I orginally posted this in giant scale, but it probably fits better here. This weekend we had an air show at our field with a pretty big crowd of spectators. I realized that nobody had a scale like biplane with smoke for barnstoming crowd appeal. So, I thought I'd build one, but can't seem to find anything. Would prefer something big enough for good smoke with a round cowl. Any Ideas? or should I stick to something more modern like an Ultimate?
