Some kind of ugly stick is a good model for someone who already can fly a bit. Get a buddy box instructor and dial back the control throws so the model is not to sensitive to begin with then when you progress it will be aable to give you a bit more than a trainer.

I know someone did a version that would take a 150.

The larger of these is rated for a 120 4st. See [link=http://www.greatplanes.com/airplanes/gpma1220.html]CLICKY[/link]
