I have taught3 people to fly on the PTS Mustang. Two of them I had to put on my trainer first ,bigger , easier to see and fly.Then after they got a few flights under thier belt , moved them into the PTS.The 3rd guy was a Heli pilot and he still fly,s it. So if you get some help with the PTS, you more than likely well be fine.
Being self taught is fine, but be prepared for many up,s and down,s. Stay with the foamies, like a Super Cub and make sure you have easyaccess to parts.
Or go to a local club and see if someone has a trainer for sale , it,s not unusaul that you can pick up a RTF and goodies from some one moving into thier 2nd plane.
Best advise I can give you ,is go to your local Club , You,ll hook up with guy,s , just like you,ve meet here on RCU. that well be happy to get you started . You,ll spend less money and learn faster in the long run. I,m self taught and it was a little spendy .lol
