The bigger cubs fly tons better that the the little guys. They are much easier to take off, fly and land. If you are worried about the plane floating by in ground effect, go for the clipped wing version...it will settle in a lot quicker, and is a little more agile once you are in the air, if you like to kick your heels up once in while... The full span cubs are great flers in their own right, expecially putting around on a quiet evening or doing touch and goes...
