If yo are splitting up the purchases f the stuff to fly RC... you can gain abit of experience flying anyway.... Get the radios system first, then go to Wal-Mart and get one of the appx $5 foam gliders (4 1/2 foot Span!) You can put strapping tape n the bottom of the wing )from tip to tip) and install 2 servos the RX and battery to give it rudder and elevator control... go out and practice some gliding.

Then you can get the ARF version of the trainer and the glow engine later, and be a little ahead of the game.
