I would suggest a sig mid star or four star. The mid star is the same as the four star just with the wing moved up. THe mid star is a kit only but it is not hard to build at all. It was my second plane which was build when I was 16. I believe the four star is available in both kit and arf forms. You could fly a 60 four star with that motor and it would be a good combo. You can make it fly gentle or make it more livily as you continue to improve. It is however not a trainer but can be used as a great second plane.
