This is also a truth: Bigger generally flies better/Bigger generally costs more. If your buying and building the plane, this might be something to consider. Most beginners don't have access to a trainer supplied by the LHS or the local club. Further, I think there are many benefits to building one's own first trainer. The process of building teaches building skills and the mechanics of flight and gives a grasp of how to repair the inevitable damage which will occure.

I think either of the planes you have proposed will work fine for you, provided you find help with an instructor.
