I had a 4 Star 60 with a OS 61FX which provided ample power. It would not quite hover with a 12x7 APC. I built mine stock but if you browse around, you will find a host of modifications. The most popular of which seem to be removing the dehideral and removing a bay from each wing half as mentioned by LuvBipes. I agree that if this is your first low wing plane, build it stock.

PieGuy, you will like this plane better than your trainer, lands really nice but a lot more precise and fun to fly.
