I would like to know where I can buy 15, 25, or 30 size electric planes. Horizonhobby only sales of few of them. I do not want 46 or greater.

Horizon.com
click Airplanes
click E-flite
click almost ready to fly
click sort high to low

You will find like 25 planes under .40

Links below would be my first 4 picks

For kits try Sig. http://www.sigmfg.com/

Try some of these places - the majority of them ARE NOT RTF. You will have to install the motor, esc, servos etc.

E-Star Models http://www.estarmodels.com/

Hobby Lobby http://www.hobby-lobby.com/

Nitro Planes http://www.nitroplanes.com/

Hobby People http://www.hobbypeople.net/

Hobby Zone http://www.hobbyzone.com/

Easy Tiger Models http://easytigermodels.com/

These sites should provide a variety of planes to choose from.
