RE: Multiplex Magister RTF
Well, elderly doesn't really describe your R/C experience so just make sure that you let an experienced R/Cer fly it first. The best scenario is if you can find someone with a Futaba or Hitec radio and a buddy cable so he can train you.
The plane flies gentle and stabile but the flight times are short for learning which is why I am replacing my ESC with a Jeti [link=http://www.hobby-lobby.com/jeti.htm]JES030[/link] 30 Amp Microprocessor Motor Controller from Hobby Lobby so I can use a 3-cell Lithium pack. Alternatively, you can buy an 8-cell GP3300 NiMH pack for much longer flight times.
Good luck!
