sim and instructor time to get you solo'd without having to buy a lot of repair parts. Soloing does not have to mean a lot of crashes and repairs. I still have and occasionally fly my Carl Goldberg electric Gentle Lady (basically a three channel moto glider which is also a great way to go for a first airplane) that I built as a first airplane in 2004, By the way there is a Kadet "swap" file for the Real Flight simulator that is dead on in flight characteristics.
