Does anyone have a good suggestion..

[a_sprague]

for good arobatic planes, preferably in multiplex style foam (so to take a few bumps!) but that are slightly smaller and lighter than the Acromaster but bigger than your typical light 3D indoor foamies?

Thanks

How about a all EPP foam plane. Should take some major abuse and keep flying. Download the PDF file to see how its built.
