I'm kind of neutral here, but I will comment that SPADs are much more durable than balsa . . . and that is a good thing because of the way the ones I have seen fly and respond. Now, I'm sure there are highly developed SPADs that perform well. I just have only seen the ones that some poor schmoe downloaded two images and a six paragraph construction article and slapped together with salvaged parts cut from a synthetic kitchen chopping block and election signs swiped from lawns. We only had two guys in our club that futzed around with them, and the rest of us were underwhelmed. They fly, but not well. Wings generally too narrow, no lateral stability and they ground loop like horseshoes coming in. The ones that did fly better were the light profile designs: 2-D models doing 3-D stunts. If you're the type that flies on the prop they'll probably keep you happy.

A softball is durable, will fly if you push it with enough force, but it is not an aircraft. I'm not interested in maneuvers that can be duplicated by draping the wheels over a clothesline.
